Rails Omniauth Facebook登录重定向注册 [英] Rails Omniauth Facebook login redirects to sign up

问题描述

由于某种原因，我的Omniauth Facebook登录正在重定向到/ users / sign_up＃ = ，但是出现其他情况。我在routes.rb中有这个：

  devise_for：users，：controllers => {：omniauth_callbacks => users / omniauth_callbacks} 
  

我在application.html.erb中有这个：

 <％= link_to，user_omniauth_authorize_path（：facebook，：origin =>root_url）％> 
<％= link_to（image_tag（FB-Login.png），
 user_omniauth_authorize_path（：facebook），：origin =>root_url，class：mycss）％> 
  

我在application_controller.rb中有这个：

  def after_sign_in_path_for（resource_or_scope）
 Rails.logger.level = 0 
 logger.debugafter_sign_in_path_for
 logger.debug会话：＃{@ session.inspect}
 logger.debugomniauth.origin：＃{omniauth.origin}
 logger.debugroot_url：＃{root_url}
 ## if request.env [ 'omniauth.origin'] 
 ## request.env ['omniauth.origin'] 
 request.env ['omniauth.origin'] || root_url 
 end 
  

有趣的是日志语句没有显示在heroku日志中 - 像after_sign_in_path_for一样不叫??

任何帮助赞赏，

解决方案

可能该用户已经存在？

尝试在持久性之前检查用户存在：

  def facebook 
 @user = User.from_omniauth（request.env [omniauth.auth]）
如果@user 
 sign_in_and_redirect @user， event => ：认证＃如果@user没有被激活，这将抛出
 set_flash_message（：notice，：success，：kind =>Facebook）if is_navigational_format？ 
 else 
 session [devise.facebook_data] = request.env [omniauth.auth] 
 redirect_to new_user_registration_url 
 end 
 end 
  




for some reason my Omniauth Facebook login is redirecting to /users/sign_up#= - but otherwise appears to be working. I have this in routes.rb:

devise_for :users, :controllers => { :omniauth_callbacks => "users/omniauth_callbacks" }

I have this in application.html.erb:

 <%= link_to "", user_omniauth_authorize_path(:facebook, :origin=>"root_url") %> 
                      <%= link_to(image_tag("FB-Login.png"),    
 user_omniauth_authorize_path(:facebook), :origin=>"root_url", class:"mycss") %>

I have this in application_controller.rb:

def after_sign_in_path_for(resource_or_scope)
      Rails.logger.level = 0 
      logger.debug "after_sign_in_path_for"
          logger.debug "Session: #{@session.inspect}"
      logger.debug "omniauth.origin: #{omniauth.origin}"
          logger.debug "root_url: #{root_url}"
    ##  if request.env['omniauth.origin']
##    request.env['omniauth.origin']
      request.env['omniauth.origin'] || root_url
  end

Funny thing is the log statements are not showing in the heroku logs - looks like after_sign_in_path_for is not called ??

Any help appreciated, Slavko

解决方案

Maybe that user already exist?

Try to check user existence prior to persistence:

def facebook
  @user = User.from_omniauth(request.env["omniauth.auth"])
  if @user
    sign_in_and_redirect @user, :event => :authentication #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"]
    redirect_to new_user_registration_url
  end
end
