如何从管理页面中删除此过滤器及其功能?
我正在尝试仅显示其员工状态为true的用户,并且由于过滤器的“按员工状态”设置为页面加载时的“全部”,我认为查询无效。无论如何如何完全删除它?

将list_filter = ()
添加到模型定义中。

是的,我发现另一种更清楚的方法。如果您看到auth类(User Class)的源代码,则admin将如下所示:
class UserAdmin(admin.ModelAdmin):
add_form_template = 'admin/auth/user/add_form.html'
change_user_password_template = None
fieldsets = (
(None, {'fields': ('username', 'password')}),
(_('Personal info'), {'fields': ('first_name', 'last_name', 'email')}),
(_('Permissions'), {'fields': ('is_active', 'is_staff', 'is_superuser',
'groups', 'user_permissions')}),
(_('Important dates'), {'fields': ('last_login', 'date_joined')}),
)
add_fieldsets = (
(None, {
'classes': ('wide',),
'fields': ('username', 'password1', 'password2'),
}),
)
form = UserChangeForm
add_form = UserCreationForm
change_password_form = AdminPasswordChangeForm
list_display = ('username', 'email', 'first_name', 'last_name', 'is_staff')
list_filter = ('is_staff', 'is_superuser', 'is_active', 'groups')
search_fields = ('username', 'first_name', 'last_name', 'email')
ordering = ('username',)
filter_horizontal = ('groups', 'user_permissions',)

if not obj:
return self.add_fieldsets

"""

defaults = {}
if obj is None:
defaults['form'] = self.add_form
defaults.update(kwargs)

def get_urls(self):

def lookup_allowed(self, lookup, value):
# See #20078: we don't want to allow any lookups involving passwords.

在任何应用程序的管理员中,您可以取消注册用户类,定义自定义UserAdmin,然后再次注册:
from django.contrib.auth.models import User
from django.contrib.auth.admin import UserAdmin
...
admin.site.unregister(User)
class UserAdmin(UserAdmin):
model = User
list_filter = ()
admin.site.register(User, UserAdmin)
放置list_filter=()
您将覆盖默认过滤器告诉django您不需要任何过滤器,因此它不会出现。您可以覆盖此Admin Class中默认配置的任何配置。
修改强>: 您必须添加函数queryset,以过滤要显示的对象。为了您的目的,您必须执行以下操作:
admin.site.unregister(User)
class UserAdmin(UserAdmin):
model = User
list_filter = ()
def queryset(self, request):
qs = super(UserAdmin, self).queryset(request)
return qs.filter(is_staff=True)
admin.site.register(User, UserAdmin)
