Using multiple when conditions

[monsieurBoutte]

Context

• node version: 6.11.3
• joi version: 10.0.6
• environment (node, browser): browser
• used with (hapi, standalone, ...): standalone
• any other relevant information: if I comment out one condition at a time, both work on their own.

What are you trying to achieve or the steps to reproduce ?

I've got a radio button group that needs a two part validation schema with both parts conditionally required based off of each other's values. If a user selects the last option 'other', an input field will appear for them to manually enter another number

The first validation should, require there be a selection of the first three if the fourth option is not selected.

The second validation should be, if the selection value is 'other', ignore the input mask and require the input be filled with a 10 digit phone number.

const cardContactSchema = {
  selectedCardNumber: Joi.string()
    .label('Phone Number')
    .when('otherPreferredCardNumber', {
      is: Joi.string().empty(''),
      then: Joi.string().required(),
    }),
  otherPreferredCardNumber: Joi.string()
    .label('Phone Number')
    .when('selectedCardNumber', {
      is: 'other',
      then: Joi.string()
        .replace(/\D/g, '')
        .length(10)
        .required()
        .options({
          language: {
            string: {
              length: 'length must be {{limit}} digits',
            },
          },
        }),
      otherwise: Joi.string().optional(),
    }),
};

Which result you had ?

Error: item added into group otherPreferredCardNumber created a dependencies error(otherPreferredCardNumber)

What did you expect ?

The first validation should, require there be a selection of the first three if the fourth option is not selected.

The second validation should be, if the selection value is 'other', ignore the input mask and require the input be filled with a 10 digit phone number.

Well it's a circular dependency so obviously it won't work, but I don't think you need it to be circular since selectedCardNumber is always required, your 1st when is useless.

[monsieurBoutte]

sorry let me clarify,

The first validation should require there be a selection of the four options available. If and only if the fourth option "other" is selected, should it trigger the second validation on otherPreferredCardNumber

If I remove the first when this schema will require both of them. Theoretically, the otherPreferredCardNumber should be run when the selection is equal to "other" but for some reason, it's running regardless once I remove the first when

Still doesn't make a difference to me, selectedCardNumber will have a value, be it a card number or 'other'.

Inactive, reopen if it's still an issue.

Hi everyone,

I have the same issue when I'm trying to validate dates depending on each others, here my code:

endDate: Joi.date()
    .greater(
      moment()
      .startOf('day')
      .toDate()
    )
    .when('startDate', {
      is: Joi.exist(),
      then: Joi.date().greater(Joi.ref('startDate'))
    })
    .optional(),
startDate: Joi.date()
    .greater(
      moment()
      .startOf('day')
      .toDate()
    )
    .when('endDate', {
      is: Joi.exist(),
      then: Joi.date().less(Joi.ref('endDate'))
    })
    .optional()

error: item added into group startDate created a dependencies error

Do you guys have any ideas to solve this problem?
