的Django總是給404

Question

我的Django項目總是給我一個404，不管我想訪問的頁面。作爲一個Django noob，我不知道如何解決這個問題。有什麼建議麼？

編輯：這是我的urls.py：

from django.conf.urls.defaults import * 

# Uncomment the next two lines to enable the admin: 
# from django.contrib import admin 
# admin.autodiscover() 

urlpatterns = patterns('', 
    # Example: 
    # (r'^mcifdjango/', include('mcifdjango.foo.urls')), 

    # Uncomment the admin/doc line below to enable admin documentation: 
    # (r'^admin/doc/', include('django.contrib.admindocs.urls')), 

    # Uncomment the next line to enable the admin: 
    # (r'^admin/', include(admin.site.urls)), 
) 

Answer 1

您必須在urls.py中包含從urls到視圖的映射。欲瞭解更多信息：

Answer 2

什麼樣的行爲是你期待？

你沒有映射到任何東西 - 你應該只得到404s！

import http 

def a_view(request): 
    return http.HttpResponse("My first mapped url") 

urlpatterns = patterns('', 
    (r'^$', a_view), # my first url mapped to anything 
    (r'^second_url/$', a_view), # my second non 404 url 
)
