Question

我刚接触Django＆amp;我使用的是1.8.3版本。我在网址上遇到了麻烦。我到处寻找答案，找不到答案。无论我做什么，我都会收到“NameError”，当我没有收到错误时，我会得到index.html页面。

http://127.0.0.1:8000/＆amp; http://127.0.0.1:8000/questions将在模板目录中呈现index.html或抛出错误。

我希望http://127.0.0.1:8000/questions呈现home.html目录中的templates/questions和http://127.0.0.1:8000/呈现index.html中的templates/。

我在问题/ admin.py中注册了模型，并在MyProj / settings.py中安装了该应用程序。

有人可以告诉我我错过了什么吗？提前致谢！：）

Answer 1

您的网址格式index正在抓取所有网址。这意味着将忽略下面的任何网址模式。

url('^.*$', IndexView.as_view(), name='index'),

要仅匹配索引（即http://127.0.0.1:8000/），请将其更改为

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

请注意，我还在正则表达式中添加了r''前缀。在这种情况下它没有任何区别，但在你的正则表达式中使用它是一个好习惯。

Answer 2

在MyProj / urls.py

urlpatterns = [
    url(r'^admin/', include(admin.site.urls)),
    url('^$', IndexView.as_view(), name='index'),
    url(r'^questions$', views.home, name='home'),
]

questions / urls.py：

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

questions / views.py

def home(request):
    return render(request, "questions/home.html", {})
