I have a table with contacts and would like to make sure that email adresses are not repeated. I can add unique email validation and it works fine:

$rules = $this->validateForm();
$rules['email'] = 'required|unique:interpreters,email,NULL,1’;

The problem is that, when I want to update the record, for example add  mobile number, on save it throws that the email already exists.
That problem is described here:
