如果用户已经登录，则需要在主页上重定向

Question

我使用omniauth用devise 。 我的控制器在下面

 class OmniauthCallbacksController < Devise::OmniauthCallbacksController
      def facebook
        # You need to implement the method below in your model (e.g. app/models/user.rb)
        @user = User.from_omniauth(request.env["omniauth.auth"])



        if @user.persisted?
          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
    end

如果用户已经登录并坚持下去，这会将用户重定向到注册页面。我要进行哪些更改以将用户重定向到首页......... ?????? 请帮帮我

Answer 1

登录后路径设置了吗？

#application_controller.rb
def after_sign_in_path_for(resource_or_scope)
  case resource_or_scope
  when :user, User

    root_path
  else
    super
  end
end
