django-allauth社交帐户在登录时连接到现有帐户 [英] django-allauth social account connect to existing account on login

问题描述

我有一个自定义用户模型，我正在使用django-allauth进行社交注册和登录。
当用户使用已经使用电子邮件注册的社交帐户登录时，我试图将现有用户连接到新的社交帐户。我发现了这个链接。

  def pre_social_login（self，request，sociallogin）：
 user = sociallogin.account.user 
 if user.id：
返回
尝试：
 customer = Customer.objects.get（email = user.email）
除了Customer.DoesNotExist：
传递
其他：
 perform_login （请求，客户，无）
  

但是尝试登录时出现错误通过社交帐户。

  RelatedObjectDoesNotExist at / accounts / facebook / login / callback / 
 SocialAccount没有用户。 
  

任何帮助将不胜感激。

我也知道其中的安全性问题。但是我还是想尝试一下。

解决方案

我设法通过稍微修改适配器的代码来使它工作。 / p>

adapter.py

 来自allauth.socialaccount.adapter import DefaultSocialAccountAdapter 
 
类MySocialAccountAdapter（DefaultSocialAccountAdapter）：
 def pre_social_login（self，request，sociallogin）：
 user = sociallogin.user 
 if user.id：
 return 
尝试：
 customer = Customer.objects.get（email = user.email）＃如果用户存在，则将该帐户连接到现有帐户并登录
 sociallogin.state ['process'] ='connect'
 perform_login（request，customer，'none'）
除了Customer.DoesNotExist：
 pass 
  

如果子类化 DefaultSocialAccountAdapter ，我们必须指定 SOCIALACCOUNT_ADAPTER = settings.py 文件


中的 myapp.my_adapter.MySocialAccountAdapter

I have a custom user model and I am using django-allauth for social registration and login. I am trying to connect existing user to new social account when a user login using a social account who already has registered using email. I found this link.

def pre_social_login(self, request, sociallogin):
    user = sociallogin.account.user
    if user.id:
        return
    try:
        customer = Customer.objects.get(email=user.email)
    except Customer.DoesNotExist:
        pass
    else:
        perform_login(request, customer, 'none')

But I'm getting an error when I try to login through social account.

RelatedObjectDoesNotExist at /accounts/facebook/login/callback/
SocialAccount has no user.

Any help will be appreciated.

Also I am aware of the security issue in this. But I still want to try this.

解决方案

I managed to get this working by changing the code for adapter a little bit.

adapter.py

from allauth.socialaccount.adapter import DefaultSocialAccountAdapter

class MySocialAccountAdapter(DefaultSocialAccountAdapter):
    def pre_social_login(self, request, sociallogin): 
        user = sociallogin.user
        if user.id:  
            return          
        try:
            customer = Customer.objects.get(email=user.email)  # if user exists, connect the account to the existing account and login
            sociallogin.state['process'] = 'connect'                
            perform_login(request, customer, 'none')
        except Customer.DoesNotExist:
            pass

If subclassing DefaultSocialAccountAdapter, we have to specify SOCIALACCOUNT_ADAPTER = 'myapp.my_adapter.MySocialAccountAdapter' in settings.py file
