You'll need to configure your webserver to manage this, with some sort of 
URL rewriting - eg RewriteRule in Apache, or whatever the equivalent is in 
whatever you are using.

How do you check that user is logged in ? If it's via request.user,
then it doesn't work 'cause you
aren't passing the request object to your template's context. The
recomended way to do this is using RequestContext:

from django.template import RequestContext

return render_to_response('forms/contact.html', {'form': form},

Re: Multi widget?

[Sam Walters]

Hi,

I think you are looking to override the widget render() method to
build multiple HTML form elements?
Here is a good example:

http://k0001.wordpress.com/2007/11/15/dual-password-field-with-django/

I have built heaps of these things, usually a choicefield + charfield,
charfield + charfield, charfield + datefield etc. Anything where you
want to be able to call clean() on multiple form elements because they
have some sort of interdependant logic.

Also for doing this looking directly at the django source code in
forms, fields and widgets is the best way to understand how it works.


cheers

How configure Django to handle /books URL and yet allow access to PDFs/images in subdirs of /books?

[Chris Seberino]

How configure Django to handle /books URL and yet allow access to PDFs
and images in subdirs of /books?

Specifically, I want /books to be a dynamic page with lots of links to
PDFs and images of book covers contained in subdirectories of /books
like /books/some_book_1 and /books/some_book_1/book_cover.jpg.

Contact form doesn't see user as logged in

[Catalyst]

 I am having trouble with a contact form on my site. Whenever I hit
the page, it doesn't see that the user is logged in. Here's how my
code looks.


#forms.py

from django import forms
from django.utils.translation import ungettext, ugettext_lazy as _

class ContactForm(forms.Form):
subject = forms.CharField()
email = forms.EmailField(required=False)
message =
forms.CharField(widget=forms.Textarea(attrs={'rows':'20',
'cols':'75'}))




#urls.py
from django.conf.urls.defaults import *

urlpatterns = patterns('myproject.forms.views',
(r'^contact-us/$', 'contact'),
)




#views.py

from django.core.mail import send_mail
from django.http import HttpResponseRedirect
from django.shortcuts import render_to_response
from myproject.forms.forms import ContactForm

def contact(request):
if request.method == 'POST':
form = ContactForm(request.POST)
if form.is_valid():
cd = form.cleaned_data
send_mail(
cd['subject'],
cd['message']+'\nUser email '+cd['email'],
('formemailaddr...@email.com'),
['sendaddr...@email.com'],
)
return HttpResponseRedirect('/forms/thanks/')
else:
form = ContactForm()
return render_to_response('forms/contact.html', {'form': form})



  If I hit another page, the user still shows up as being logged in,
just this one area (the contact form) doesn't. Even the thank you page
shows the user as being logged in.

  Anyone have any ideas?

Solved: Re: Still mystified by [not a] mod_wsgi traceback ...

[Stephen Waterbury]

Ach, permissions problem.  After I disabled the error message in
d.c.a.m.RemoteUserMiddleware, I got an error message about the
database not being writable -- I'm using sqlite and forgot that
the *directory* containing the db file has to be writable (for the
temp file).  Doh!  So the real problem that the
d.c.a.m.AuthenticationMiddleware message got triggered by was that
the User it tried to create couldn't be saved (I infer) -- not a
very good error message for that!  (mod_wsgi works just fine! ;)

My set up:

':8000' virtual host, each with a separate wsgi script (of course)

Ultimately I'll be using Active Directory (Kerberos) auth, but for
purposes of testing the REMOTE_USER stuff I've configured Basic
Authentication, and it is working (I authenticate successfully
before seeing that error message).

Any suggestions welcome! (I can send the whole error page if it
would help, but I'll need to launder it a little.)

Can't use dumpdata and loaddata to migrate non-ASCII data between databases

[Eric Chamberlain]

Hi,

We are trying to migrate between databases and we are running into a problem 
while trying to use dumpdata.  We've tried:

./manage.py dumpdata --natural --indent 2 > dump.json

and:

./manage.py dumpdata --natural --format xml --indent 2 > dump.xml

Both return the following error:

Error: Unable to serialize database: 'ascii' codec can't encode 
character u'\xe9' in position 18: ordinal not in range(128)

Is there a way to dump and load non-ASCII data?

Bug when OR'ing an empty Q() with a non-empty Q()?

