How to build a JSON response made up of multiple models in Rails

Question

First, the desired result

I have User and Item models. I\'d like to build a JSON response that looks like this:

{
  \"use         


        

Answer 1

Incase anyone is looking for an alternative solution for this, this is how I solved this in Rails 4.2:

def observe
  @item = some_item
  @user = some_user

  respond_to do |format|
    format.js do
      serialized_item = ItemSerializer.new(@item).attributes
      serialized_user = UserSerializer.new(@user).attributes
      render :json => {
        :item => serialized_item, 
        :user => serialized_user
      }
    end
  end
end

This returns the serialized version of both objects as JSON, accessible via response.user and response.item.
