class UserAdmin(admin.ModelAdmin) 覆盖删除功能，实现多重删除

Question

我正在使用 django 身份验证系统的默认 User 类。

我已经重写了 UserAdmin 类上的 delete_model 函数，如下所示，以便在删除我的用户时执行一些操作。当我转到管理页面上的用户时，它工作正常，然后单击删除按钮。我的问题是当我在 UserAdmin 页面上选择一个或多个用户时，看起来这不是被调用的 delete_model 函数。我该怎么做才能解决它？

from django.contrib import admin

#create a custom model admin which allow to search on the email field
class UserAdmin(admin.ModelAdmin):

    #override the delete method to unset the send email to the deleted_user
    def delete_model(UserAdmin, request, obj):

        #### do something ####

        obj.delete()

#unregister the basic User, and register the new User ModelAdmin
admin.site.unregister(User)
admin.site.register(User, UserAdmin)

Answer 1

这将是 iklinac 描述的解决方案 1：

from django.contrib.auth.admin import UserAdmin as DjangoUserAdmin
from django.contrib.admin.actions import delete_selected as django_delete_selected


class UserAdmin(DjangoUserAdmin):
    actions = ['delete_selected']

    def delete_model(modeladmin, request, obj):
        # do something with the user instance

        obj.delete()

    def delete_selected(modeladmin, request, queryset):
        # do something with the users in the queryset

        return django_delete_selected(modeladmin, request, queryset)
    delete_selected.short_description = django_delete_selected.short_description

admin.site.unregister(User)
admin.site.register(User, UserAdmin)

Answer 2

删除选择是由名为 delete_selected

的 Django 函数完成的

from django.contrib.admin.actions import delete_selected

有两种方法可以解决这个问题

1. 禁用原始 delete_selected 并创建您自己的，您将添加到管理操作中

2. 覆盖 UserModels queryset/manager delete() 方法
