我想建立一个类似的，但显著简单的用户列表页面查询过滤器菜单：Django的查询过滤器菜单
用户可以申请单独的过滤器，或者把它们。我更喜欢AJAX，但很高兴开始使用“应用过滤器”提交按钮。
class User(AbstractBaseUser):
id = models.AutoField(primary_key=True)

过滤器： - 可 - BooleanField，如果可在指定日期的 - 位置 - CharField的选择，可以选择1点 - 贸易 - BooleanField的选择，可以选择多个 - 会员 - 是选定工会的成员
当前有通用的ListView和UserManager（）充满最近键入和未经测试的查询，可能需要很多工作。

谢谢应用滤镜