[Margie Roginski]

I find that if I filter by ORing an empty Q() with a non-empty Q()
that I don't get the expected result.  I would expect that this should
return all objects of the specified model that the empty Q() would
return.  Let me use an example to be more clear:

I have a single Task object with its name set to foo.

Task.objects.filter(Q()) gives me that one object:
[]

But:

Task.objects.filter(Q()|Q(name="bar"))

returns []

Is this a bug or am I misunderstanding something?  This is on Django
1.2.1

Thanks for any pointers,

Margie

Re: to execute executable.py from view.py

[gintare]

One more related question.

Is it possible to use string in views.py as a function ( string from
textarea (in search.html ))

i.e.
# search.html

 input function name 



this search.html after being registered in urls.py shows input text
area.
I prompt to write the name of function.

I get this name as string in views.py in function def
search2(request):
query=request.GET.get('q',' ' )
i would like now to run this function, which was written in textarea,
 i.e to run function Word.objects.all()

One of ways is to use Sqlite cursor and execute strings.
Another way is to use case type structure, which match function name
in string with function name in cases.

How to run this function, which was written in textarea as string,
without sqlite and case structures?

Re: Some problem with modelform save

[robos85]

THANKS. I overlooked it.

To work around this problem, every time you save a form using commit=False, 
Django adds a save_m2m() method to yourModelForm subclass. After you've 
manually saved the instance produced by the form, you can invoke save_m2m() to 
save the many-to-many form data.

I enthusiastically second this. If you're unfamiliar with pdb, check out this 
slice of awesome:

http://blog.doughellmann.com/2010/09/pymotw-pdb-interactive-debugger.html

Incidentally, the Python doc page has just a bit that's not in the tutorial. 
The only thing that springs to mind is the 'skip' argument, but you might want 
to skim it. The debugger is a fantastic tool to have in your toolbox.

Re: Django dev server issue

[Brian Bouterse]

Have you tried using pdb to debug the call as it arrives?  You could step
through the code, line by line that way to see what is hanging.

My 2 cents,

Re: Django dev server issue

I just tested with sock Python 2.6.6 from the link you gave me and

Some problem with modelform save

[robos85]

I use modelform. All works fine. Validation is ok and I want to save my 
form. Before saving I need to populate user_id into my modelform so i make 
something like this:
if form.is_valid():

obj = form.save(commit=False)

  obj.user = request.user
  obj.save()

It seems to be ok. Form is saved to DB BUT!: I use 
categories = models.ManyToManyField(Category)

When I use the method above - categories aren't saved into DB :(
When I do form.save() - categories are added but User object not :(

Am I something missing?

Re: Problem with validating ModelForm

I've written that part of form subclass:
def clean_title(self):
data = self.cleaned_data['title']
counter = Article.objects.filter(title__iexact = data).count()
if counter > 0:
raise forms.ValidationError('my message')
return data

Is that right?

Django, unobtrusive JavaScript and cross-site scripting

[Mo Mughrabi]

Hi,
am wondering if there is a manual/tutorial that talks about advance use
of JavaScripting and django, using existing frameworks such as JQuery or
Prototype, generating unobtrusive JavaScripting with no inline
Javascripting.

Another question, is there a place where I can read about cross-site
scripting and how I can protect my django project from such a thing?

Regards,

Re: Problem with validating ModelForm

[robos85]

Could You give me some frame, how it should be? I've never done it before:/
I have that added:
def clean_title(self):
data = self.cleaned_data['title']
return data
But how to check if that field is unique? Is there some special way, or just 
to write simple query to check it?

Re: Django dev server issue

[W. Craig Trader]

I'm currently developing on Windows 7 (64-bit) with stock Python 2.6.6
(32-bit) and Django 1.2.3, and having no problems when running the Django
development server from the command line.

I'd recommend using the normal Python (
http://www.python.org/download/releases/2.6.6/) instead of ActivePython and
see if that improves things.

Re: loading the external css file

[Chris Lawlor]

If you don't have a staticfiles module, you most likely aren't using
Django 1.3. Make sure you select the correct version of Django when
viewing the docs, as things are often done differently in older
versions, but the doc pages usually default to the latest SVN release.

Re: Django dev server issue

[daniels]

Hi,
Unfortunately i did not found the case, and i'm getting it pretty
often, about 3 out of 5 times i refresh the page.
If i leave it loading and i don't stop it it stays like that for about
30-40 seconds and then the page loads.
I just don't understand what is causing this.
I've restarted the server like 10 time or more from the first time i
got this and i'm still getting it every time i run it.

