Question

我一直在使用当前项目进行社交身份验证，但是遇到一个错误，根据使用的社交媒体平台登录，还会导致两个错误。

从社交媒体平台成功重定向后，我从“定制模型管理器”创建用户收到错误消息，该用户用户必须输入Google身份验证的密码或用户必须输入Facebook的密码验证。

从以上这些错误中可以总结出，Django正在尝试从社交平台重定向后立即创建用户帐户。

我的第一个问题是，这种行为是否应视为正常现象，因为如果用户已经拥有一个帐户，可能会有些麻烦。

第二，如果行为正常，那么我应该如何完成注册过程。

自定义用户模型

def create_user(self, email,username, password=None, is_active=True, is_admin= False, is_staff = False, is_profiled =False):
        if not email:
            raise ValueError("User must enter an email address.")
        if not password:
            raise ValueError("User must enter a password.")
        if not username:
            raise ValueError("User must enter a username.")
        user_obj = self.model(email= self.normalize_email(email),
        username = username )
        user_obj.set_password(password)
        user_obj.staff = is_staff
        user_obj.admin = is_admin
        user_obj.active = is_active
        user_obj.profiled = is_profiled
        user_obj.username = username
        user_obj.save(using= self._db)

        return user_obj

谢谢

Answer 1

是的，pytjon-social-auth如果未检测到用户是否已经在您的网站上创建帐户，则会自动创建该用户。

引发的错误是因为你正迫使这些值支票上的自定义create_user方法。如果您的正常功能需要这些值，则可以选择以下几种方法：

查看是否可以添加任何范围以从auth提供程序中检索它们，通常在其后提供电子邮件。
使用partial pipeline功能向用户显示可以填写必填字段的表单。

如果这些字段不强制你的应用程序，然后尝试删除该约束。

Answer 2

在电子邮件之后添加自己的请求

def create_user(self, email,username, password=None, is_active=True, is_admin= False, is_staff = False, is_profiled =False):
