Make RoR nested in an array
Using the presented gem , I am looking to nest an object in an array, with that array only having one object. I cannot figure out how to do this. Any ideas? The reason for this has to do with how the Google Tag Manager handles advanced ecommerce tracking.
nested 'products' do
property :name, getter: lambda{|*| name }
property :id
end
Spits out:
"products": {
"name" : "Nike Swoosh",
"id" : 8
}
Whenever I want, we exit as:
"products": [ {
"name" : "Nike Swoosh",
"id" : 8
} ]

You can just use the collection in the representable module. Although you only have one object, since you want to wrap it in an array. It technically becomes a collection with one object. Then define a getter with that collection name in the parent. Here's an example:
require 'ostruct'
require 'representable'
require 'representable/json'
class Order < Struct.new(:order, :product)
def products
[product]
end
end
module OrderRepresenter
include Representable::JSON
property :name
collection :products
end
sale = Order.new(name: "An order name", product: {name: "My Product", id: 1})
p sale.extend(SaleRepresenter).to_json
