Question

我是Django的新手。我疯狂地试图了解静态文件（css＆s和图像）发生了什么。

问题的恢复如下......当我使用来自第三方应用程序（Haystack）的静态视图时，我无法使用静态文件。

我的项目有这样的目录结构：

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)

当我使用这样的urlpatterns（urls.py）时效果很好：

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),
)

以下是服务器活动：

当我使用Haystack的静态视图时：

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),
)

一些浏览后我得到了这个：

有关应该导致此问题的任何线索？

最诚挚的问候，

我不知道这是否能解决问题，但你的网址模式看起来有点混乱。每个urlpatterns对象应该只有一个prefix字符串作为其第一个参数。您有'haystack.views'，然后是''。

您的网址格式为passing callable objects instead of strings，因此使用空字符串''作为前缀是可以的。

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),
)
