可否支援 deep_pluck 出 model 裡面序列化的欄位？

e.g
class User < ActiveRecord::Base
  serialize :preferences, Hash
end

# in controller

User.where(id: 1).deep_pluck(preferences: [:food, :car])

以目前 deep_pluck 的設計

users.deep_pluck(preferences: [:food, :car])

預期的輸出格式會是：

[
  {preferences: [{food: xx, car: xx}, {food: xx, car: xx}, ......]}, # user1
  {preferences: [{food: xx, car: xx}, {food: xx, car: xx}, ......]}, # user2
  ...
  ...
]

跟你想要的不太一樣

可能要再想想語法格式的問題
