Question

I’m creating a JSON API for my application. I’d like to use rocket_pants for the JSON API and doorkeeper to provide OAuth2 support.

My problem is that it seems that once I change my controller to extend rocket pants controller the doorkeeper methods are no longer available.

So, as soon as I’m changing the declaration of the controller to class Api::V1::ApiController < RocketPants::Base, I’m getting this error:

in `<class:ApiController>': undefined method `doorkeeper_for' for Api::V1::ApiController:Class (NoMethodError)

It probably makes sense, since rocket pants has no way of knowing about doorkeeper, but I’d like to know what I should do in order to make it recognize doorkeeper.

Answer 1

If you use doorkeeper 0.4.1 or up, you can add the doorkeeper filter to your controller:

class MetalController < ActionController::Metal
  include AbstractController::Callbacks # you might want to skip this for rocket_pants based controller
  include ActionController::Head
  include Doorkeeper::Helpers::Filter

  doorkeeper_for :all

  def index
    self.response_body = { :ok => true }.to_json
  end
end

Since rocket_pants already includes AbstractController::Callbacks you can skip it, so your controller would look like:

class MetalController < RocketPants::Base
  include ActionController::Head
  include Doorkeeper::Helpers::Filter

  version 1

  doorkeeper_for :all
end
