Tips for establishing conditional guidelines and mandatory fields within Vue?

Struggling to implement conditional required fields on a form. The approach I've taken is by setting a data field notRequired: false, and then using it in the fields like this: :required="!notRequired". This allows me to make certain fields not required based on specific conditions. However, despite this setup, error messages still appear due to the rules set for each field. Is there a way to also make these rules conditional?

<template>
 <v-text-field
  label='Agency Name'
  v-model='agency.name'
  :rules='nameRules'
  :required="!notRequired"
  required>
 </v-text-field>
 <v-text-field
  label='Agency Code'
  :rules='codeRules'
  :required="!notRequired"
  v-model='agency.code'>
 </v-text-field>
 <v-text-field
  label='Agency location'
  :rules='locationRules'
  :required="notRequired"
  v-model='agency.location'>
 </v-text-field>
</template>

<script>
 export default {
  data: function () {
    return {
      notRequired: false,
      agency: {
        name: '',
        code: '',
        location: '',
      }
      nameRules: [
        value => !!value || 'Please enter name'
      ],
      codeRules: [
        value => !!value || 'Please enter code'
      ],
      locationRules: [
        value => !!value || 'Please enter location'
      ],
    }
  }
 }
</script>

Answer №1

If ternary operator is utilized, additional rules can be included conditionally based on the value of notRequired:

 <v-text-field
   label="Agency Name"
   v-model="agency.name"
   :rules="notRequired ? 'nameRules' : []" <!-- This section controls the rule set -->
   :required="!notRequired">
 </v-text-field>
