Ruby on Rails : get route using controller, action

问题:

I am quite new to RoR and I am looking for a way of getting a route for a given controller, action & param.

Something similar to url_for() but without the domain and protocol.

Lets say I have :

params = {"controller"=>"controller", "action"=>"edit", "project_id"=>"1"}

I need to get :

route = "/controller/edit/1"

It would be best if I do not have to manually build the route and if I don't need to split the result of url_for().

Does RoR natively support such a feature? It's probably an easy question, but I couldn't find an answer.

回答1:

This is the helper that will generate a path like you want:

edit_controller_path(project_id: 1)

You can use this Helper to generate the full path (including host) of the link:

edit_controller_url(project_id: 1)

Edit : More info available at http://guides.rubyonrails.org/routing.html#path-and-url-helpers

You should be able to use the following

link_to "Link Content", :controller => "my_controller", :action => "my_action", :project_id => 1

This will produce an <a> with a link to your controller/action.
