NAME¶

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

VERSION¶

version 7.900059

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.

    before foo => sub { ... };

    around foo => sub { ... };

    after foo => sub { ... };
