So, i'm trying to validate if a field is required given a specific scenario. Like this:
cake: Joi.object().keys({
flavor: Joi.string().max(45).required(),
price: Joi.string().length(2).required(),
topping: Joi.string().length(2).required()
})
and in the same schema i have:
authentication: Joi.object().keys({
password: Joi.string().max(45).required(),
login64: Joi.string().max(45).required()
})
and i want to make a validation like:
authentication: Joi.object().keys({
password: Joi.string().max(45).required(),
login64: Joi.string().max(45).when('cake.flavor', {
is: 'chocolate',
then: Joi.required()
} })
i want to make login64 required if the flavor of the cake is chocolate. But nothing seems to work...
A Joy reference is by default relative to the parent of the current value, which in your case is authentication. You need to move a couple of levels up (...) in order to reach cake:
login64: Joi.string().max(45).when('...cake.flavor', {
is: 'chocolate',
then: Joi.required()
})
