各网站可以正常登录，但是但是跳转怎么也不能跳回原路径

我做的是自动登录，判断是微信浏览器，自动调用 weixin 的 Omniauth

def check_login
   if is_from_Weixin?
     redirect_to user_omniauth_authorize_path(provider: :weixin)
   else
     authenticate_user!
   end
 end

authenticate_user! 是可以跳转到原路径，是不是我还有什么没有设置

求大神支招

application_controller.rb 的 after_sign_in_path_for：

def after_sign_in_path_for resource
    if resource.is_a?(User) && resource.respond_to?(:blocked?) && resource.blocked?
      sign_out resource
      flash[:alert] = "Your account is blocked. Retry when an admin has unblocked it."
      new_user_session_path
    else
       request.env['omniauth.origin'] || stored_location_for(resource) || root_path
    end
 end

在 app/controller 增加了 omniauth_callbacks_controller.rb

class OmniauthCallbacksController < Devise::OmniauthCallbacksController
  def weixin
    @user = User.find_for_oauth_user(request.env["omniauth.auth"], current_user)
    if @user
      sign_in_and_redirect @user, :event => :authentication
    else
      session["devise.weixin_data"] = request.env["omniauth.auth"]
      redirect_to new_user_registration_url
    end
  end
end
