Question

我一直在敲打这个问题。在同时保存新引荐（父对象）和约会（子）时会出现问题。我已经完成了与其他嵌套对象类似但似乎无法使其与单表继承 - 约会表一起使用。出于某种原因，inverse_of不会将新引荐的id传递给约会。

class Referral < ActiveRecord::Base

  has_many :appointments, class_name: 'Appointment::Base', inverse_of: :referral

  accepts_nested_attributes_for :appointments

end

class Appointment::Base < ActiveRecord::Base

  self.table_name = 'appointments'

  belongs_to :referral, inverse_of: :appointments

end

视图中的

fields_for :appointments do |a|

感谢任何帮助。

Answer 1

在class_name子句中使用referral belongs_to怎么样？像这样：

class Appointment::Base < ActiveRecord::Base
  ...
  belongs_to :referral, class_name: 'Referral', inverse_of: :appointments
end

对于Base

，Rails可能与Appointment（Referral）在同一名称空间中查找

Rails嵌套属性/ inverse_of和STI
