       if authentication
          sign_in authentication.user
          redirect_to root_url
       else
         if(User.where(:email => auth['extra']['raw_info']['email']).exists?)
            flash[:notice] = "You already have account in ibetter"

电子邮件ID不是从twitter获取的.请帮忙

Answer 1

Twitter没有通过API向您发送电子邮件.

如果你使用omniauth-facebook gem,这可以工作,但是twitter没有为你提供电子邮件 - 你必须创建一个解决方法.

例如,在第二步中要求用户填写他/她的电子邮件地址.

Answer 2

接受的答案已过时.Twitter现在通过此特别许可表格提供电子邮件.填写请求特殊权限的表单并等待批准.
