当检索到的电子邮件与现有用户的电子邮件匹配时,django allauth facebook重定向到注册？

Question

我成功地能够使用Django(1.6.4)和allauth(0.16.1)以及Python(2.7)通过Google和Facebook登录,预期重定向到settings.LOGIN_REDIRECT_URL,以防没有现有用户从中检索到emailid供应商.但是,当已经存在与从提供者(fb或goolge)检索到的用户具有相同emailid的用户时,它总是重定向到/ accounts/social/signup /#= 注册页面询问:

您即将使用您的Facebook/Google帐户登录example.com.最后一步,请填写以下表格:电子邮件已自动填写.

我曾与测试SOCIALACCOUNT_AUTO_SIGNUP = True或False,但没有效果.我尝试更改facebook的auth_type,但除了"rerequest"之外我没有看到任何其他选项

我有以下settings.py:

ACCOUNT_AUTHENTICATION_METHOD = "email" # Defaults to username_email
ACCOUNT_USERNAME_REQUIRED = False       # Defaults to True
ACCOUNT_EMAIL_REQUIRED = True           # Defaults to False
SOCIALACCOUNT_QUERY_EMAIL = ACCOUNT_EMAIL_REQUIRED
SOCIALACCOUNT_AUTO_SIGNUP = True
SOCIALACCOUNT_EMAIL_REQUIRED = False
ACCOUNT_ADAPTER = "myproject.adapter.MyLoginAccountAdapter"
LOGIN_URL = "/"
LOGIN_REDIRECT_URL = "/users/{id}/mytags"

如何停止此重定向到注册,并将提供程序登录重定向到具有相同emailid的已存在用户的特定LOGIN_REDIRECT_URL？

注意:这个我试过了

• 我已在myproject.adapter.MyLoginAccountAdapter中更新了get_login_redirect_url.仅适用于谷歌,但不适用于Django allauth声称的Facebook - 设置Facebook重定向
• 我尝试过" 使用allauth绕过注册表单 ",但不起作用

更新:

1. 由于这个答案,我意识到通过Facebook的登录将重定向到一个案例中的注册页面:当从Facebook个人资料中检索到的电子邮件与已有用户的emailid匹配时.
2. 我已经更新了这个问题,以便解释上述情况.
3. 总结一下这个问题,这是一个多个提供者帐户具有相同电子邮件ID并且django-allauth不允许互换登录的情况(如果我使用facebook注册一次,则django-allauth将要求我仅使用Facebook而不是谷歌或任何其他提供商与相同的电子邮件ID
4. 我通过使用@receiver(pre_social_login)和raise ImmediateHttpResponse(看看我的答案)解决了有用的链接:这个和这个

谢谢,阿米特

Answer 1

我深入研究了django和django-allauth的谷歌和源代码后解决了这个问题

问题正在解决:我只是希望能够互相登录使用Facebook和谷歌相同的电子邮件ID,并成功登录后始终重定向到LOGIN_REDIRECT_URL,但django-allauth不允许我这样做.相反,它向我提供了一个我不想要的注册页面.

解决方法::使用@receiver(pre_social_login)调用一个函数link_to_local_user(),其登录1,然后使ImmediateHttpResponse这反过来又重定向到LOGIN_REDIRECT_URL
