Django 管理员/返回 404

如何解决Django 管理员/返回 404

在 http://127.0.0.1:8000/ 启动开发服务器

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

项目/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/', 和 path(r'^admin/', 也不起作用。

project/marketability/mkbl_urls.py

from django.urls import path
from django.views.generic.base import RedirectView,TemplateView
from . import views

app_name = 'marketability'

handler404 = 'marketability.views.handler404'

urlpatterns = [
    path('',views.home,name="home"),path('<slug:cat_>/',views.page_Category_Main,name='cat'),path('<slug:cat_>/<slug:product_>',views.page_Product,name='product'),path('al_about.html',views.about,name="about"),path('al_home.html',path('search_all.html',views.search_all,name="doorway"),path('robots.txt',TemplateView.as_view(template_name="robots.txt",content_type="text/plain")),path('sitemap.xml',TemplateView.as_view(template_name="sitemap.xml",content_type="text/xml")),path('favicon.ico',RedirectView.as_view(url='/static/marketability/favicon.ico',permanent=True)),]

project/marketability/admin.py

# Register your models here.

admin.site.register(TxtHow)
admin.site.register(Txtratings)

superuser 已创建

所以，我没有看到与 Django 文档的任何偏差。 如何解决？ 谢谢

解决方法

您的路径：

path('<slug:cat_>/',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，但无法执行此操作，从而引发 HTTP 404 响应。

您可以将 admin/ 和 ckeditor/ 的网址放在您的类别之前：

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

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

Django 会从上到下访问 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。

不过，最好也为您的 marketability 网址添加前缀，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('market/',]

否则就不可能有名为 admin 的类别。
