Devise + Omniauth Facebook重定向到注册 [英] Devise + Omniauth Facebook redirecting to signup

问题描述

我已遵循 https://github.com/plataformatec/这个指南devise / wiki / OmniAuth：-Overview

首先，它验证了我，签了名，并将我保存到db。

First round it authenticated me, signed me in, and saved me to db.

我清除浏览器历史记录并测试了其他用户。

I cleared browser history and tested a different user.

它需要新用户到Facebook页面登录，登录后自动重定向到

It takes new user to facebook page to sign in, and after sign in automatically redirects them to

 http://localhost:3000/users/sign_up#_=_

并且不登录或保存到DB。任何想法？

and does not sign them in or save to DB. Any Ideas?

推荐答案

下面的代码重定向他。原来只是他的Facebook帐号。需要知道他的帐户为什么这样做...

The code below is redirecting him. Turns out it is only his facebook account. Need to know why his account is doing that...

 if @user.persisted?
      sign_in_and_redirect @user #this will throw if @user is not activated
      set_flash_message(:notice, :success, :kind => "Facebook") if is_navigational_format?
 else
      session["devise.facebook_data"] = request.env["omniauth.auth"].except('extra')
      redirect_to new_user_registration_url
 end
