Decorate Devise current_user with Draper

Draper is awesome.

I normally use the handy decorates_assigned method to decorate model objects in controllers.

Devise makes the currently signed in user available through a current_user (or current_admin, etc.) method. To decorate this with your Draper UserDecorator, just add the following method to ApplicationController:


def current_user

This just calls decorate on the model object returned by the Devise helper. The &. is Ruby 2.3’s safe navigation method and ensures that the call to decorate doesn’t raise an exception if no user is signed in (current_user is nil). For older Ruby versions, you can use Rails’ #try method:


h.t. Ariejan de Vroom for the original idea.
