Problem with Django! Please help

2012-01-27T10:34:00.000-08:00

please help me out! I'm not getting it! below are my codes:
In models.py:
class Login(models.Model):
username=models.CharField(max_length=50)
password=models.CharField(max_length=50)

def __unicode__(self):
return u"%s-%s" % (self.username, self.password)

class LoginForm(ModelForm):
class Meta:
model=Login
fields=('username','password')
in my views.py:
from django.contrib import auth
from django.shortcuts import render_to_response
from django.http import HttpResponse, Http404
from django.template import RequestContext
from django.http import HttpResponseRedirect

def login_view(request):
username=request.POST.get('username', '')
password=request.POST.get('password', '')
user=auth.authenticate(username=username, password=password)
if user is not None and user.is_active:
auth.login(request,user)
return HttpResponseRedirect("/homi/")
else:
return render_to_response('login.html',
{'LoginForm':LoginForm},context_instance=RequestContext(request))

def logout_view(request):
auth.logout(request)
return HttpResponseRedirect("/logme/")

in url.py
from django.contrib.auth.views import login, logout
(r'^accounts/login/$', login_view),
(r'^accounts/logout/$', login_view),

in my template:
{% extends "base_meek.html" %}
{% block body %}
<form action="" method="POST" />
<table>
{{LoginForm}}
</table>
<input type="submit" value="Log In" />
(% endblock %}

After creating all those codes. I tried to login with my password and
username, but if failed! So I added the username and password through
Django admin. So after adding it, I tried to login with with username
and password, it works!

My question is, is that how it's suppose to be? if that's the way it
should be, so it means I will be adding users manually before they can
login? What about other fields like, country, state etc in my
RegisterForm, will it be added automatically??
Am I doing something wrong? Please I need answers because django is
driving me crazy!!!

First off, the instances of "0" at the end of the first two lines should be [0] (surrounded by square brackets), but I'm assuming that that's an artifact of the email transport.

Past that, your code doesn't actually *do* anything, other than pull two objects out of the database, and save them again, unmodified. Let's look at the method you've pasted, line by line:

customer = Sale.objects.all().order_by('-id').filter(email_address=email).distinct()[0]
this = Count.objects.all().order_by('-id')[0]

This part retrieves two objects from the database. You may want to guard these two lines with an exception handler -- if there are no matching Sale objects, or if the Count table is empty, either of these lines could raise a KeyError.

number = this.number + 1

This line creates a new local variable called number, and assigns it the value of this.number + 1. It doesn't do anything to the 'this' object at all.

a = this.save(force_insert=True)

So this line forces 'this' to be re-saved (remember, though, that it hasn't been modified, so the save doesn't really do anything). Model.save() doesn't return anything, so 'a' is assigned the value None.

ref = number
reference = number
name = customer.name
salutation = customer.salutation

Again, these just create some new local variables, but they don't actually change your customer object at all, so this line:

b = customer.save(force_update=True)

Just forces a re-save of the unmodified customer object.

I"m not sure exactly what it is that you're trying to do with this view, but I think that you are going to need some lines that actually update the 'this' and 'customer' object. You would do that like this:

this.number = this.number + 1

customer.reference = number

Then, when you save the objects (and just use "customer.save()", the force_update=True isn't really necessary), then the new values you have assigned will be saved in the database.

If the data is presented as table, datatables is a really nice jquery

Thanks for the additional thought on this. It is a much appreciated
confirmation to me. Last night I was torturing my brain over the
logistics of what I had conceived, and by this morning I had pretty
much concluded that I would have to go the route you are suggesting.
Now I just have to find an existing solution ... or learn Javascript.

I'm presuming the initial data set being sent is the "full" list. If
so, might it not be useful to somehow (Caveat: I'm /not/ skilled at
this, only toyed with Javascript too many years ago) embed a Javascript
action to count the categories, render the filter selections and, when
one is picked, have the Javascript modify the page in-place to display
only the filtered data?

Granted, adding another language on top of Python, Django, and the
template language, may be more than desirable.

RE: Determine gender from first name

2012-01-27T07:20:00.001-08:00

All depends on how many users you have and how accurate you want your data to be. If your language uses specific morphemes for women (usually non-european languages have marked feminine morphemes; male names and pronouns are not marked), then you could write a parser for these names. Yet I doubt your data will be any better than 90% accurate. Don't forget people construct virtual identities and often use loanwords. You could also parse their content (blogs, comments,... *is this legal?) and see which first person pronouns, verbs, etc. they use. If the latter are explicit feminine forms, use a feminine welcome.

So, I would just work around the gender-specific welcome. Replace it somehow. Convince your client it is somehow spooky to directly address the visitor.

Or, even better, add a gender category to your db and register form and convince your client that some day it will prove interesting for data mining purposes.

ipaddress

2012-01-27T04:44:00.001-08:00

Hi all,

First am sorry ,its a python specific question not django based.
I am developing a mobile application, using python in server side. I want to get user's ipaddress(Now user's request not sending ipaddress as a parameter to my server). I am using cherrypy server , Now I take IPaddress using following code,
ipaddress = cherrypy.request.remote.ip
I have a doubt whether this generate an ipaddress in the form xx.0.0.0/32 ( a private range ).?
Thanks

Changes to Google Privacy Policy and Terms of Service

2012-01-26T22:37:00.001-08:00

		Is this email not displaying properly? View it in your browser.
Dear Google user, We're getting rid of over 60 different privacy policies across Google and replacing them with one that's a lot shorter and easier to read. Our new policy covers multiple products and features, reflecting our desire to create one beautifully simple and intuitive experience across Google. We believe this stuff matters, so please take a few minutes to read our updated Privacy Policy and Terms of Service at http://www.google.com/policies. These changes will take effect on March 1, 2012.
One policy, one Google experience

Easy to work across Google Our new policy reflects a single product experience that does what you need, when you want it to. Whether you're reading an email that reminds you to schedule a family get-together or finding a favorite video that you want to share, we want to ensure you can move across Gmail, Calendar, Search, YouTube, or whatever your life calls for with ease.	Tailored for you If you're signed into Google, we can do things like suggest search queries – or tailor your search results – based on the interests you've expressed in Google+, Gmail, and YouTube. We'll better understand which version of Pink or Jaguar you're searching for and get you those results faster.	Easy to share and collaborate When you post or create a document online, you often want others to see and contribute. By remembering the contact information of the people you want to share with, we make it easy for you to share in any Google product or service with minimal clicks and errors.

