NAME

Validation::Class::Simple - Simple Ad-Hoc Data Validation

CONTENTS

VERSION

version 7.900056

SYNOPSIS



    use Validation::Class::Simple;

    my $params = {
        name  => Root,
        email => root@localhost,
        pass  => s3cret,
        pass2 => s2cret
    };

    # define object specific rules
    my $rules = Validation::Class::Simple->new(
        # define fields on-the-fly
        fields => {
            name  => { required => 1 },
            email => { required => 1 },
            pass  => { required => 1 },
            pass2 => { required => 1, matches => pass },
        }
    );

    # set parameters to be validated
    $rules->params->add($params);

    # validate
    unless ($rules->validate) {
        # handle the failures
        warn $rules->errors_to_string;
    }



DESCRIPTION

Validation::Class::Simple is a simple validation module built around the powerful Validation::Class data validation framework.

This module is merely a blank canvas, a clean validation class derived from Validation::Class which has not been pre-configured (e.g. configured via keywords, etc).

It can be useful in an environment where you wouldn’t care to create a validation class and instead would simply like to pass rules to a validation engine in an ad-hoc fashion.

QUICKSTART

If you are looking for a data validation module with an even lower learning curve built using the same tenets and principles as Validation::Class which is as simple and even lazier than this module, please review the documentation for Validation::Class::Simple::Streamer. Please review the GUIDED-TOUR in Validation::Class::Cookbook for a detailed step-by-step look into how Validation::Class works.

RATIONALE

If you are new to Validation::Class, or would like more information on the underpinnings of this library and how it views and approaches data validation, please review Validation::Class::Whitepaper.

PROXY METHODS

Each instance of Validation::Class::Simple is associated with a prototype class which provides the data validation engine and keeps the class namespace free from pollution and collisions, please see Validation::Class::Prototype for more information on specific methods and attributes.

Validation::Class::Simple is injected with a few proxy methods which are basically aliases to the corresponding prototype (engine) class methods, however it is possible to access the prototype directly using the proto/prototype methods.
