将Django社交身份验证与用户注册同步

我创建了一个django项目，该项目具有单独的用户注册表单，并使用 python-social-auth 进行直接登录 . 每当我尝试使用我已经用于通过注册表单创建帐户的电子邮件ID的social_auth登录时，已插入单独的行而不是使用现有的行 .

如果我在将电子邮件ID更改为模型中的唯一身份后尝试通过social_auth登录，则会收到错误“电子邮件ID已存在” . 如果我从电子邮件中删除unique，则单独的条目将出现在User表中，并且它被视为不同的帐户 .

现在问题是，我不需要 separate accounts for same email Id （使用注册表格，Facebook，谷歌创建） . 我需要 synchronize the accounts created using registration form and social auth .