Protecting your privacy hasn't changed Our goal is to provide you with as much transparency and choice as possible, through products like Google Dashboard and Ads Preferences Manager, alongside other tools. Our privacy principles remain unchanged. And we'll never sell your personal information or share it without your permission (other than rare circumstances like valid legal requests).	Got questions? We've got answers. Visit our FAQ at http://www.google.com/policies/faq to read more about the changes. (We figured our users might have a question or twenty-two.)

Notice of Change March 1, 2012 is when the new Privacy Policy and Terms will come into effect. If you choose to keep using Google once the change occurs, you will be doing so under the new Privacy Policy and Terms of Service. Please do not reply to this email. Mail sent to this address cannot be answered. Also, never enter your Google Account password after following a link in an email or chat to an untrusted site. Instead, go directly to the site, such as mail.google.com or www.google.com/accounts. Google will never email you to ask for your password or other sensitive information.

Django URL mapping parses only path part of the url. Query string part
(part after question mark) are not parsed by url parser but passed in
request GET dictionary.

Question mark in Django URL Mapping

2012-01-26T18:15:00.001-08:00

When I type the following as the normal python function, it returns the correct things:

>>> pattern = re.compile(r'^account_activation\?user_id=(?P<user_id>[0-9]+)&auth_key=(?P<auth_key>[0-9a-zA-Z]+)$')

>>> match = pattern.match("account_activation?user_id=36&auth_key=f9717d96aa4e3452a47955225a60862d07119702")

>>> match.groupdict()

{'auth_key': 'f9717d96aa4e3452a47955225a60862d07119702', 'user_id': '36'}

However, when I do this in the Django URL mapping:

url(r'^account_activation?user_id=(?P<user_id>[0-9]+)&auth_key=(?P<auth_key>[0-9a-zA-Z]+)$',

'activate_registration'),

It seems like the question mark is causing the url mapping not found issue.

Does anyone know why.

Thanks very much

Re: How do you pass dissimilar data from view to template?

2012-01-26T13:55:00.001-08:00

It sounds like you're confused about how to add more than one piece of
information to a template. When you render a template, the template is
given a context, which is a Python dict object. A dict is a bunch of
key-value pairs. So, right now, you're probably doing something like:

return render_to_response('path/to/template.html', {'items': items})

Where items is a list of item objects. You can simply add more key-value
pairs to the dict to add your counts:

items_25_to_50_count = Item.objects.filter(price__gte=25,
price__lte=50).count()
return render_to_response('path/to/template.html',
{'items': items, 'items_25_to_50_count': items_25_to_50_count})

Hopefully this helps with your question.

How do you pass dissimilar data from view to template?

2012-01-26T13:12:00.001-08:00

I am a relatively new to Django, and have just run into a wall, but I
am sure this will be a cake walk for you veterans out there. I have a
list of items I am displaying in a table in a template. That is no
problem I create an object (list of values) in my view send it to the
template and render the table. However, I would like to also show on
my template a bunch of count()'s displayed as links, that when clicked
will further filter the list of items displayed. For example, I may
have items in the list that cost between $25 and $50, my link would
show that there are say 20 items that match that criteria. When the
link is selected in sends a request to the url.py that in turn
executes a view that further filters the queryset then renders
template again.

How do I get the count() info to the template? I do not think I can
send two separate lists (objects) to the template (at least I have not
been able to figure out how yet). I think I need to get the counts at
the view and then somehow append them to my list object, but I'm not
sure how to do that and also, not quite sure how to parse those values
in the template. I want the counts to show separate from the table
generated from my list object, and I am somewhat concerned I'm going
to mess up my table that is working fine now.

I would appreciate any suggestions you have about how to tackle this,
and I would really appreciate code examples because I am still
somewhat Python/Django code challenged.

Thanks.

You can prevent the error by using `list()` to fetch the inner queryset
in a separate query:

total_objects = (obj_assigned | obj_class.objects.filter(pk__in=list(inner_q)))

Re: Django (or other) templates for untrusted users?

2012-01-26T12:28:00.000-08:00

I think that depends upon the context the view provides, and upon what
tag libraries can be loaded.

Objects in the context can have their methods called (with some
restrictions). If your view pre-converts all interesting data to
strings and numbers, and/or sequences or dictionaries of such, then
the available methods are limited so you can review them for safety.

You could also automate checking of any tag libraries loaded against a
list of those you have deemed safe.

Of course, there could be additional vulnerabilities that aren't coming to mind.

MySQL limit sub-query problem

2012-01-26T12:10:00.000-08:00

All,

I have a query. Its working fine on sqlite server but not working fine
on mysql server.

This is the error message on mysql server: "This version of MySQL
doesn't yet support 'LIMIT & IN/ALL/ANY/SOME subquery"

This is the query:

inner_q = obj_unassigned.values_list('pk', flat=True)[:diff]
total_objects = (obj_assigned | obj_class.objects.filter(pk__in=inner_q))

Any help appreciated on how to fix this.

Thanks.

[re-post] MySQL connection pooling - preferred method??

2012-01-26T12:09:00.001-08:00

Hey all,

Not had much luck on this on django-developers, so if anyone else on django-users wants to add their two cents on this thread, that'd be great.

