Django：无法使 urls.py 工作

Question

Django 初学者，抱歉：

我的项目urls.py：

from django.conf.urls import include, url
from django.contrib import admin
from django.conf import settings
from django.conf.urls.static import static
import profiles.urls
import listings.urls
import accounts.urls
from . import views

urlpatterns = [
    url(r'^$', views.HomePage.as_view(), name='home'),
    url(r'^about/$', views.AboutPage.as_view(), name='about'),
    url(r'^users/', include(profiles.urls, namespace='profiles')),
    url(r'^admin/', include(admin.site.urls)),
    url(r'^', include(accounts.urls, namespace='accounts')),
    url(r'^listings/', include(listings.urls)),
]

我的应用程序 urls.py：

from django.conf.urls import url
from . import views

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

http://localhost:8000/listings 给我一个错误 "The localhost page isn’t working. localhost didn’t send any data."

我不知道这里出了什么问题，我就是无法正常工作。有什么想法吗？

Answer 1

你必须在正则表达式的末尾加上“$”，像这样

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

在您的项目中 url：不要使用导入

url(r'^listings/', include('listings.urls')),

Answer 2

错误在我的 views.py 中。我用 Listing.all() 而不是 Listing.objects.all()。
