Question

I have a model setup like so:

class Item < ActiveRecord::Base
  belongs_to: media

  def as_json(options={})
    super(:include => :media)
  end
end

class Media < ActiveRecord::Base
  def media_func(some_param)
    ...
    some_val
  end

  def as_json(options={})
    output = super(:include => :media)
    output[:some_attr] = media_func(options[:some_param])
    output
  end
end

I have a controller like this:

class Api::FeedsController < ApplicationController
  def item_list
    @some_param = some_parameter
    @item_list = Item.all
    render :json => @item_list
  end
end

How the heck do I pass @some_param so that the media object receives it when rendering to json?

Answer 1

Just add this to the controller:

render :json => @item_list.as_json(:some_param => @some_param)

Edit. Added the method as_json to the object.
