Django - Strange behavior using static files

Question

I'm new to Django. I'm getting insane trying to understand what is going on with static files(css's and images).

The resume of the problem is the following... when I use static views from a 3rd party App(Haystack) I can't use static files.

My project have this directory structure:

1001empbr (name of the folder for the project)
   |
   |------ 1001emp (name of the django project)
              |
              |------ 1001empbr (name of my App)
              |------ site_media (folder with static files CSS/JPG/GIF)
              |------ templates (folder with the templates)

When I use urlpatterns(urls.py) like this works great:

import os.path # Para poder suportar static files
from django.conf.urls.defaults import patterns, include, url
from emp1001br.views import *
from emp1001 import settings
from haystack.forms import FacetedSearchForm
from haystack.query import SearchQuerySet
from haystack.views import FacetedSearchView
import datetime

urlpatterns = patterns(
    #'haystack.views',                   
    #url(r'^resultados/$', FacetedSearchView(template='emp1001br/pgresultados.html', searchqueryset=sqs, form_class=FacetedSearchForm), name='haystack_search'),                 
    '',
    (r'^site_media/(?P<path>.*)$', 'django.views.static.serve', {'document_root': settings.MEDIA_ROOT}), # To support static files
    url(r'^$', main_page),
    (r'^iframe/$', i_frame),
)

Here is the server activity:

When I use with the static views from Haystack:

import os.path # Para poder suportar static files
from django.conf.urls.defaults import patterns, include, url
from emp1001br.views import *
from emp1001 import settings
from haystack.forms import FacetedSearchForm
from haystack.query import SearchQuerySet
from haystack.views import FacetedSearchView
import datetime

urlpatterns = patterns(
    'haystack.views',                   
    url(r'^resultados/$', FacetedSearchView(template='emp1001br/pgresultados.html', searchqueryset=sqs, form_class=FacetedSearchForm), name='haystack_search'),                 
    '',
    (r'^site_media/(?P<path>.*)$', 'django.views.static.serve', {'document_root': settings.MEDIA_ROOT}), # To support static files
    url(r'^$', main_page),
    (r'^iframe/$', i_frame),
)

Some after time browsing I get this:

Any clue about what should be causing this?

Best Regards,

That has absolutely nothing to do with static files (which you aren't using correctly anyways). I think you need to revise your question to make it more clear what you're trying to accomplish. — Chris Pratt, Nov 17 '11 at 18:13
Thanks for your reply. Can you give me a clue about the subject of the problem? I'm very few experiene with Django. — André, Nov 17 '11 at 18:31
If you're using apache try `SetHandler none` at site_media directory — Guilherme David da Costa, Nov 18 '11 at 13:10

I don't know whether this will fix the issue, but your url patterns look a little confused. Each urlpatterns object should only have one prefix string as its first argument. You have 'haystack.views' and then later ''.

You are passing callable objects instead of strings in your url patterns, so using the empty string '' for your prefix is fine.

urlpatterns = patterns(
    '',                   
    url(r'^resultados/$', FacetedSearchView(template='emp1001br/pgresultados.html', searchqueryset=sqs, form_class=FacetedSearchForm), name='haystack_search'),                 
    (r'^site_media/(?P<path>.*)$', 'django.views.static.serve', {'document_root': settings.MEDIA_ROOT}), # To support static files
    url(r'^$', main_page),
    (r'^iframe/$', i_frame),
)

Nice solution, I just passed my eyes real quick and didn't saw the prefix problem. — Guilherme David da Costa, Nov 18 '11 at 13:08
