Rails 3 w / Devise：如何根据用户的身份验证来设置两个独立的主页面？ [英] Rails 3 w/ Devise: How to set two separate homepages based on whether the user is authenticated or not?

问题描述

我正在使用Rails 3和Devise创建一个用户到达网站的应用程序，并显示一个包含登录名和注册表单的主页。这个页面有自己的控制器（主页），所以路由是

I am using Rails 3 and Devise to create an app where users arrive to the website and are shown a homepage containing a login and a signup form. This page has its own controller ("homepage") so it's route is

root :to => "homepage#index"

如果用户已经登录，我想显示不同的首页将根据点到

I want to display a different homepage if the users are already logged in. This would account to having the root point to

root :to => "dashboard#index"

有没有办法在routes.rb中有条件路由，允许我检查用户是否被认证，然后将它们路由到这些主页之一？

Is there a way to have a conditional route in routes.rb, that would allow me to check whether the user is authenticated before routing them to one of those homepages?

我尝试使用以下代码，但如果我没有登录，设计要求我登录，所以清楚只有第一个路由可行。

I tried using the following code but if I'm not logged in, devise asks me to log in, so clearly only the first route works.

authenticate :user do
  root :to => "dashboard#index"
end
  root :to => "homepage#index"

此外，我希望url指向www.example.com案例，以便www.example.com/dashboard/index和www.example.com/homepage/index不会出现在浏览器中。

Also, I want the url to point to www.example.com in both cases, so that www.example.com/dashboard/index and www.example.com/homepage/index never appear in the browser.

感谢一百万！

推荐答案

尽管如此，它是专门针对Warden / Devise的。

Try this, it's specific to Warden/Devise though.

root to: "dashboard#index", constraints: lambda { |r| r.env["warden"].authenticate? }
root to: "homepage#index"
