空路径与任何这些都不匹配(django) [英] The empty path didn't match any of these (django)

问题描述

在>空路径没有匹配其中任何一个.当我在 personal_portfolio.py 中包含 path(''，include('projects.urls'))时，该解决方案确实有效.但这是我的烦恼...

A similar question was asked here in The empty path didn't match any of these. The solution did indeed work when I included the path('',include('projects.urls')) within personal_portfolio.py. But here's what bugs ME...

personal_portfolio/urls.py:

personal_portfolio/urls.py:

urlpatterns = [
path('admin/', admin.site.urls),
path('projects/', include('projects.urls')),
]

projects/urls.py:

projects/urls.py:

urlpatterns = [
path("", views.project_index, name="project_index"),
path("<int:pk>", views.project_detail, name="project_detail"),
]

包含空路径(在后者中)！调用 path('projects/'，include('projects.urls'))时，应调用 projects/urls.py .

The empty path IS contained (in the latter)! when the path('projects/', include('projects.urls')) is called, it should call projects/urls.py.

然后 有空路径.为什么我需要在 personal_portfolio/urls.py 中包含 path("，include('projects.urls'))才能起作用?！

Then the empty path is there. Why do I need to include path("",include('projects.urls')) in personal_portfolio/urls.py for it to work?!

推荐答案

path("，...)包含在 path('projects/'，include('projects.urls'))，因此路径为:

path("", ...) is included by path('projects/', include('projects.urls')), therefore the path is:

'projects/' + "" = "projects/"

因此，您需要访问 localhost:8000/projects/，对 localhost:8000/的请求将失败.

Therefore you need to access localhost:8000/projects/ and a request to localhost:8000/ will fail.

如果您使用 path("，而是使用include('projects.urls'))，则路径为:

If you use path("", include('projects.urls')) instead, then the path is:

 "" + "" = ""

现在，对空路径 localhost:8000/的请求将成功.

Now a request to the empty path localhost:8000/ will succeed.
