mount

v3.0.9 - Show latest stable - Class: ActionDispatch::Routing::Mapper::Base

mount(app, options = nil)

public

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.