I'm still looking into it, and it looks like the best approach is to create a new MySQL backend with support for connection pooling, but I'm still really dubious because when it gets into those depths, surely that should be in the core... *shrugs*

Penny for your thoughts? :)

To: django-developers@googlegroups.com, Harry Roberts <harry.roberts@simplicitymedialtd.co.uk>

Hi all,

After spending about 30 minutes looking through old tickets, long discussion threads and various blogs, I'm still not clear on the MySQL connection pooling topic.

To quote Russ: "the capability already exists in third party tools, and they're in a position to do a much better job at it than us because it's their sole focus" [3]

Could a core dev (or anyone else with experience on this) clarify which approach is recommended, on the following conditions:

* Safety (should not cause any strangeness with query cache or ORM)

* Performance (should avoid causing Django to open a new database connection on every request)

I found various ways to accomplish this, one of which was to use SQLalchemy[1], another was to stop Django from closing the database connection after each query[2].

I'm hoping this thread will also serve as a final answer for anyone else looking for clarification.

Many thanks

Django (or other) templates for untrusted users?

2012-01-26T12:09:00.000-08:00

Are Django templates safe enough to use templates provided by
untrusted users? Is it possible to limit functionality? I am not only
concerned with what the templates can access, but also things like
being able to consume excessive resources with, for example, deeply
nested loops.

If not Django templates then what? I ideally need simple conditionals
and some way of looping. Mustache is close to what I need (it will
probably do if I cannot find better) but AFAIK cannot iterate over a
tree. I also just found
StringTemplate (from stringtemplate.org, not the standard library!),
Anyone tried either of these?

No -- but, as the "python ..." line indicates, you need to be at an
OS level command line (or use an IDE that implicitly spawns a subprocess
that is equivalent to that line), not inside a python interpreter.

"runserver" is, to my mind, the "Django" command. "manage.py" is the
a Python script generated by Django which processes management commands
for the Django installation.

The main suggestion I saw (and my apologies if I'm repeating other
information -- I'm a bit behind in the group today and haven't read
ahead) was to install the ActiveState Python build (it appears they've
renamed the non-supported/freeware build to "community edition").

ActivePython for Windows includes the win32 extension libraries (if
one wants to go to native Windows code -- though the now standard ctypes
library permits similar capability if one knows the API), and PythonWin
IDE (as I recall, this started life as an included demo of the win32
extension libraries <G>).

PythonWin isn't the fanciest IDE -- no overarching "project"
management, just multi-window file access; autocomplete won't work for a
module until it has been imported via the interactive window (since some
modules have to be imported for PythonWin itself, those autocomplete
without explicit imports). I believe it supports the Python debugger
(I've not written anything complex enough to need formal debugger --
wolf-fencing* and rerunning works for me). But it doesn't cost
anything... Full Komodo is a $$$ product; I don't know if there is a
stripped down version.

Moving a file manually

2012-01-26T00:44:00.000-08:00

Hello,

I have a model with a FileField, that I use to store some user
uploaded files. After a while, I changed my mind about where to store
the files, so I was just wondering if there is a way to manually move
a file, and then update the location of the file as stored in the
database. I'm using a plain models.FileField, with no custom Storage
or anything advanced.

Re: Fixture Funny : 1st Row Of Each Table Missing

Re: [pinax-users] Learning Django+Pinax - Recommend books and/or tutorials?

2012-01-25T21:39:00.001-08:00

I think I am qualified to give you advice. When I say "qualified", I really mean it.

First, I am not a very strong programmer myself. Even as a CS student, I always feel like I am behind. Nontheless, I am always eager to learn and am very determined to debug for days.
Python is not a big language like C++. There might be a faster way of writing things in Python (such as loop vs comprehension), or making a generator. That's not important. I know Python for three years, but I don't write Python code a lot. When I need to know how to write a particular line in Python, I google it. If not, I post questions on stackoverflow.com (of course the question has ben appear good.....).

I am now doing this research, developing a cloud computing application based on Django, Pylon, and many web technologies (let alone Unix and sysadmin knowledge). Forutunately, I am the webclient developer, and I deal with Django (we choose pinax as a starting base).

I read the Django book twice. But the first time I gave up half way. The second time reading it I took my time. Django is actually very difficult to develop because the framework is powerful. Python as a language alone is very small. It takes no more than 100 pages to teach you everything you need to know about basic python and advanced techniques. Python itself is huge because of its rich libraries.

So little Python is not a problem. Read "Learning Python". Read Definite Guide to Django. Get a django1.3 cheatsheet online. Learn to use virtualenv (or pythonenbrew), pip, yaml, and fabric? I think virtualenv and pip are necessary.
Don't rush him. Give him two weeks to digest the first half of learning python, and definite guide to django. Give him two weeks, and he will be happy. Then let him read the source code, and if the project is small, printing out source code isn't bad at all. Otherwise a few days of exploring will serve him well.

I am picking up a legacy work, and it took me a while to get a hang of it for a django beginnger.

Pinax itself is like a wrapper on top of django IMHO. There is no mystery.

When you are developing your Django app, the development server that
comes with Django (python manage.py runserver) works fine on Windows.
When you are ready to move things into production for everyone else
access, you should not use the development server; instead you should
use a proper web server, e.g. nginx, cherokee or Apache. Those web
servers tend to be better documented on Linux.

If it makes things easier, just do everything on Linux.

I still don't quite understand. Can you explain more? I would think this means that my Django files should be on a Linux portion of my web server? I am with Bluehost.com

I have installed ActiveState and will give it a try. I have my VS up and running with Python Tools for VS so that should be okay.

The keywords were 'in production'. The development server (i.e. python
manage.py runserver) works fine under Windows. But when you want to
make the website accessible to your audience (the internet, company
etc.), you should host that on Linux.

That's one way. It's a bit more complex than simply doing everything
inside a Linux VM. Komodo Edit also works in Linux as well.

Let me see if this what you mean... so when I want to run "python manage.py runserver," a Django command I should steer clear of Windows?

So I should install ActiveState Komodo Edit to Windows. Which in turn well help me to work with my Django server through a Virtual Machine?

