在 Django 管理中创建新的自定义视图

Question

抱歉，我还是 Django 的新手。我想在管理站点上创建与我的模型无关的自定义视图。我已阅读文档（https://docs.djangoproject.com/en/2.0/ref/contrib/admin/#django.contrib.admin.ModelAdmin.get_urls），但不起作用。阅读一些教程也不起作用......这是我尝试过的：

管理文件

from django.contrib import admin
from django.urls import path
from .models import Question
from django.http import HttpResponse

class CustomAdminView(admin.ModelAdmin):
    def get_urls(self):
        urls = super().get_urls()
        my_urls = [
            path(r'^my_view/$', self.admin_site.admin_view(self.my_view))
        ]
        urls = my_urls + urls
        return urls


    def my_view(self, request):
        return HttpResponse("Hello, world.")


admin.site.register(Question)

网址.py

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

admin.autodiscover()
urlpatterns = [
    path(r'polls/',include('polls.urls')),
    path('admin/', admin.site.urls),
]

当我去 admin/my_view 时，结果是 404 not found。

我也尝试过扩展 AdminView。

管理文件

from django.contrib.admin import AdminSite
from django.urls import path
from .models import Question
from django.http import HttpResponse

class CustomAdminView(AdminSite):
    def get_urls(self):
        urls = super().get_urls()
        my_urls = [
            path(r'my_view/', self.admin_view(self.my_view))
        ]
        urls = my_urls + urls
        return urls


    def my_view(self, request):
        return HttpResponse("Hello, world.")


custom_admin = CustomAdminView()
custom_admin.register(Question)

网址.py

from django.contrib import admin
from django.urls import path
from django.conf.urls import include, url
from polls.admin import custom_admin

admin.autodiscover()
urlpatterns = [
    path(r'polls/',include('polls.urls')),
    path('admin/', custom_admin.urls),
]

我在 admin/my_view 上没有收到 404 错误。但是，不显示默认模型（用户和其他人）。那里只有我的“问题”模型。前一个仍然具有默认模型。

如何以正确的方式制作自定义管理视图？谢谢。

Answer 1

解决了。我正在使用我的第二个 admin.py 和 urls.py 片段并注册 django 的默认模型，基于这个答案：Django (1.10) override AdminSite

管理员.py

from django.contrib.admin import AdminSite
from django.http import HttpResponse
from django.urls import path
from .models import Question
from django.contrib.auth.models import Group, User #add these moduls
from django.contrib.auth.admin import GroupAdmin, UserAdmin #and these

class CustomAdminView(AdminSite):
    def get_urls(self):
        urls = super().get_urls()
        my_urls = [
            path(r'my_view/', self.admin_view(self.my_view))
        ]
        urls = my_urls + urls
        return urls


    def my_view(self, request):
        return HttpResponse("Hello, world.")


custom_admin = CustomAdminView()
custom_admin.register(Question)

#register the default model

custom_admin.register(Group, GroupAdmin)
custom_admin.register(User, UserAdmin)
