I've become a big fan of decorators, especially [Draper](https://github.com/jcasimir/draper).
|
||
|
|
|
||
|
|
Decorators allow you to move view related functionality for your models in to separate decorator classes. This keeps both your models and views clean and readable.
|
||
|
|
|
||
|
|
Anyway, if you use Devise you're provided with a `current_user` helper. However, this helper returns an instance of `User` - without your decorators. To enable decorators for your `current_user` by default, simple add this to `app/controllers/application_controller.rb`:
|
||
|
|
|
||
|
|
:::ruby
|
||
|
|
def current_user
|
||
|
|
UserDecorator.decorate(super) unless super.nil?
|
||
|
|
end
|
||
|
|
|
||
|
|
Now, anywhere in your views where you call `current_user` you'll get a decorated version instead.
