Django admin 注册自己的路由

通过 admin.py 在 Django 后台注册自己的路由（对应自己的视图）

要在一个 app 里面的 admin.py 添加如下代码

# django2\apps\business\admin.py

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

from .models import *
from .views import index

# Register your models here.

class DummyModel(models.Model):
    class Meta:
        verbose_name = "自定义路由"
        verbose_name_plural = '自定义路由'
        app_label = 'business'

def my_custom_view(request):
    return HttpResponse('自定义路由，写自己的内容')

class DummyModelAdmin(admin.ModelAdmin):
    model = DummyModel

    def get_urls(self):
        view_name = '{}_{}_changelist'.format(
            self.model._meta.app_label, self.model._meta.model_name)
        return [
            path('settings/', my_custom_view, name=view_name),
        ]

admin.site.register(DummyModel, DummyModelAdmin)

__init__.py

# django2\apps\business\__init__.py
default_app_config = "apps.business.apps.BusinessConfig"

apps.py

# django2\apps\business\apps.py
from django.apps import AppConfig

class BusinessConfig(AppConfig):
    name = 'apps.business'
    verbose_name = "客户例子"

效果：
