Question

I have an webapplication that uses devise database authentication for all the controllers, however I want to have one controller action where authentication is also done using a token. Can i use devise for this?

Answer 1

Devise strategies have a valid? method that is called to determine if the strategy should be enabled. This allows you to control available auth strategies on a per controller/action basis.

Put this in an initializer:

require 'devise/strategies/base'
require 'devise/strategies/token_authenticatable'
module Devise
  module Strategies
    class TokenAuthenticatable < Authenticatable
      def valid?
        super && params[:controller] == "your controller" && params[:action] == "your action"
      end
    end
  end
end

let me know if it works.
