Laravel update model with unique validation rule for attribute

by

Append the id of the instance currently being updated to the validator.

  1. Pass the id of your instance to ignore the unique validator.

  2. In the validator, use a parameter to detect if you are updating or creating the resource.

If updating, force the unique rule to ignore a given id:

//rules
'email' => 'unique:users,email_address,' . $userId,

If creating, proceed as usual:

//rules
'email' => 'unique:users,email_address',
