Question

How do I use the ProductDecorator with related objects (products)?

Controller:

def show
    @category = Category.find(params[:id])
end

Product decorator:

decorate :product

def somevalue
   'somevalue'
end

View:

<%= render partial: 'list_item', collection: @category.products %>

Partial:

<%= list_item.somevalue %>

Answer 1

You need to call ProductDecorator.decorate on the Products collection like this:

# View
<%= render partial: 'list_item', collection: ProductDecorator.decorate(@category.products) %>
