Validator requiredWhen

[galaczi]

I am trying to validate a form where either emailVisibility or contactFormVisibility should be set to true (or both). So basically I make one of the fields required when the other one is false. This is my code:

emailVisibility: Schema.boolean.optional([
  rules.requiredWhen('contactFormVisibility', '=', false)
]),
contactFormVisibility: Schema.boolean.optional([
  rules.requiredWhen('emailVisibility', '=', false)
]),

Yet the validator allows both values to be false at the same time. The values coming from the form are:

emailVisibility: 'false',
contactFormVisibility: 'false',

If I am not mistaken Adonis converts these to booleans automatically. The rest of the validation happens as expected so the validator is hooked up correctly. What am I missing?

I just realized it's not doing what I want to do, it just checks whether a value is present. But I still don't know how to do what I want. I guess I am looking for a requiredIfNotExists and not send the field with false value to the server? There is no such functionality in the validator at the moment, correct?

Solved it with a custom validator:

validator.rule('requiredWhenFalse', (value: boolean, compiledOptions: string, options) => {
  if(options.root[compiledOptions[0]] === 'false' && !value) {
    options.errorReporter.report(
      options.pointer,
      'requiredWhenFalse',
      'You must choose one',
      options.arrayExpressionPointer
    )
  }

  return
})