If I have this right I should install my CPython distro to VS and build my Python on Windows in VS. Then on the side I should have a VM running with my Django server (aka my Django project)?

Python Tools for Visual Studio should automatically detect CPython if
you have that installed. If you haven't, I suggest you download an
install a CPython distribution called ActivePython Community Edition
(http://www.activestate.com/activepython/downloads). It will set up
Python in your Windows environment properly, which the official one
doesn't seem to do right (judging by the posts here about Windows).

The bonus with VS is the great debugger, which works with CPython as
well. Many of the IDEs mentioned are just great text editors, and
don't include a debug environment (i.e. the ability to set
breakpoints, explore stack, step through code visually etc.). Some do
include such an environment, including PyCharm and PyDev.

PostgreSQL also works fine on Windows. No idea about all the GIS stuff
though. If you're comfortable with using Linux, then go for it, but
most of the basic stuff you can do on Windows (until you need other
bits of software to make things work, like Redis). Unless you have a
preference for Windows though, I wouldn't use it as a Django app web
server in production; there's far less support on the net to help you
out when things go wrong.

I use ActiveState Komodo Edit on Windows to modify files on my Linux
VM which runs the web server for my Django apps. It means I don't get
a debug environment though; working on finding something to make that
work.

Re: django docs unicode return u'%s %s

2012-01-25T15:00:00.001-08:00

Just to fill in some more info, __unicode__ methods are also part of
core python and just happen to appear a lot in django code because of
its preference for 16-bit unicode strings (though I think the methods
are actually mostly invoked in the admin). There is also a __str__
function for "ordinary" (8 bit potentially mbcs) strings. (This is
Python 2.x; Python 3.x is somewhat different.)

User-defined __unicode__ methods are overrides of builtin methods that
all objects are guaranteed to have. As the __...__ in the name
suggests, these methods are called implicitly in certain kinds of
expressions. Two cases I know of in Python 2.7 are expressions of
form unicode(obj) and expressions of form u'...%s...' % obj (and I
assume other format expression tyopes where the format string is
unicode). In both, obj is converted to a unicode string using
whatever __unicode__ method is defined for the object.

Cool, found 1.3 source:

django/branches/releases/1.3.X
<https://code.djangoproject.com/browser/django/branches/releases/1.3.X>

Looks like maybe FilterSpec might be what I want:

<https://code.djangoproject.com/browser/django/branches/releases/1.3.X/django/contrib/admin/filterspecs.py>

At least now I have a better idea of what to Google for "django

Just as an update, I found this:

It is up to you. The purpose of the __unicode__() method
is to return nice and human readable Unicode string
that represents the object. It is used for example
in the admin mode that was designed to be general for
whatever model. Whenever the admin template needs to display
textual representation of the whole record as a string, it simply
calls the function for getting a string representation of the whole
object. The function calls the __unicode__() method that
is implemented by you. Whatever you want to see in the case
should be created by your definition of the method. Try to
put there strings that you can be sure they are yours -- just to
see what the method is called for.

Try

u'{}#{}***{}_{}'.format(self.project_and_task,
self.project_number, self.date_created, self.requested_by)

Also, you are not forced to display all the parts of the record.
It is only for the display purpose. It should be just a string
that represents the record. You probably want to put something
meaningful there.

Have a look at http://docs.python.org/library/functions.html#unicode
and http://docs.python.org/reference/datamodel.html#object.__unicode__

modelForm validation -> model validation -> trigger field validation?

2012-01-25T11:34:00.001-08:00

hi there,

has anyone of you an idea in which cycle the field method of
ForeignKey.validate is triggered?

I have a custom ForeignKey Field where i override the validate method.
So i expect that

ModelForm validation triggers
-> Model validation (clean methods) and this triggers
-> Field validation of all contained fields

But this seems not be the case. Has anyone of you an idea?

Best Regards

Please re-read carefully the error message and the line it points to.
The error message says "SyntaxError: invalid syntax", which means your
code isn't valid python code. The cursor points to where the syntax
error happens, that is the whitespace between 'upload_to' and
"documents".

The valid syntax would be:

upload_doc = models.FileField(upload_to='documents')

I strongly suggest you take some time to learn Python - at least do
the official tutorial - if you hope to get anything done in Django.

As the error message says, it is invalid syntax, you forgot the equals

Re: django docs unicode return u'%s %s

I'm using python 2.7.2

return (self.project_and_task, self.project_number,
self.date_created, self.requested_by)

to understand (i think the new method makes a little more sense?) the

is the two spaces between each {} two seperate the individual strings

URL Validation is done in django, not in the database, so there's no

Caching and excluding in a template

2012-01-25T04:28:00.000-08:00

Hello,

wondering if there is any easy way to exclude a little part from a
template to be cached, on every site there is a the usual register/login
or you are logged in with a user menu, back in php+smarty times it was
easy solved using a dynamic tag to easily exclude a small part from
being cached.

So far I only saw you could turn off caching for logged-in users or fine
grade what is being cached, the first I dont want (only caching stuff
which looks same for all users except the user menu) and the latter
seems to be quite some work compared to just exclude a litte part in the
base template.

Greetings,
Thorsten

This is wrong. The prefix 'u' means that the following string is a Unicode
string, nothing more or less. It is a fact for Python 2.x. See
http://docs.python.org/reference/lexical_analysis.html#string-literals

The % character after the unicode string means "string interpolation",
i.e. replacing the placeholders inside the string template on the left.
See the String Formatting Operations http://docs.python.org/library/stdtypes.html#string-formatting-operations
You will also find the placeholder types there.

