Draper gem not decorating associated model

I'm following the Draper gem documentation, but the associated model is not being decorated. Here's a snippet of my top-level decorator:

module Admin
  class OrderDecorator < Draper::Decorator
    delegate_all
    decorates_finders
    decorates_association :line_item

    def amount
      model.amount.nil? ? 0 : model.amount
    end
  end
end

And here's a snippet from my association decorator:

module Admin
  class LineItemDecorator < Draper::Decorator
    delegate_all

    def options
      model.options.present? ? model.options.to_s : 'N/A'
    end
  end
end

Here's the method in the controller that calls the decorator:

  def show
    @subject = Admin::OrderDecorator.find(params[:id])
  end

It's being used in the view like so:

@subject.line_items.each do |li|
  = li.options

...etc...

The options method on LineItemDecorator is just being ignored - if it's nil, it doesn't display anything, rather than 'N/A'. I've put binding.pry in the options method and it never gets called. Can anyone see what I'm missing?

Thanks so much in advance.

I think you need to use plural line_items not singular line_item to make it work because that is how your association is named.

 decorates_association :line_items
