Decorate your instance variables before render

gem 'defer_draper'

Add before_filter :decorate_all in controllers you want to decorate.It accepts regular filter options, as :only, :except, etc

before_filter :decorate_all, only: [:index, :show]

All instance variables (starting with @) that have a decorator will be decorated before they are avaiable in the view.

• Add a option to select what variables to decorate
  • decorate_all exclude: [:foo, :bar] # decorates all except @foo and @bar
  • decorate_all include: [:foo] # decorates only @foo
• RSpec