My Python version is : ActivePython 2.6.6.17 (ActiveState Software
Inc.) based on
Python 2.6.6 (r266:84292, Nov 24 2010, 09:16:51) [MSC v.1500 32 bit
(Intel)] on
win32

and Django: (1, 2, 3, 'final', 0)

I did a lot of dev on Windows 7 before but i never had this issue. So
my thoughts are that this is either
related to this Django version or Python version.

How to get URI in settings.py

How to get URI in settings.py

Reason for that is if URI is for admin to disable all languages in
settings.py
if there is no admin in URI to leave all languages.

Re: Templates Directory Question

[Daniel Hepper]

You can put the templates anywhere you want, by a good place is a
directory named templates in the base directory of your project, i.e.

C:\DjangoProjects\mysite\templates\

Don't forget to add this path to the TEMPLATE_DIRS variable in your settings.py.

The template file from the example would be placed at

C:\DjangoProjects\mysite\templates\polls\index.html

You can probably ignore the document root for now, but I'll try to
explain what it means.
The term "document root" refers to the directory that a webserver like
Apache uses to look for files.
Let's say the webserver running on example.com is configured with
document_root = C:\apache\htdocs. If you visit
http://example.com/foo.html, the webserver would serve you the file
C:\apache\htdocs\foo.html.
I hope that makes sense and doesn't add to the confusion.

Re: Django dev server issue

[Tiago Almeida]

Hi,

Your files seem fine, I believe.
Have you found the cause? What version of python and django are you
using? I also have this issue but it is not often enough for me to
worry too much. Killing the server and restarting it solves it for
me..

BR,

Problem with validating ModelForm

[robos85]

I use ModelForm to create my form. All works fine except 1 thing - 
validating the unique field.
Code:
class Article(models.Model):

...

title = models.CharField(max_length=255, unique=True, 
error_messages={'max_length' : 'max translation',
 
   'unique' : 'unique translation',
 
   'required' : 'req translation',})

...


class ArticleForm(ModelForm):

...

title = forms.CharField(max_length=255, min_length=3, 
error_messages={'required' : 'req translation',
 
'min_length' : 'min translation',
 
'max_length' : 'max translation',
 
'unique' : 'unique translation',}) 



But when I save my form with  non-unique title I don't get my custom 
translated error but I get default error. How to fix it, that my unique 
field error is displayed?

Re: Cant locate problem with trunk: 'ModelForm' object has no attribute '_meta'

[Martin]

> Could you please try again but rolling back your Django trunk  installation to

>

Hi Ramiro,

thank you for your help. It's funny cause I rolled back to 15000 to
check :/ . It works fine with 14991.
With trunk I was able to locate the error-cause down to a url tag of
my template. Hope it helps to solve this Django issue. Too deep for
me, but let me know if I can provide you with more information.

If I remove this from my template, everything is fine: {% url
profile_overview %}
Url is defined as following:
In my main urls.py:

urlpatterns+= patterns('',

(r'^account/', include('foo.pluggables.userprofile.urls')),

userprofile/urls.py:

urlpatterns = patterns('',
url(r'^profile/$', overview, name='profile_overview'),

The function overview can be empty, doesn't affect the error.

Hope that helps you somehow.

Templates Directory Question

[Anthony Pearce]

In Tutorial 2, I was instructed to make a templates directory. It is
located at:
 C:\DjangoProjects\mysite\templates

Now again in Tutorial 3, section "Write views that actually do
something", I am given the instructions:
  create a directory, somewhere on your filesystem, whose
contents Django can access. (Django runs as whatever user your server
runs.) Don't put them under your document root.


I think the document who's root I cannot put them under is the
views.py document, as that's what I had been editing.  It is located
at:
 C:\DjangoProjects\mysite\polls\views.py

I guess my question is, where is the best place for this new templates
directory?  Can I simply make a subdirectory in the templates
directory for the views.py template?  For example, like this:
 C:\DjangoProjects\mysite\templates\views\

Sorry for a question with likely a quite obvious solution, but thanks
again for any assistance.

