Devise ignore my custom strategy

Question

I want to create a custom auth strategy for accessing the API. I followed the example code at Devise ignoring custom strategy.

The problem is that the valid? method in my Api strategy is never run (based on trying to pry in it).

My code:

module Devise
  module Strategies
    class Api < Devise::Strategies::Base
      def valid?
        binding.pry
        params[:request_source] == 'api'
      end

      def authenticate!
        #do stuff here

        if user
          success!(user)
        else
          warden.custom_failure!
          render :json=> {:success=>false, :message=>"Error with your login or password"}, :status=>401
        end
      end
    end

    Warden::Strategies.add(:api, Devise::Strategies::Api)

  end
end

and in the devise initializer:

config.warden do |manager|
  manager.default_strategies.unshift :api
end

What ever I do, it seems like Devise always use its default strategy. AFAIK, this should be enough...

-------EDIT--------

I require the strategy like this at the very top of my devise initializer:

require Rails.root.join('app/devise/strategies/api')

I know the strategy is loaded at boot time since if I put a pry call inside the class, it will start a pry session. But the Pry calls inside the methods are never run. :-S

Found the answer!

I had to use this:

config.warden do |manager|
  manager.default_strategies(scope: :user).unshift :api
end

to make it work. Weird thing is, a lot of the sample code I saw on the net did not use it :-S
