在Django中使用python-social-auth和电子邮件注册复制电子邮件

I'm using both python-social-auth and email registration in my project. For the user model I use a subclass of AbstractBaseUser:

我在我的项目中使用python-social-auth和电子邮件注册。对于用户模型,我使用AbstractBaseUser的子类:

class User(AbstractBaseUser):
    USERNAME_FIELD = 'email'


AUTH_USER_MODEL = 'userprofile.User'

But when a user that is registered with his email ([e-mail]) and password tries to login with his Facebook account that is associated with the same email address, I get the following error:

但是,如果用他的电子邮件注册的用户([e-mail])和密码尝试使用与同一电子邮件地址关联的Facebook帐户登录,则会收到以下错误:

IntegrityError at /social/complete/facebook/
duplicate key value violates unique constraint "userprofile_user_email_key"
DETAIL:  Key (email)=([e-mail]) already exists.

When somebody registers with his Facebook account and then logs in everything works fine. The problem appears when he registers with his email (I'm using django-registration), so we have an instance of User (but not UserSocialAuth), and then we tries to login with his Facebook account associated the same email address.

当有人注册他的Facebook帐户,然后登录一切正常。当他注册他的电子邮件时我会出现问题(我正在使用django-registration),因此我们有一个User实例(但不是UserSocialAuth),然后我们尝试使用与他相同的电子邮件地址关联的Facebook帐户登录。

Problem solved. The issue was about the order in pipeline that has to be the following:

问题解决了。问题在于管道中的顺序必须如下:

DEFAULT_AUTH_PIPELINE = (
    'social.pipeline.social_auth.social_details',
    'social.pipeline.social_auth.social_uid',
    'social.pipeline.social_auth.auth_allowed',
    'social.pipeline.social_auth.social_user',
    'social.pipeline.user.get_username',
    'social.pipeline.mail.mail_validation',
    'social.pipeline.social_auth.associate_by_email',
    'social.pipeline.user.create_user',
    'social.pipeline.social_auth.associate_user',
    'social.pipeline.social_auth.load_extra_data',
    'social.pipeline.user.user_details'
)

Many thanks for the author of the library who helped to figure this out.

非常感谢图书馆的作者,他帮助解决了这个问题。