>> > Krondaj wrote:

The .format() method of the string type is the newer one, introduced
in Python 2.6. It is the preferred way now. But you can use it only
when you can be sure that the Python is 2.6 or newer. The command
in your __unicode__ method would look like:

def __unicode__(self):
return u'{0} {1}'.format(self.first_name, self.last_name)

The '{0}' is the placeholder for the self.first_name (zero'th argument,
the '{1}' is for the first argument (self.last_name), etc. Since Python 2.7
(if I recall correctly) you need not to use the numbers inside:

def __unicode__(self):
return u'{} {}'.format(self.first_name, self.last_name)

You do not want to return only...

def __unicode__(self):
return (self.first_name, self.last_name)

... because you want the method to return the unicode string representation.
Without .format() or without the % the method would return a tuple with
the information, not the string.

Re: get_FOO_display() for generic/variable choice fields

2012-01-25T02:21:00.000-08:00

My Python-expert partner suggested a clever workaround as follows:

As I'm already running through the model._meta.fields beforehand to
create header row for my .csv file, I can build a dictionary of the
choices to refer to later.

choices_lookup_dict = {}
header_row = []

for field in model._meta.fields:
# create header row for csv file
header_row.append(field.name)
# Add lookup dictionary of choices to dictionary of fields
# i.e. creating a dictionary of dictionaries for each choice field
if field.choices:
choices_lookup_dict[field.name] = dict(field.choices)

This could be quite expensive for large choice tuples such as country
lists, but at least we're only calling it once.

So now in my main loop I can use the following code to lookup my
verbose choice value:

for field in model._meta.fields:
val = getattr(obj, field.name)
if field.choices:
val = choices_lookup_dict[field.name][val]
row.append(val)

We assume that get_FOO_display() must be doing something like this
anyway!

It uses nltk package for predicting, but as Kenneth said, it won't be 100% perfect. You can expect 80-90% success.

not possible in my opinion. There may be some languages where a name

Maria, Rama, Krishna, for example are not gender specific.

Fixture Funny : 1st Row Of Each Table Missing

2012-01-25T01:18:00.001-08:00

Hi. I'm having a funny issue. I have a fixture for my static tables.
They are all populated via syncdb using the fixture. On my sqlite test
environment it works perfectly. On my production environment, with a
MySQL database, the data is populated into the tables via the fixture
except for the first element in each table referenced in the fixture.
Has anybody encountered this issue?

Is it maybe the pk which is defined as 0 rather than 1?

Here is an excerpt from my fixture:

[
{
"model":"lookups.DayOfMonth",
"pk" : 0,
"fields" : {
"code" : "1",
"display_value" : "1"
}
}
,

I don't know if there are any databases or webservices available for the purpose. But how would you handle the exceptions ?! Like if it does not exist in the db, and common names used across genders ?!

Re: django docs unicode return u'%s %s

2012-01-24T22:40:00.001-08:00

If I may say, 'u' makes it easy to return variable with any hassle.
And %s rep each string in your script. I think there should be other
ways to go about this. Hope you get my point?

As mentioned, this is standard Python (pre 3.x) string interpolation
(formatting).

u"any string"
defines "any string" to be unicode rather than 7-bit ASCII; in Python
3.x, all strings are unicode and one needs to specify if plain bytes are
needed.

"some string with %placeholders" % (some, tuple, of, values)
replaces the placeholders with a textual representation of the values
provided. The %s placeholder is most common as it handles any object
that has a method to produce a string representation ( __str__(self) )
-- which is pretty much anything. One can use others -- similar to the C
runtime library printf() format strings.

The main thing to take into account is the division between being IN
the interpreter and being in a command shell.

">>>" is the normal prompt from inside an interactive Python
interpreter session. At this level you can execute Python /statements/.

Any example that reads something like

[python] <filename>.py <arguments>

is meant for a command shell. Actually typing "python" first may be
optional if {Linux/UNIX: the .py file starts with a proper #! line
identifying the Python interpreter to be used | Windows: .py files have
been defined as an "executable" extension (in which case, even the .py
may be optional) AND .py files have been associated with the Python
interpreter}.

Re: SQL and times for ajax requests?

2012-01-24T19:54:00.001-08:00

I figured out a simple workaround , instead of returning a xml or json
response from view I temporarily changed the view to send back a html
page and Django-debug-toolbar gave me the data.

It is pain to do it for all ajax requests but I can do it for one I am
most concerned about.

Sam Lai,

I am interested in PostgreSQL. I've heard it is good to use along with Django. More specifically to work with GIS. I'm very interested in the Geographical uses of Django. In particular GeoDjango. As I continued to learn more about this web framework I hope to be able to work with databases such as PostgreSQL and work with Geographical information/code. Maybe this helps give a more representation of what I want to do with Django. I see on GeoDjango's documentation that the Linux mascot Tux is there. I keep thinking I am wasting my own time with Windows here and that my real destiny here is the real programmers language. To put it in short terms. Do you think that is true?

I want to unleash the power here of the interactiveness as well as be able to have my Python/Django to work alongside with GeoDjango and PostgreSQL.

Do you know anything about this?

Is CPython along the horizon for me because IronPython will not interact well with Django like you said? Should I consider trying to install Python/Django/CPython, etc on Linux to start my development?

Thanks,

is this the correct way to form a model of my data?

2012-01-24T17:26:00.000-08:00

Hi everyone,

I'd really appreciate your help here!

I have just designed a model for my data that I want to publish as a
webform, that people fill in, however there are only certain bits I
want them to fill in as i'll be filling the rest in later as the work
progresses. is the model here correct (i'm not sure if i've imported
all the correct modules).
I have put an asterisk next to the ones i don't want them to be able
to fill in (i'd ideally like to have them have to input a user name
and password)... but i don't know how to do that... i'm only at the
model stage at the moment.

i have changed the names to protect the guilty!

My questions are i suppose:
1). is the model correct?

2). do i need to change something in the asterisked code (this is not
actually asterisked in my model.py code) so that only the person who
is requested to do the work can add these details

3). have i imported all the necessary modules

4). at the is the commented (hashed) bit a good idea - should I do
what i'm thinking of doing in the commented field.

