在網站上運行Django服務器時出現404錯誤

Question

我得到錯誤：

找不到頁面（404）請求方法：GET請求URL： http：// localhost：8001 / Django使用recipe_organizer.urls中定義的URLconf，按以下順序嘗試了這些URL模式：^ admin / ^ recipes / ^ media /（ ？P。*）$當前URL與此不匹配。

不久前它就開始工作了，但不會發布任何消息。

這是我的urls.py文件：

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}),
]

這是我的設置（不包括特殊鍵）：

有人有什么想法嗎？ 將不勝感激。

Answer 1

您可以訪問http：// localhost：8001 / admin /嗎？

如果是，那么問題很簡單，就是您尚未為根http：// localhost：8001 /定義URL條目。

就像是：

url（r'^ $'，views.index，name ='index'），

應該可以。

不要忘記在views.py中定義索引
