我有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，不知道这是相关的问题，但我想补充一点，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文档似乎建议您可以在任何地方使用会话，并且如果为用户调用登录方法（存储在cookie中的会话的引用可能是？），那么数据将可用，但是当我尝试使在session.user对象数据呼叫，没有数据存在，如果我想要做这样的事情，说你好request.user.first_name，目前还没有这样的可调用的任何数据。Django的1.10：访问会话数据后重定向

superuser.email_address = email_address
superuser.set_password(password)
superuser.first_name = first_name
superuser.last_name = last_name

superuser.save(using=self._db)
return superuser
def create_user(self, email_address, password, first_name, last_name, language):
email_address = self.normalize_email(email_address)
user = AuthLookup()
user.email_address = email_address
user.set_password(password)
user.first_name = first_name
user.last_name = last_name
user.language = language
user.is_staff = False
user.is_superuser = False
user.save(using=self._db)
return user
当我使用此代码，登录后，我得到：

Exception Type: AttributeError at /user/dashboard
Exception Value: type object 'AuthLookup' has no attribute 'objects'
不过，我不叫重定向作为测试，而是做呼叫
if request.user.is_authenticated():
return HttpResponse(request.user.first_name)
在重定向的地方，if语句对True和我得到显示已登录用户的名字页面
在此先感谢您的帮助。
请注明您'UserHandler/backends.py'和'AuthLookup'模型.. –
