如何确定Rails对象是否为marked_for_destruction？

Question

我有一些碰巧是其他东西的嵌套属性的对象。 当它们被标记为要删除时，Rails会创建一个属性“marked_for_destruction”。 我该如何阅读这个var？

示例Yaml转储：

--- &id001 !ruby/object:LineItem 
attributes: 
  name:Pay
  created_at: 2009-10-12 16:30:51
  updated_at: 2009-10-12 16:30:51
  statement_id: "8"
  amount: "234"
  id: "33"
attributes_cache: {}

errors: !ruby/object:ActiveRecord::Errors 
  base: *id001
  errors: {}

marked_for_destruction: true

Answer 1

Object.marked_for_destruction?
