Question

我有下一个型号：

class User  < ActiveRecord::Base
end

class Customer < User
  has_many :orders, foreign_key: 'customer_id', dependent: :destroy
end

class Translator < User
 has_many :orders, foreign_key: 'translator_id'
end

class Order < ActiveRecord::Base
  belongs_to :customer, class_name: "Customer"
  belongs_to :translator , class_name: "Translator"
end

当我尝试使用翻译和客户加载订单时，我遇到了一个问题：

Order.eager_load(:vox_logs,:customer, :translator)

在这种情况下，客户将被正常加载但翻译不是：

order.translator = nil
order.translator_id = 123

我该如何解决？

编辑：我添加了控制台输出更清晰（它来自订单的功能）：

(byebug) translator
nil
(byebug) translator_id
637
(byebug) Translator.find translator_id
Translator Load (70.1ms)  SELECT  "users".* FROM "users" WHERE       ((users.roles_mask & 4) > 0) AND "users"."id" = $1 LIMIT 1  [["id", 637]]

<Translator id: 637, email: nil, first_name: nil, middle_name: nil,
last_name: nil, native_language: "fr", country: "RU", city: "Липецк"...

STI和预载关系
