使用 when 的简单 joi 模式不起作用

Question

我希望打印以下错误：

var joi = require('joi');

var schema = {
  role_type: joi.string(),
  info: {
    address: joi.object({
      postal_code: joi.string(),
      country: joi.string().uppercase().length(2)
    })
      .when('role_type', {
        is: 'org', // When role_type is "org" the address props become required
        then: {
          postal_code: joi.required(),
          country: joi.required()
        }
      })
  }
};

var data = {
  role_type: 'org',
  info: {address: {country: 'AF'}}
};

joi.assert(data, schema);

不幸的是，上面的代码没有产生任何错误。为什么？

在 joi v6 和最新的 v10 上测试。

结果是一个can't reference父对象数据：

References cannot point up the object tree, only to sibling keys, but they can point to their siblings' children

最简单的解决方法是将 .when() 向上移动一层，这样 joi 就会（深度）合并两个 info 子模式

var schema = {
  role_type: joi.string(),
  info: joi.object({
    address: joi.object({
      postal_code: joi.string(),
      country: joi.string().uppercase().length(2)
    })
  })
    .when('role_type', {
      is: 'org',
      then: joi.object({
        address: joi.object({
          postal_code: joi.required(),
          country: joi.required()
        })
      })
    })
};

使用 when 的简单 joi 模式不起作用

Simple joi schema using when does not work

node.js
