Mongoid 5 has_many命令

Question

我有以下设置：

class Evaluation
  include Mongoid::Document
  default_scope -> { order("_id ASC") }

  has_many :children, order: "position ASC"
end

class Child
  include Mongoid::Document
  default_scope -> { order("_id ASC") }

  field position, type: Integer, default: 0
end

当我致电evaluation.children时，position订单不受尊重。我该怎么办？

Answer 1

这对我有用：

has_many :children, order: :position.asc
