Rails Routes for Versioned Web Services

I'm new to Rails. Can anyone tell me if the f开发者_运维知识库ollowing is possible, and if you, what would the correct "route" entry be?

I have a controller ItemController with one action (index). When I set it up by default, it's accessible at http://my.app:3000/item, but I want this controller (i.e. this controller only, not the other controllers) to be accessible via http://my.app:3000/api/v1/.

Thanks x

Set it up under a namespace:

namespace :api do
  namespace :v1 do
    resources :items
  end
end

Then you would need to move this controller into app/controllers/api/v1/items_controller.rb and call the class defined in it Api::V1::ItemsController.

Chances are that you're going to h ave some custom logic you want for API actions, so you may want to put that logic in another controller other than ApplicationController. This means this new controller would inherit from Api::V1::BaseController rather than ApplicationController.

On a side note, I cover this kind of thing in the "Designing an API" chapter of my book, Rails 3 in Action.