5). do you have any suggestions??

here is the code:

from django.db import models, datetime

# Models for Resource Request Form.
CHK_APP_CHOICES = (
('STA', 'Simon Abbey''),
('JK', 'James Kong'),
('SF', 'Stavros Flatley'),
)

class RrsForm(models.Model)

checking")
* chk_date_dev = models.CharField("reason for any deviation check
date", max_length=200)
des_output = models.CharField("desired format of output: eg formal/
informal document, email, verbal, meeting, other (specify)",
max_length=200)
exp_date_final = models.DateField("expected release date for final
document")
* act_date_final = models.DateField("actual release date for final
document")
* fin_date_dev = models.CharField("reason for any deviation for
final document", max_length=200)
* document_num_loc = models.CharField("path of file on work server",
max_length=200)
# document saved to area on webserver as well
* upload_doc = models.FileField(upload_to'documents')
* comments = models.TextField()
* rel_prev_work = models.TextField("related to previous work")
* keywords = models.TextField()

def __unicode__(self):
return (self.project_and_task, self.project_number,
self.date_created, self.requested_by)

# may change requested_by to:
# requested_by = models.ForeignKey(Person)
#
## and then add a Person class after the RrsForm class?
#
#class Person(models.Model)
# first_name = models.CharField(max_length=50)
# last_name = models.CharField(max_length=50)

How about ...

project_homepage = models.URLField('Project Homepage', blank=True,
verify_exists=(not settings.DEBUG))

... which should avoid verification during development but make it
happen in production.

It's not covered in Django's documentation because it's a standard
feature of the Python programming language -- this is basic Python
string formatting, which follows similar conventions to printf()-style
formatting in other languages.

Deverifying a URLField

2012-01-24T15:30:00.001-08:00

Hello, all!

I have a small conundrum I could use a hand with.

I have a deployed Django application with a Model which has a
URLField:

project_homepage = models.URLField('Project Homepage', blank=True)

and a ModelForm to create the parent object.

Currently, the application checks to see if this is a valid URL. I
would like this to be unvalidated instead.

How do I go about changing it? Will I need to do a database migration
to do this? Or can I just add a 'verified=False' and run syncdb?

Thanks so much!

2012-01-24T15:04:00.001-08:00

Hi,

in the django docs about __unicode__ it says the following:

class Person(models.Model):
first_name = models.CharField(max_length=50)
last_name = models.CharField(max_length=50)

def __unicode__(self):
return u'%s %s' % (self.first_name, self.last_name)

what does the u'%s %s' % mean... I cannot find any exaplanation of
this in the docs?

i've seen this in someones code that was kindly lent to me by one of
the RC chat room people:

return u'ID%s: %s - %s - %s - %s' % (self.id, self.user,
self.question, self.answer, self.get_status_display())

but all this u' %s %s' %%%sss or what ever is most confusing....

is there a document or help guide some where that explains this
nomenclature, or method, system???

as I believe if you take the top example you should be able to do:
def __unicode__(self):
return(self.first_name, self.last_name)

If there is no documentation (for dummies) can anyone explain it to
me??

Re: I need help with Python Tools for Visual Studio 2010 and Django

Sam Lai,

Thank you so much for taking the time to explain all that to me.

Being new to all this I feel that I might need to just start out with a command prompt working with Django and something else... another command prompt or VS to create my python files.

However, having read what you posted, would you be able to give me some other options I can use for working with Python?

I know that's a general question and I'm sorry it's asking a lot but to me I see it like this. There is CPython and IronPython. I was under the impression they are both are interpreters. Atleast that's what I read right now. So I suppose I could move over to CPython and use that as my development realm for my Python?

I'm also tempted to trying to instal UNIX/LINUX because I keep seeing lots of videos on youtube where people seem to flawlessly be commanding their Python.

A lot to respond too I know, any help would be fantastic!

Re: Help Me With This Form

2012-01-24T12:07:00.000-08:00

Your view doesn't pass a context to the template. It needs to do this,
and your form needs to be part of the context.

something like:

from myweb.meekapp.models import mobForm
from django.shortcuts import render_to_response
from django.template import RequestContext

def home(request):
return render_to_response('home.html', {'mobForm': mobForm},
context_instance=RequestContext(requeoust))

The RequestContext bit lets you access information about the HTTP
request from inside your template. Not strictly necessary in this case,
but it's a good habit to get into. You never know when you're going to
want to know where the user was referred from, or what browser they're
using, for instance.

Cheers,
Cliff

Re: CsrfViewMiddleware from a xml post?

Hahaha, ya I saw that. I was hoping that it could just be inserted

That would be mandatory if one was going to be utilizing user post
data frequently however.

For what it's worth, I simply used this instead -->

<form id="vote" action="/votingConfirm/" method="post">{% csrf_token %}
<input name="person" type="text">
</form>

function confirmation(person) {
var answer = confirm('You are about to cast your vote for '+person)
if ( answer )
{
var submitForm = document.getElementById("vote");
document.body.appendChild(submitForm);
var element = document.getElementById("vote");
element.person.value = person;
element.submit();

Django made it easy for you! There's a javascript snippet you can
copy/paste that takes care of including the csrf token:

CsrfViewMiddleware from a xml post?

2012-01-24T07:47:00.001-08:00

Hey Gang, is it possible to include a csrf token with a xml post?
It looks like there are options in the view to control this but
getting into the header would be nice.

