登录后重定向用户，只有在root_path上 [英] Redirect user after log in only if it's on root_path

问题描述

我的Rails应用程序中没有用户保护的 root_path ，即它是一个简单的门户网站主页，具有登录表单。

用户登录后，我希望它进入 dashboard_path 。

我已经这样做了：

  def signed_in_root_path（scope_or_resource）
 dashboard_path 
 end 
  

这显然应该在用户登录时使用，我不想让它去 root_path ，同时仍然保持用户回到上一页，如果它试图击中限制区域，它是超时或未登录。

ie：

restricted_pa​​ge - > login - > restricted_pa​​ge_but_logged_in

我不想改变这种行为，这就是为什么我没有使用 after_sign_in_path ，但是如果要重定向它，如果它在 root_path 或任何不需要用户的路由验证。

我的问题是这不工作。登录后，我被重定向到 root_path ，我相信是因为 after_sign_in_path 之前触发。

有没有办法做到这一点？谢谢！

编辑：这个工作是我第二次登录，即我去 root_path 登录，获取Flash消息，告诉我我已经登录，并在 root_path 上的表单上再次输入用户名和密码。我成功地被重定向到 dashboard_path 。仍然不是我想要的行为。

解决方案

只是一个想法

您可以为签名的url定义两个root url，这将指向仪表板，第二个用于指向登录页面的用户的非签名页面

定义不同的根URL基于一些约束
在routes.rb

登录用户的根URL

 约束（AuthenticatedUser）do 
 root：to => dashboard
 end 
  

未登录用户的根网址

  root：to =>users / signin
  

然后在lib / authenticated_user.rb中创建类AuthenticatedUser

  class AuthenticatedUser 
 def self .matches？（request）
 user_signed_in？ 
 end 
 end 
  

现在如果用户登录root_url将指向仪表板否则它将指向登录页面

您还可以创建两个根（尚未测试）

  root：to => dashboard，：constraints => {user_signed_in？} 
 root：to => users / signin

注意

URL的优先级基于创建顺序，
首先创建 - >最高优先级资源

I have a root_path on my Rails application that is not user-protected i.e. it's a simple portal homepage, with a login form.

After the users log in, I'd like it to go to dashboard_path.

I've done this:

def signed_in_root_path(scope_or_resource)
  dashboard_path
end

This apparently should be used when an user signs in, and I don't want it to go to the root_path, while still keeping the user going back to a previous page if it tries to hit a restricted area and it's either timed out or not logged in.

i.e.:

restricted_page -> login -> restricted_page_but_logged_in

I don't want to change this behavior, and that's why I haven't used after_sign_in_path, but want to redirect it if it's on root_path, or any route that doesn't require user authentication.

My problem is that this is not working. After signing in, I'm getting redirected back to root_path, which I believe is because of after_sign_in_path getting triggered before.

Is there any way to do this? Thanks!

Edit: This works the second time I log in, i.e. I go to root_path, log in, gets the flash message stating me that I'm logged in, and enter username and password again on the form on root_path. I successfully get redirected to dashboard_path. Still, not quite the behavior I want.

解决方案

Just a thought

You can define two root url one for signed in url which will point to dashboard and second for non signed in users which will point to login page

define different root url based on some constraints in routes.rb

root url for signed in users

constraints(AuthenticatedUser) do 
  root :to => "dashboard"
end

root url for non signed in users

root :to=>"users/signin"

then create class AuthenticatedUser in lib/authenticated_user.rb

class AuthenticatedUser
  def self.matches?(request)
    user_signed_in?
  end
end

now if user is signed in root_url will point to dashboard else it will point to signin page

Your can also create two roots using(did not tested it yet)

root :to => "dashboard", :constraints => {user_signed_in?}
root :to => "users/signin"

Note

The priority of url is based upon order of creation, first created -> highest priority resources
