选项完成
-我已经删除了admin.py中的所有is_staff属性,但仍然得到一个错误。
-对其进行多次重构,以检查问题是否存在于代码的不同区域 在这一点上,我被卡住了。有人能帮我调试一下吗 当Django“谈论”这个领域时,我会在第一次回顾中检查这个模型 例如,我在模型中找不到任何密码或password1或password2字段
@property
def is_staff(self):
"""
Is the user a member of staff?
"""
return self.is_staff
上面的代码创建了导致错误的递归执行
@property
def is_admin(self):
"""
Is the user a member of staff?
"""
return self.is_staff
你必须添加这一行,它将在django admin中过滤你的数据。我也有同样的问题,我很喜欢在我的admin.py文件中这样做,或者要了解更多的简要信息,你可以查看这个精彩的教程:
