Decorate your instance variables before render
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
