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.

Decoding the http request TIP: If you ever want to list all the routes of your application you can use rails routes on your terminal and if you want to list routes of a specific resource, you can use rails routes | grep hotel . This will list all the routes of Hotel.
For most applications, you will begin by defining routes in your routes/web.php file. The routes defined in routes/web.php may be accessed by entering the defined route's URL in your browser.
With params . Inside your controller action's you can call params to access form & URL query data. What is params , exactly? It's a method that returns an ActionController::Parameters object, in practice it behaves a lot like a hash.
The Rails controller is the logical center of your application. It coordinates the interaction between the user, the views, and the model. The controller is also a home to a number of important ancillary services. It is responsible for routing external requests to internal actions.
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.

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)
