Django - 在自定义的AdminSite中注册应用程序模型

Question

我有一个Django项目，其中包含三个应用程序：website、blog和customauth。customauth应用程序实现了自定义用户和AdminSite。blog应用程序具有Post模型。我正在尝试在自定义的AdminSite中注册Post模型，但是我收到以下错误：

NoReverseMatch at /my_admin/
Reverse for 'app_list' with keyword arguments '{'app_label': 'blog'}' not found. 1 pattern(s) tried: ['admin\\/(?P<app_label>customauth)/$']
Request Method: GET
Request URL:    http://127.0.0.1:8000/my_admin/
Django Version: 2.0.4
Exception Type: NoReverseMatch
Exception Value:    
Reverse for 'app_list' with keyword arguments '{'app_label': 'blog'}' not found. 1 pattern(s) tried: ['admin\\/(?P<app_label>customauth)/$']

这是customauth/admin.py文件：

class MyAdminSite(admin.AdminSite):
    site_title = "Custom Administration Area"
    site_header = 'Custom Administration Area'

    def get_urls(self):
        urls = super(MyAdminSite, self).get_urls()
        my_urls = [
            url(r'^my_view/$', self.my_view, name='my_view'),
        ]
        return my_urls + urls

    def my_view(self,request):
        value = "You're looking at the new admin view."
        context = dict(
           # Include common variables for rendering the admin template.
           self.each_context(request),
           # Anything else you want in the context...
           key=value,
        )
        return TemplateResponse(request, "website/admin.html", context)

admin_site = MyAdminSite(name='myadmin')
# Now register the new UserAdmin...
admin_site.register(MyUser, UserAdmin)

以下是blog/admin.py文件:

from django.contrib import admin    
from customauth.admin import admin_site
# Register your models here.
from .models import Post

class PostAdmin(admin.ModelAdmin):
    pass

admin_site.register(Post,PostAdmin)

这里是网站/urls.py文件：

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

from . import views

urlpatterns = [
    path('admin/',       admin.site.urls,            name='admin'),
    path('my_admin/',    include('customauth.urls'), name='custom_admin'),
    path('',             views.index,                name='index'),
    path('latest_news/', include('blog.urls'),       name='latest_news')
]

这里是customauth/urls.py文件：

from . import views
from .admin import admin_site

urlpatterns = [
    path('', admin_site.my_view, name='custom_admin'),
]

我做错了什么？

我在从Django文档中复制粘贴时遇到了一些NoReverseMatch错误的问题。你写的那行代码应该是self.each_context(request)，而不是self.admin_site.each_context(request)。谢谢！ - undefined

Answer 1

我发现了我的错误。

问题出在我配置的URL方式上。

在website.urls中，我改变了：

path('my_admin/',    include('customauth.urls'), name='custom_admin'),

到

path('my_admin/',    admin_site.urls,      name='custom_admin'),

这解决了问题。我不再需要customauth.urls文件。
