=head1 NAME
Validation::Class::Moose - Marries Validation::Class and Moose through Traits
=head1 VERSION
version 5.85
=head1 DESCRIPTION
Validation::Class::Moose is a L<Moose> role that infuses the power and flexibility
of L<Validation::Class> into your Moose classes. Validation::Class::Moose, by design,
is not designed for attribute type checking, the Moose type constraint system exists
for that purpose and works well, ... instead, its purpose is suited for validating
attribute values (parameters).
This class is experimental and hasn't been used in production. While it has been
tested, please note, the API may change.
=head2 SYNOPSIS
package Identify;
use Moose;
with 'Validation::Class::Moose';
has login => (
is => 'rw',
isa => 'Str',
traits => ['Rules'],
rules => {
label => 'User Login',
error => 'Login invalid.',
required => 1,
validation => sub {
my ( $self, $this_field, $all_params ) = @_;
return $this_field->{value} eq 'admin' ? 1 : 0;
}
}
);
has password => (
is => 'rw',
isa => 'Str',
traits => ['Rules'],
rules => {
label => 'User Password',
error => 'Password invalid.',
required => 1,
validation => sub {
my ( $self, $this_field, $all_params ) = @_;
return $this_field->{value} eq 'pass' ? 1 : 0;
}
}
);
package main;
my $id = Identify->new(login => 'admin', password => 'xxxx');
my $rules = $id->rules;
unless ( $rules->validate ) {
exit print $rules->errors_to_string;
}
