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)

Answer 3

Have you tried this ?

item = Item.find(params[:id]) 
item <<{ :status => "Success" }

render :json => item.to_json
