Гем activerecord-jsonb-association не работает с belongs_to?

class CreateTickets < ActiveRecord::Migration[5.1]
  def change
    create_table :tickets do |t|    
      t.jsonb :settings
      t.string :name       
      t.timestamps         
    end
  end
end

class Ticket < ApplicationRecord
  belongs_to :location, store: :settings, optional: true
end

Ticket.create! name: "test", settings: {location_id: 1}
