Joi validation multiple conditions

rated 0 times [ 190] [ 2] / answers: 1 / hits: 43573 / 10 Years ago, wed, october 22, 2014, 12:00:00

I have the following schema:

var testSchema = Joi.object().keys({

    a: Joi.string(), 

    b: Joi.string(), 

    c: Joi.string().when('a', {'is': 'avalue', then: Joi.string().required()})

});

but I would like to add a condition on c field definition so that it is required when:

a == 'avalue' AND b=='bvalue'

How can I do that?

You can concatenate two when rules:

var schema = {

    a: Joi.string(),

    b: Joi.string(),

    c: Joi.string().when('a', { is: 'avalue', then: Joi.string().required() }).concat(Joi.string().when('b', { is: 'bvalue', then: Joi.string().required() }))

};
