在Rails 3中为OmniAuth创建命名路由 [英] Create named routes for OmniAuth in Rails 3

问题描述

观看了Ryan出色的Railcast 简单的OmniAuth 之后，我设法实现了身份验证在我的应用中.

After having watched Ryan's excellent Railcast Simple OmniAuth, I've managed to implement authentication in my app.

一切正常，但是在我看来，我的链接看起来像这样:

Everything is working fine, but in my view I have links that look like this:

<%= link_to 'Sign in with Twitter', '/signin/twitter' %>
<%= link_to 'Sign in with Facebook', '/signin/facebook' %>

我想知道是否有一种优雅的方法来创建命名路由以替换为:

I was wondering if there is an elegant way to create a named route to replace that with:

<%= link_to 'Sign in with Twitter', signin_twitter_path %>
<%= link_to 'Sign in with Facebook', signin_facebook_path %>

或:

<%= link_to 'Sign in with Twitter', signin_path(:twitter) %>
<%= link_to 'Sign in with Facebook', signin_path(:facebook) %>

OmniAuth已经处理了这些路由...在我的routes.rb文件中，我只有用于回调和退出的内容:

OmniAuth already handles those routes... In my routes.rb file I only have stuff for callbacks and signing out:

match '/signin/:provider/callback' => 'sessions#create'
match '/signout' => 'sessions#destroy', :as => :signout

所以我不知道在哪里可以创建那些命名的路由.

So I don't know where I could create those named routes.

任何帮助将不胜感激.谢谢.

Any help will be appreciated. Thanks.

推荐答案

请注意，在link_to中，您只是为route参数提供了一个字符串.因此，您只需在助手文件中定义一个方法即可.

Notice that in link_to, you're just providing a string for the route argument. So you can just define a method in a helpers file.

# application_helper.rb
module ApplicationHelper
  def signin_path(provider)
    "/auth/#{provider.to_s}"
  end
end

# view file
<%= link_to 'Sign in with Twitter', signin_path(:twitter) %>

如果您想获取所有元数据

If you want to get all meta

# application_helper.rb
module ApplicationHelper
  def method_missing(name, *args, &block)
    if /^signin_with_(\S*)$/.match(name.to_s)
      "/auth/#{$1}"
    else
     super
    end
  end
end

#view file
<%= link_to 'Sign in with Twitter', signin_with_twitter %>
