我得到错误：
页面未找到（404）GET请求URL：http://localhost:8001/使用recipe_organizer. urls中定义的URLconf，Django尝试了以下URL模式，顺序如下：^admin/^ recipes/^ media/（？P. *）$当前的URL，，与其中任何一个都不匹配。
不久前还在工作，但不是什么都不会发布。
下面是我的www.example.com文件：urls.py file:

from django.conf.urls import include, url
from django.contrib import admin
from django.conf import settings

urlpatterns = [
    url(r'^admin/', include(admin.site.urls)),
    url(r'^recipes/', include('apps.recipes.urls')),
    url(r'^media/(?P<path>.*)$', 'django.views.static.serve', {'document_root': settings.MEDIA_ROOT}),
]

以下是我的设置（不包括特殊键）：
