NAME

Valiant::Validator::Absence - Verify that a value is missing

SYNOPSIS

            

              
              
package Local::Test::Absence;
use Moo;
use Valiant::Validations;
has name => (is=>'ro');
validates name => ( absence => 1 );
my $object = Local::Test::Absence->new();
$object->validate;
warn $object->errors->_dump;
$VAR1 = {
  'name' => [
    'Name must be blank',
  ]
};
            
          

DESCRIPTION

Value must be absent (undefined, an empty string or a string composed only of whitespace). Uses is_present as the translation tag and you can set that to override the message.

SHORTCUT FORM

This validator supports the follow shortcut forms:

            

              
              
validates attribute => ( absence => 1, ... );
            
          

Which is the same as:

            

              
              
validates attribute => (
  absence => +{},
);
            
          

Not a lot of saved typing but it seems to read better.

GLOBAL PARAMETERS

This validator supports all the standard shared parameters: if, unless, message, strict, allow_undef, allow_blank.
