问题描述
我正在为库存创建签入/签出应用程序.用户不需要密码或电子邮件，只需要输入数字或扫描带有条形码的卡即可.因此，我使用的是自己的名为 Members 的成员，而不是使用auth/users模型.Eveything工作正常，我可以登录/注销，但是当我尝试签出项目时问题就开始了.然后，我得到一个错误 Member对象没有属性'session'
I am creating a checkin/checkout application for inventory. The users do not need a password or email and only need to enter a number or scan a card with their barcode. So instead of using the auth / users model, I am using my own called Members. Eveything works fine, I can login / logout but the issue starts when I try to checkout an item. I then get an error Member object has no attribute 'session'
如何解决此错误?

推荐答案
如评论中所述，问题在于 check_in_out_item 期望 Request ，因为您已经装饰它，但是您要传递它 user ，它是一个 Member .您需要修改 check_in_out_item 以接受 Request 而不是 Member ，或删除装饰器.
As stated in the comments, the problem is that check_in_out_item is expecting a Request since you've decorated it, but you are passing it user, which is a Member. You need to modify check_in_out_item to accept a Request instead of a Member or remove the decorator.
