How to decorate nested attributes (associations) w

Question

My environment:

• Rails 3.2
  • with draper gem

I'm using nested resources and having trouble figuring out where to declare the decorator.

#app/controllers/users_controller.rb
def show
  @user = UserDecorator.find(params[:id])
  @items = @user.items
end

#app/controllers/items_controller.rb
def show
  @item = @user.items.find(params[:id])
end

I tried replacing items with ItemDecorator and it didn't work. Where should I be putting it?

I know that Draper has issues with nested resources in forms, but this isn't a form!

Answer 1

As far as I've understood your problem correctly, you've a model user which has many items, but your items were not decorated?

So add to your UserDecorator:

class UserDecorator < Draper::Base
  decorates :user
  decorates_association :items #, :with => :item 

  [..]
end

class ItemDecorator < Draper::Base
  decorates :item

  [..]
end

Have a look on the source.