This isn't working along with many other tries. Anyone know what the
header should look like this offhand?

xmlhttp.open("POST","/votingConfirm/",true);
xmlhttp.setRequestHeader("X-CSRFToken",
$("#csrfmiddlewaretoken").val());
xmlhttp.send("person="+person);

Thanks

Help Me With This Form

2012-01-24T05:32:00.001-08:00

Hi guys, I'm trying to let this form display but it's not displaying
in my browser. When I open up the browser, only a blank page shows up.
How can I go about it? Below are my codes:

In models.py
from django.db import models
from django.forms import ModelForm, Textarea, HiddenInput
from django.contrib.auth.models import User
from string import join
from settings import MEDIA_ROOT
class group(models.Model):
desc=models.TextField(max_length=25)

def __unicode__(self):
return unicode(self.id)

def get_absolute_url(self):
return "/g/%s" % unicode(self.id)

class Admin:
list_display=('id','desc')
class Meta:
ordering=['-id']

class mob (models.Model):
author=models.ForeignKey(User,blank=True, null=True)
state_province=models.CharField(max_length=50)
body=models.TextField(max_length=10000)
date=models.DateTimeField('Date')
group=models.ForeignKey(group)

def __unicode__(self):
return u"%s - %s - %s - %s" % (self.author,
self.state_province, self.body, self.date)

def get_absolute_url(self):
return "/post/%s/" % unicode(self.id)
def get_author_url(self):
return "/u/%s/p/0" % (self.author)

class Admin:
list_display=('author','body','date')
date_hierarchy='date'
class Meta:
ordering=['-date']

class mobForm(ModelForm):
class Meta:
model=mob
fields=('body','author','state_province','date','group')
widgets={
'body':Textarea(attrs={"rows":2, "cols":40}),
'author': (HiddenInput),
'state_province': (HiddenInput),
'date':(HiddenInput),
'group': (HiddenInput),
}
class grpForm(ModelForm):
class Meta:
model=group
field=('desc')

In views.py

from myweb.meekapp.models import mobForm
from django.shortcuts import render_to_response
from django.http import HttpResponse
from django.template import RequestContext
from django.http import HttpResponseRedirect
from django.views.decorators.csrf import csrf_exempt
from django.contrib.auth.decorators import login_required
from django.contrib.auth.views import login, logout

def home(request):
return render_to_response('home.html')

in my template:

{% extends "base.html" %}

{% load pagination_tags %}

{% autopaginate object_list %}
{% block newsol %}
{% if user.is_authenticated %}
<div class="form">
<form action="." method="post" enctype="multipart/form-data">
<table>
{{ mobForm }}
</table>
<input type="submit" value="Update" />
</form>
</div>
{% endif %}
{% paginate %}
{% endblock newsol%}
How can I make the mobForm display? Thanks!

get_FOO_display() for generic/variable choice fields

2012-01-24T03:51:00.001-08:00

I have a model ContactDetail with two choice fields,
ContactDetail.dialing_code and ContactDetail.country. These use the
standard tuples ('AU', 'Australia') and so on.

I know I can use get_country_display() and get_dialing_code_display()
to show the longer values, but is there a more generic version where
the field name is replaced with a variable?

For example, I want to create a customised .csv file from the model
data. I can loop through the fields from my model and get the shorter
attribute values without any problems. However I'd like to do
something like this:

obj = queryset[my_item] # an instance of ContactDetail()
model = queryset.model # ContactDetail() itself

for field in model._meta.fields:
val = getattr(obj, field.name) # gets the shorter version
if field.choices: # if field is ChoiceField, convert data
to display mode
val = obj.get_field_display()
row.append(val)

Obviously the 'val = obj.get_field_display()' line doesn't work!

Is there a generic way of doing this (something like
obj.get_display(fieldname) ?) or am I going to have to hard code
separate checks for get_country_display() and
get_dialing_code_display()?

Ideally I would like to use this particular function for other models
and keep the fields as generic as possible.

Re: Selecting an E-commerce Application

2012-01-24T03:15:00.000-08:00

Thanks all, I decided to use plata for my project, since I feel it can be customized for my requirement much better than the other E-Commerce project (i might be wrong but still after evaluating most of the django ecommerce project this is what i felt). Matthias, thanks for developing Plata. Just starting the integration of Plata in my project and I hope you would lend some help if i get struck somewhere :) Thanks

Regards,

Thanks :-)

There is no stable release of Plata yet, but it is in use in several
shops right now, a few of them have been built by Feinheit, but I know
of two other companies which use it for their webshops.

The core hasn't changed much in months, and the basic ideas haven't
changed for even longer. I'd say even though there is no version 1.0
yet it is ready to build your shops on.

The current development version (https://github.com/matthiask/plata
branch master) comes without a product model -- the idea is that you
write your own because only you know which fields and which behavior
is needed. Models for contact information, discounts / vouchers,
carts, orders and payment tracking are included as are payment modules
for paypal, postfinance and cash-on-delivery. The checkout process is
fully managed by Plata, multi-currency shops are supported etc.

All of this means that yes, Plata isn't the best option if you want a
solution which works fine out of the box. If you anticipate you'll
have to customize the shop in several ways, choosing a lightweight
option with a small LOC count which solves the hard problems in a
reusable way (order tracking, payments, total calculation with taxes
and discounts), Plata might be the right choice for you.

Best regards
Matthias

Re: I need help with Python Tools for Visual Studio 2010 and Django

These 'Django commands' you're referring to, i.e. those involving
manage.py, are commands that are meant to be run from the command
prompt. You are executing a python script file, but they are not
Python commands.

VS doesn't work well outside of a VS project. Without one, it won't
know what your Python search path is, where all your code is located,
so you'll have minimal Intellisense (it'll know about the built-in
Python libraries, but not much else). You'll may also have issues
executing code because it doesn't know how to find all your code and
dependencies without the Python search path, and without that you'll
probably also lose the great debugging abilities of VS. All you're
really left with is a glorified syntax-checking text editor.

If you really want to do that, then the best solution is to open a
separate Command Prompt to run 'manage.py runserver' from. I mentioned
CPython before; that's just a name for the Python you download from
python.org. I used it to differentiate that from IronPython, which is
a .NET implementation of Python. I believe there are outstanding
issues with Django and IronPython, so it probably isn't worth trying
that.

You also seem to be confused with a Django project vs. a VS project. A
Django project simply defines the directory structure, and gives you a
few files to start with, including manage.py. This structure is how
Django is able to find the various files it needs.

A VS project is necessary to let VS know where all your files are,
where it should look for your Python packages etc. It is for VS to
know how to execute, debug and manage your code. Django does not know
anything about the VS project, and it shouldn't because it has nothing
to do with Django once Django is running.

