possible to nest method calls on to_json

I'm trying to do something like this: 

render :json => r.to_json(:methods => [:food_item => {:method => :price_value}])

but it's not working. Is something like this even possible?

thx

edit 1 no association

def food_item
  MenuItem.find(food_id)
end

Is food_item an ActiveRecord association? If so, you could try

render :json => r.to_json(:include => { :food_item => { :only => :price_value } })

I'll refine my answer in response to "edit 1". First, remove your food_item method and add an actual association like this:

belongs_to :food_item, :class_name => "MenuItem", :foreign_key => "food_id"

and then do

render :json => r.to_json(:include => { :food_item => { :only => [:price_value] } })
