I'm not sure exactly what you are trying to do, but with Rails 4, but most
of it is unnecessary and is handled automatically unless there's a twist
I'm not seeing here. serialization is now automatic as is responding with
an error if the item isn't found. Unless there's a unique aspect to what
you're doing, you don't need your own serializer. All you should need is
the following:
class ItemsController < ApplicationController
respond_to :json
def index
@items = Item.all
respond_with(@items)
end
def show
@item = Item.find(params[:id])
respond_with(@item)
end
end
