我有一个django的自定义用户类，因为我需要使用电子邮件地址而不是用户名，不确定这是否与问题相关，但我想添加以防万一。我试图在成功登录后将用户重定向到他们的仪表板，但是，当我尝试通过URL调用重定向时，我似乎失去了通过request.user访问登录用户数据的能力。如何将页面从登录重定向到仪表板，并在两个视图之间维护用户的会话数据？会话和身份验证系统的django文档似乎建议你可以在任何地方使用会话，如果为用户调用登录方法，数据将可用（对cookie中存储的会话的引用可能？）但是当我尝试时要调用session.user对象中的数据，那里没有数据，如果我想做类似的事情，比如hi request.user.first_name，那么目前没有任何数据可供调用。

当我使用此代码时，登录后我得到：

21. user = AuthLookup.objects.get(pk=user_id)
Exception Type: AttributeError at /user/dashboard
Exception Value: type object 'AuthLookup' has no attribute 'objects'
但是，我不会将重定向称为测试，而是进行调用
if request.user.is_authenticated():
return HttpResponse(request.user.first_name)
在重定向的位置，if语句评估True，我得到一个显示登录用户的名字的页面
提前感谢您的帮助。

我真的不知道这个问题与会话有什么关系。
您收到该错误是因为您的AuthLookup模型中有拼写错误;您定义object而不是objects。
