Django - Comportement étrange en utilisant des fichiers statiques

Question

Je suis nouveau sur Django. Je deviens fou en essayant de comprendre ce qui se passe avec les fichiers statiques (css et images).

Le résumé du problème est le suivant ... lorsque j'utilise des vues statiques d'une application tierce (Haystack) je ne peux pas utiliser de fichiers statiques.

Mon projet ont cette structure de répertoire:

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) 

Lorsque j'utilise urlpatterns (urls.py) comme celui-ci fonctionne très bien:

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), 
) 

Voici l'activité du serveur:

Lorsque j'utilise les vues statiques de 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

    r, w, e = select.select([self], [], [], poll_interval) 
AttributeError: 'NoneType' object has no attribute 'select' 

Toute idée de ce qui devrait être la cause?

Cordialement,

Je ne sais pas si cela va résoudre le problème, mais vos habitudes url regarder un peu confus. Chaque objet urlpatterns ne doit contenir qu'une seule chaîne prefix comme premier argument. Vous avez 'haystack.views' et plus tard ''.

Vous êtes passing callable objects instead of strings dans vos modèles d'URL, donc en utilisant la chaîne vide '' pour votre préfixe est bien.

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), 
)
