Question

Say i have this short code:

but i needed to insert/push extra information to the returned json object, how do i do that?

Lets say i need to insert this extra info:

message : "it works" 

Thanks.

Answer 1

item = Item.find(params[:id]) item["message"] = "it works" render :json => item.to_json 

Answer 2

The to_json method takes an option object as parameter . So what you can do is make a method in your item class called as message and have it return the text that you want as its value .

class Item  < ActiveRecord::Base  def message   "it works"  end end  render :json => item.to_json(:methods => :message)
