Monkey patch to index nested errors for ActiveRecord 4

ActiveRecord Nested Error Indexer

In Rails 5, we have the option index_errors: true to output the nested item index for errors like this:

class Order < ApplicationRecord
  has_many :items, index_errors: true

  accepts_nested_attributes_for :items
end

order = Order.create(items_attributes: [{ price: 1 }, { price: -1 }])
order.errors # #<ActiveModel::Errors... @messages={:*"items[1].price"*: ["must be greater than 0"]}>

BUT IT DOESN'T WORK FOR RAILS 4, so... let's monkey patch it :)
