为什么我在 Django 的 URL 模式中收到“找不到页面”错误？
[英]Why am I getting a 'Page Not Found' error in Django's URL patterns?
问题描述
I'm new to Django and I'm just trying to create a small application to output 'Hello World'.
我是 Django 的新手，我只是想创建一个小应用程序来输出“Hello World”。 When I run my code, it says 'Page not found' and gives me the following reason:当我运行我的代码时，它显示“找不到页面”并给出以下原因：
'Using the URLconf defined in helloworld_project.urls, Django tried these URL patterns, in this order:
admin/
home/
The empty path didn't match any of these.'
I'm a bit confused as to why this is happening.我有点困惑为什么会这样。 I've included a few samples of my code.我已经包含了我的代码的一些示例。 Any assistance would be greatly appreciated!任何帮助将不胜感激！
urls.py网址.py
from django.contrib import admin
from django.urls import path
from my_app.views import HomeView
urlpatterns = [
path('admin/', admin.site.urls),
path('home/', HomeView.as_view())
]
views.py视图.py

If you're running Django in the port for example 8000, the url:如果您在端口（例如 8000）中运行 Django，则 url：
localhost:8000/
is the empty pattern url.是空模式网址。
according to your URLs definitions you've to:根据您的 URL 定义，您必须：
localhost:8000/home/
or change your url to:或将您的网址更改为：
urlpatterns = [
path('admin/', admin.site.urls),
path('^$', HomeView.as_view()) # Point the empty pattern to your view.
]

You need to change your url like:您需要更改您的网址，例如：
urlpatterns = [
path('', someview),
path('admin/', include(admin.site.urls) ),
path('home/', HomeView.as_view(), name='somename')
]
The error is obtained because when you run your project, it looks for an empty url like localhost:8000/ instead of localhost:8000/home/ .之所以会出现该错误，是因为当您运行项目时，它会查找一个空 url，如localhost:8000/而不是localhost:8000/home/ 。
