Other Configurations

Custom Access Token Generator

By default a 128 bit access token will be generated. If you require a custom token, such as JWT, specify an object that responds to .generate(options = {}) and returns a string to be used as the token.

Doorkeeper.configure do
  access_token_generator "Doorkeeper::JWT"
end

JWT token support is available with Doorkeeper-JWT.

Custom controllers

By default Doorkeeper's main controller Doorkeeper::ApplicationController inherits from ActionController::Base. You may want to use your own controller to inherit from, to keep Doorkeeper controllers in the same context than the rest your app:

Doorkeeper.configure do
  base_controller 'ApplicationController'
end

Also you could override Doorkeeper::ApplicationMetalController that is ActionController::API by default.

Doorkeeper.configure do
  base_metal_controller 'ApplicationController'
end

Customizing errors

If you don't want to use default Doorkeeper error responses you can raise and rescue it's exceptions. All you need is to set configuration option handle_auth_errors to :raise. In this case Doorkeeper will raise Doorkeeper::Errors::TokenForbidden, Doorkeeper::Errors::TokenExpired, Doorkeeper::Errors::TokenRevoked or other exceptions that you need to care about.
