如何覆盖用户的管理模型？我认为这会有效，但事实并非如此？
class UserAdmin(admin.ModelAdmin):
list_display = ('email', 'first_name', 'last_name')
list_filter = ('is_staff', 'is_superuser')
admin.site.register(User, UserAdmin)
我不打算覆盖模板，只需更改显示的字段＆amp;排序
解决方案好吗？

您必须先取消注册User：
class UserAdmin(admin.ModelAdmin):
list_display = ('email', 'first_name', 'last_name')
list_filter = ('is_staff', 'is_superuser')
admin.site.unregister(User)
admin.site.register(User, UserAdmin)

以AdminCustom类为例，并使用所需的选项进行自定义，以覆盖默认值。
from django.contrib.auth.admin import UserAdmin
最后，请遵循上述示例
class UserAdminCustom(UserAdmin):
list_display = ('email', 'first_name', 'last_name', 'is_staff', 'is_superuser')
list_filter = ('is_staff', 'is_superuser')
search_fields = ('username', )
答案 2 :(得分：1)
正如@ haifeng-zhang在评论中指出的那样，扩展默认的UserAdmin很有用。
关于此的官方文档可以在这里找到： https://docs.djangoproject.com/en/dev/topics/auth/customizing/#extending-the-existing-user-model
from django.contrib import admin
from django.contrib.auth.admin import UserAdmin as BaseUserAdmin
from django.contrib.auth.models import User
# Define a new User admin
class UserAdmin(BaseUserAdmin):
list_display = ('email', 'first_name', 'last_name')
list_filter = ('is_staff', 'is_superuser')
# Re-register UserAdmin
admin.site.unregister(User)
admin.site.register(User, UserAdmin)
