When you set up a regular route, you supply a series of symbols that Rails maps to parts of an incoming HTTP request.
match ':controller/:action/:id/:user_id'
Two of these symbols are special: :controller maps to the name of a controller in your application, and :action maps to the name of an action within that controller. Anything other than :controller or :action will be available to the action as part of params.
Mount a Rack-based application to be used within the application.
mount SomeRackApp, :at => "some_route"
Alternatively:
mount(SomeRackApp => "some_route")
All mounted applications come with routing helpers to access them. These are named after the class specified, so for the above example the helper is either some_rack_app_path or some_rack_app_url. To customize this helper‘s name, use the +:as+ option:
mount(SomeRackApp => "some_route", :as => "exciting")
This will generate the exciting_path and exciting_url helpers which can be used to navigate to this mounted app.
