如何修复 "Page not found (404)" 错误 ("Django tried these URL patterns... The empty path didn't match any of these.")

Question

作为Django的新手，我遇到了和之前很多人一样的问题。如果您没有立即将我的问题标记为双重问题，我将不胜感激，因为我检查了那些旧帖子建议的修复但无济于事。

我正在关注 this tutorial and have finished with all up to the heading "Projects App: Templates". Now when I start the server, at http://localhost:8000/ 我得到：

Page not found (404) Request Method: GET Request URL: http://localhost:8000/

Using the URLconf defined in personal_portfolio.urls, Django tried these URL patterns, in this order:
admin/
projects/
The empty path didn't match any of these.

You're seeing this error because you have DEBUG = True in your Django settings file. Change that to False, and Django will display a standard 404 page.

这是我运行服务器时的控制台输出：

System check identified no issues (0 silenced).

Django version 2.2, using settings 'personal_portfolio.settings'

Starting development server at http://127.0.0.1:8000/

Quit the server with CTRL-BREAK.

Not Found: /

[05/Apr/2019 15:32:01] "GET / HTTP/1.1" 404 2042

Not Found: /favicon.ico

[05/Apr/2019 15:32:01] "GET /favicon.ico HTTP/1.1" 404 2093

我尝试过但没有帮助的方法：

正在重启服务器，
根据教程的 source code、
确保 'projects' 在 settings.py 的 INSTALLED_APPS 列表中。

这是 urls.py 里面的 rp-portfolio\personal_portfolio:

from django.contrib import admin
from django.urls import path, include

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

这是 rp-portfolio\projects 里面的 urls.py：

from django.urls import path
from . import views

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

Answer 1

在urls.py

from django.urls import path
from django.views.generic import RedirectView

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

Answer 2

试试这个

在urls.py

from django.contrib import admin
from django.urls import path, include

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

Answer 3

当您在项目中寻找路径时，您请求的路径必须是这个 http://localhost:8000/projects/

Answer 4

您需要添加：

in polls/urls.py

添加：from django.conf.urls import url

所以它应该看起来像：

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

urlpatterns = [
    path('', views.index, name='index'),
]

Answer 5

有时 URL 会从终端获取其他单词。

示例 1.0

在 http://127.0.0.1:8000/Quit 使用 CTRL-BREAK 的服务器启动开发服务器。

例如在示例 1.0 中，而不是像 http://127.0.0.1:8000/

这样打开 link

link 将是 http://127.0.0.1:8000/Quit，因为 /Quit 未包含在您的代码中，您将收到 404 错误。

示例 2.0

Starting development server at http://127.0.0.1:8000/
Quit the server with 
CTRL-BREAK.
Not Found: /Quit
[27/May/2021 22:36:07] "GET /Quit HTTP/1.1" 404 2066
[27/May/2021 22:36:59] "GET / HTTP/1.1" 200 5873
[27/May/2021 22:37:04] "GET / HTTP/1.1" 200 5873

希望这对您有所帮助。