Once you've created a VS Python Application project (ideally in the
same directory as your Django project), here's how to make it run the
built-in Django test server -

1. Right-click on your VS project in the Solution Explorer, and click
Properties.
2. Click on the Debug tab.
3. In 'Script Arguments', type 'runserver'.
4. Save the Project properties.
5. Add the files in your Django project to your project by
right-clicking on your VS project, Add, Existing item.
6. Right-click on manage.py and select 'Set as Startup File'.

To test, just go Debug -> Start Debugging or press F5.

I've had a quick play around; looks like the 'Execute project in
Python Interactive' option doesn't pass script arguments along, so
that won't work for running the test server, but then again, there's
nothing to interact with in the test server anyway. You can use that
option to test out models and the Django API though.

Re: retrieve model instance from database without model instance

2012-01-23T14:35:00.000-08:00

Check out the content types framework[1].

You can do something like:

ct = ContentType.objects.get(app_label='products', model='product')
obj = ct.get_object_for_this_type(name='Venezuelan Beaver Cheese')

However, as you can see in the example, you'll need to know the name of
the app so that Django knows where to find your model.

retrieve model instance from database without model instance

2012-01-23T13:15:00.001-08:00

How do I retrieve a model instance from the database without a model
instance?

For example from the doc[1] it has:
product = Product.objects.get(name='Venezuelan Beaver Cheese')

I want something like getInstance( 'Product', 'Venezuelan Beaver
Cheese' )

Here are the details of what I'm doing. I have multiple form models
that are all handled by the same post processing class. I'm using
django-celery to do the processing.

I want to do something like this in my view:
dbSave = form.save()
processTask.delay('Product', dbSave.pk)

Then in the task:
class processTask(Task):
def run(self, modelName, pk):
instance = getInstance( modelName, pk )
….

From what I've read about django-celery, I shouldn't pass class
instances to the task so I need a way to pass/retrieve this info via
basic datatypes.

Thanx for the answer. I´ll try the wikitools package.

Yes I knew I was in the Python shell I just never saw anything that described you couldn't make Django commands within the Python interpreter. I mean it is based on Python isn't it? That's where I thought logically you could make Django calls from in Python?

SO....

Is your best advice to have a OS prompt open in tandem with my Visual Studio Python Interpreter open? That being said that would be the best solution given my situation I suppose. However within the interpreter Python Tools for VS there may be limitations. That is what I've heard at least. I'm just referring to the interactive intellisense I think?..

Thank you for the tip on starting my server Andrew I will surely exit the Python interpreter and use a prompt!

Re: Why can't erase this model object? "AssertionError: Question object can't be deleted because its id attribute is set to None."

2012-01-23T10:30:00.000-08:00

I am a Django novice, so only a wild guess based on my Python knowledge...

Are you sure that you have 580 items in the container?
A Django program is to be executed at the web server side.
Therefore, it is desirable that the program does not crash
very easily. Search for the information on how the quests
is implemented. It is likely that it is not a "normal", strict
container that react by raising the exception. Returning
the special objects for the range outside the real data space
may be a good way to let you test further if the object really
exist. My guess is that you do not have that many object.
(But I may be completely wrong ;)

For sanity purposes I removed my "hack" or start up script that had "import django" and "import IPython"

Here it is:

>>> import sys

>>> sys.path

['c:\\Program Files (x86)\\Microsoft Visual Studio 10.0\\Common7\\IDE', 'C:\\Python27\\lib\\site-packages\\setuptools-0.6c11-py2.7.egg', 'C:\\Python27\\lib\\site-packages\\ipython-0.11-py2.7.egg', 'C:\\Python27\\lib\\site-packages\\django-1.3.1-py2.7.egg', 'C:\\Windows\\system32\\python27.zip', 'C:\\Python27\\DLLs', 'C:\\Python27\\lib', 'C:\\Python27\\lib\\plat-win', 'C:\\Python27\\lib\\lib-tk', 'C:\\Python27', 'C:\\Python27\\lib\\site-packages', 'c:\\Program Files (x86)\\Microsoft Visual Studio 10.0\\Common7\\IDE\\Extensions\\Microsoft\\Python Tools for Visual Studio\\1.1']

>>>

It looks like in both cases Django is included but I'm still not convinced that everything is right because in the windows command prompt I am able to start my server like a charm but in Visual Studio I don't think I can really do anything.

Are you not able to run Django commands from the Python prompt? That probably sounds stupid but to be honest I think the only time I can run Django commands is when I'm outside the Python interpreter in just the command prompt of Windows.

the >>> indicates you are IN a python shell, which is different from your OS prompt. Try exiting the shell first (with exit()) and then run "python manage.py runserver" from a command prompt or terminal window.

You've left out the most important bit - the actual traceback error. What is it?

If it can't find something, then it could be a PYTHONPATH issue.
Google tells me PT4VS may not support the usual way modules are
discovered (http://pytools.codeplex.com/discussions/254602), although
that should affect IronPython only, and not CPython (possibly
intellisense as well).

Inside PT4VS, in the interactive window, type in the following and
paste the result -

import sys
print sys.path

I'm not too familiar with these things yet. Are you saying CPython might be better if I want to work in Visual Studio with the setup I am trying?

Here is the response to

import sys
print sys.path

it is:

>>> import sys

...

>>> print sys.path

This smells like a hack. Your default working directory should already
be the directory your app is in. If it isn't, you need to check your
project settings (you are using a Python VS project right?).

Well I have no idea how I am hacking here...

But I didin't start a new project just through visual studio. I had already within the cmd prompt run the "startproject" command naming "mysite" to be "newartists." That was done at an earlier time so I just wanted to move to that directory within the python interpreter....

Well I didn't use a Python VS project because the files were already created but if I start a new Python file I'll most likely just pick my options within Visual Studio. That would make the most sense.

Thanks,
