Django 管理员/ return 404

Question

启动开发服务器

未找到：/admin/ [30/May/2021 20:33:56] "GET /admin/ HTTP/1.1" 404 2097

project/urls.py

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

urlpatterns = [
        path('', include('marketability.mkbl_urls')),
        path('admin/', admin.site.urls),
        path(r'^ckeditor/', include('ckeditor_uploader.urls')),
    ]

变体 path(r'admin/', admin.site.urls), 和 path(r'^admin/', admin.site.urls), 也不起作用。

superuser 已创建

因此，我没有发现与 Django 文档有任何差异。如何解决？谢谢

Answer 1

你的路径：

path('<<b>slug:cat_</b>>/', views.page_Category_Main, name='cat'),

将与 admin/ 匹配，因此将 admin 视为 cat_ slug 的值，从而触发该视图。该路径的视图可能会尝试获取带有 admin 作为 slug 的元素，但未能执行此操作，从而引发 HTTP 404 响应。

您可以将 admin/ 和 ckeditor/ 的 url 放在您的类别之前：

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

urlpatterns = [
    <b>path('admin/', admin.site.urls)</b>,
    <b>path('ckeditor/', include('ckeditor_uploader.urls'))</b>,
    path('', include('marketability.mkbl_urls')),
]

Django 将自上而下地访问 url 模式，从而触发第一个匹配的路径模式，在这种情况下是管理员。

然而，最好也为您的 marketability url 添加前缀，例如：

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

urlpatterns = [
    path('admin/', admin.site.urls),
    path('ckeditor/', include('ckeditor_uploader.urls')),
    path(<b>'market/'</b>, include('marketability.mkbl_urls')),
]

否则不可能有一个名为admin的类别。
