如何檢查兩個屬性是否等於 Joi 中另一個對象的屬性？

Question

是否可以讓Joi檢查source.listId === destination.listId && source.index === destination.index然后返回錯誤？

我的例子：

const schema = Joi.object({
  source: Joi.object().keys({
    listId: Joi.string()
      .length(24)
      .required()
      .when('...destination.index', {
        is: Joi.equal(Joi.ref('index')),
        then: Joi.disallow(Joi.ref('...destination.listId'))
      }),
    index: Joi.number()
      .integer()
      .positive()
      .required()
  }),
  destination: Joi.object().keys({
    listId: Joi.string()
      .length(24)
      .required(),
    index: Joi.number()
      .integer()
      .positive()
      .required()
  })
});

解決了

我還必須使用when驗證source.index屬性：

const schema = Joi.object({
  source: Joi.object().keys({
    listId: Joi.string()
      .length(24)
      .required()
      .when('...destination.index', {
        is: Joi.equal(Joi.ref('index')),
        then: Joi.disallow(Joi.ref('...destination.listId'))
      }),
    index: Joi.number()
      .integer()
      .positive()
      .required()
      .when('...destination.listId', {
        is: Joi.equal(Joi.ref('listId')),
        then: Joi.disallow(Joi.ref('...destination.index'))
      })
  }),
  destination: Joi.object().keys({
    listId: Joi.string()
      .length(24)
      .required(),
    index: Joi.number()
      .integer()
      .positive()
      .required()
  })
});