Re: Unable to import middleware class 'facebook.djangofb.FacebookMiddleware' with uncaught exception

[PJ]

Yes, I believe I installed all the pre-reqs, though let me know if I
should check anything else:
from the console:
>>> import facebook
>>> import facebook.djangofb
>>>
I'm thinking perhaps it's running the wrong version of python? My
server had 2.4 alias'd as python, but I re-alias'd python2.6 as python
in my .profile, however a "which python" gives my nothing, even though
python -V says 2.6.

I think it is a bug, specifically this one:

Filter after annotate

[Maxim]

Hi,

I've come across a weird behavior, just wondering if it is a bug or a
feature.
My task is to group a list of actions by user, count the values sum
and filter them by absolute value. E.g.

user1  5
user1  10
user2  2
user3  -12

and limit = 10, I want to see

user1  15
user3  -12

Here's the snippet of my code:
Actions.objects.values("context_user").annotate(points =
Sum("value")).filter(Q(points__gt = limit) | Q(points__lt = -limit))

Note using OR in a filter. But to my surprise the SQL query looks
like:
... GROUP BY "action"."context_user_id" HAVING (SUM("action"."value")
> 0  AND SUM("action"."value") < 0 )

Somehow Django uses AND instead of OR, thus the result is always
empty.

Can anyone explain this behavior to me and point out the solution if
it's not a bug?

Thanks.

Forms would be a likely place where you will need to be using lazy
translation (
http://docs.djangoproject.com/en/dev/topics/i18n/internationalization/#lazy-translation).
If you are not, that may be the problem.

Re: Too many items in my drowndown list

[Greg Turner]

Using a raw_id_field instead of a dropdown list will open a popup with a
'pseudo' django admin. The reason I call it 'pseudo' is that the list can be
searched or filtered just like the normal django admin, but when you click
on an item, it becomes the selected item in your inline, and the window
closes.

Re: render_to_response

[Greg Turner]

Just have my_fnc return a dictionary (or other object), rather than the
whole rendered response:

def search(request):
..
   answ = my_fnc(roots)
   return render_to_response("my_fnc.html", { "answ" : answ['FindWord'] } )

def my_fnc( roots ):
   FindWord=authors.objects.filter("name"__contains=roots)
   return { "FindWord" : FindWord }

(A couple of style points:

   - PEP8 recommends avoiding CamelCase in favour of under_scores
   - In views.py, I lean towards naming functions that aren't views, (my_fnc
   in this case) with an underscore, such as _my_fnc)

)

Hope this helps,

Greg

Re: Too many items in my drowndown list

Hi,

for the admin interface you can use raw_id.

It helps if you post the full stack of the error - we can tell which 
line of code it came from then.  However,



def artist(request, myartist):
myArgs = Song.objects.all().filter(artist=myartist)
return render_to_response('music/index.html', {'artist': myArgs})


I think this is your problem.  What are you passing in on the url for 
myartist?  Is it a slug?


Song.objects.all().filter(artist=myartist)

is expecting myartist to be an Artist instance. Try

Song.objects.all().filter(artist__slug=myartist)

(that's two underscores between artist and slug.)

This says "Select me all the songs where the related Artist's slug is 
whatever was passed in on the url"


Hope that helps,

Tim.

Multi widget?

[robos85]

Hi,
what I want to do, is to add 2 widgets to 1 field. So far I have:

content = 
forms.CharField(widget=forms.Textarea(attrs={'class':'add_editor'}),)

But I also want to add some medi to it (tinymce .js files). How can I do 
that?

render_to_response

[gintare]

How formulate correctly the code below:

[code]
#views.py

def search(request):
..
answ = my_fnc(roots)
return render_to_response("my_fnc.html", { "answ" : answ } )

def  my_fnc( roots ):
FindWord=authors.objects.filter("name"__contains=roots)
return render_to_response("my_fnc.html", { " FindWord" :
FindWord } )

[code]

Gives error Manager isn't accessible via FindWord instances

I would like to get result of quesry in separate function.
How to return this result to initial function in view or print it to
*.html form from another function?

Problem with translations

[Isaac XxX]

Recently, i've found a problem with i18n translations in Django.

All my translations are located inside views functions, templates and some
of them are in a file called forms.py (where i store some of my forms).

The problem arise when I render that forms. First render time, seems that
locale is applied, but next times the same locale is displayed again,
without beign able to change it through locale selector. The rest of
translations are behaving correctly. Any clue about what's happening with
translations outside of views and templates files?

Thank you in advance

Isaac
