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.
