Answer 1

你注册了你的班级吗？您可以为此使用 admin.register(User) 装饰器。
代码：

 @admin.register(User)
 class Useradmin(admin.ModelAdmin, DuplicateMixin, MasterDataBaseAdmin):


    search_fields = ["user_name","Gender"]
    ordering = ["user_name"]
    list_filter = [
        "users_name",
        ("Gender",MultiSelectDropdownFilter), ]
    
    list_display = [
        "user_name",
        "Gender",]
