版本化 Web 服务的 Rails 路由

Question

I'm new to Rails. Can anyone tell me if the following 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 (ie this controller only, not the other controllers) to be accessible via http://my.app:3000/api/v1/ .

Thanks x

Vanessa

Answer 1

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 .
