ruby on rails - Render json and nested attributes -

i have these classes:

class product  attr_accessible :name, ...  has_many :images end  class image  attr_accessible :image, :position, :product_id, :title  belongs_to :product end 

action:

def list   render :json => {:result => "ok", :records => product.all} end 

how can include own images every product nested attribute , not enumerate attributes in product?

you can use to_json(:include => :attr)

def list   render :json => {:result => "ok", :records => product.all}.to_json(:include => :images) end
