Please read everything in the Rails Guide to Routing. There are two main cases there:

• RESTful routes: only use GET, PUT, POST, DELETE. Rails maps that by using the method resources. resources :pages will lead to the following routes (and URLs) automatically:

      sites GET    /sites(.:format) {:action=>"index", :controller=>"sites"}
            POST   /sites(.:format) {:action=>"create", :controller=>"sites"}
   new_site GET    /sites/new(.:format) {:action=>"new", :controller=>"sites"}
  edit_site GET    /sites/:id/edit(.:format) {:action=>"edit", :controller=>"sites"}
       site GET    /sites/:id(.:format) {:action=>"show", :controller=>"sites"}
            PUT    /sites/:id(.:format) {:action=>"update", :controller=>"sites"}
            DELETE /sites/:id(.:format) {:action=>"destroy", :controller=>"sites"}
  

• Other routes: There is a rich set of methods you can use in your routes file to add additional routes. But keep in mind: If you just want to address a resource, it is better to stick to restful routes. A typical example is_ match ':controller(/:action(/:id))'. This allows URLs like:

  • localhost:3000/sites/help: controller == SitesController, action == help
  • localhost:3000/sites/search/something: controller == SitesController, action == search, parameter in params is something under the key id. So inside the action search, you will find params[:id] bound to "something".
