beforeField

Similar to the before rule . However, instead of defining a date/offset for comparison, you define a field to check against. For example:

import { schema, rules } from '@ioc:Adonis/Core/Validator'

{
  checkout_date: schema.date(),
  checkin_date: schema.date({}, [
    rules.beforeField('checkout_date')
  ]),
}

Also, you can make use of the beforeOrEqualToField for enforcing the date to be same or after a given field.

{
  published_on: schema.date(),
  drafted_on: schema.date({}, [
    rules.beforeOrEqualToField('published_on')
  ]),
}
