Joi Validation- 即使只有一个元素与架构匹配，也验证数组

Question

I would like to validate an array of objects. And joi should validate the whole array even if only one array element matches schema and reject only if all elements don't match the schema for exmaple: schema:

Joi.object({
  data: Joi.array()
    .items(Joi.object({a: Joi.number(), b: Joi.string()})) 
})

This must pass joi validation: [{a:23, b: "Ddd"}, {a:23, b: 34}]

Only one array element validation should be enough to pass the array validation.

This must not pass validation:

[{a:23, b: 23}, {a:23, b: 34}]

Above all elements of the array fails the validation , hence array validation also fails.

Thanks

I am able to solve my problem by using stripUnknown option.

Joi.object({
  data: Joi.array()
    .items(Joi.object({a: Joi.number(), b: Joi.string()}))
    .options({ stripUnknown: { arrays: true } })
})

Above code strips invalid array elements and throws error if no elements passes validation if schema has required.
