[Question]: Access other model properties in validation function

Is your feature request related to a problem? Please describe. I store my validation rules in separate file. When I’m trying to base validation function on other model property - I’m unable to do it.

Describe the solution you’d like According to doc I was expecting that I should get model as a second parameter. AFAIK I get Vue instance. I’m unable to access other model properties as stated in doc. I’d like use vuelidate as stated in linked doc.

Additional context “@vuelidate/core”: “^2.0.0-alpha.25”, “@vuelidate/validators”: “^2.0.0-alpha.21”, “vue”: “^3.2.6”,

Simplified example rules.ts

const requireIfActive = (value: string, vm: any) => {
  // how to access model property active?
  // vm.active is undefined
  return false
}

export default {
  name: {
    required: requireIfActive
  }
}

TheComponent.vue

<script setup lang="ts">
  import rules from './rules'

  const record = ref({
    active: false,
    name: null,
  })

  useVuelidate(rules, record, { $lazy: true })
}

Is there anything I’m doing wrong?

I am not sure I get what you need here. As for the forEach helper, I can pass the current iterated object to a validator, as as second parameter. Is that something that you feel would help you? For example:

const items = [
  { name: '', surname: '' }, // this entire object gets passed to each rule as a second parameter, pushing the Instance to third.
  { name: '', surname: '' },
]

const sameAsSurname = (value, surroundingState, instance) => value === surroundingState.surname

In order to help you more, I would need to see code 😕

@dobromir-hristov OMG - I’m taking back everything what I’ve just written!

Couple of minutes later and it works like a charm! It looks like I get a problem with npm update or so, because now I get the behavior I was looking for.

Sorry for inconvenience.

Thanks!
