Devise根据登录用户角色重定向到特定页面 [英] Devise Redirects to specific page based on User Role on Login

问题描述

我有三个可能的权限，一个用户在我的Rails应用程序，他们是 User.is_admin ， User.is_school 和 User.is_security 。根据我的应用程序的性质，我需要为每个用户做一个单独的主屏幕，这些用户完全不同，我正在工作。我所遇到的问题与Devise在所有用户登录后如何自动重定向到root_path有关，无论我设置了哪些权限。

I have three possible permissions for a User to be in my Rails app, they are User.is_admin, User.is_school, and User.is_security. Based on the nature of my app I need to have a separate home screen for each of these users that do radically different things, which I have working. The problem that I'm having has to do with how Devise auto redirects to root_path after login for all users, regardless of the permissions I have set.

我生成了Devise会话控制器进入用户命名空间，我已经将其覆盖到默认的我的控制器，但现在当我尝试做一个重定向，根据条件许可，我得到一个 DoubleRenderError （显而易见的原因是，在创建会话时，Devise正在重定向到其他地方）。

I generated the Devise Sessions controllers into the Users namespace and I have overwritten it to default to my controller, but now when I try to do a redirect, based on the conditional permissions, I get a DoubleRenderError (The obvious reason being that Devise is redirecting elsewhere when creating the session).

我尝试将其作为after_action运行，甚至尝试覆盖 after_sign_in_path_for 方法，根据Devise文档的方向，但我仍然无法使其工作。任何帮助将不胜感激，谢谢！

I have tried running it as an after_action and even tried overwriting the after_sign_in_path_for method, as per the direction of the Devise docs on the matter, but I still can't get it working. Any help would be appreciated, thank you!

推荐答案

你可以做这样的事情

class ApplicationController < ActionController::Base
  def after_sign_in_path_for(resource)
    if resource.role == 'admin'
      admin_root_path
    else
      user_root_path
    end
  end
end
