NAME

DBIx::Class::Validation - Validate all data before submitting to your database.

SYNOPSIS

In your base "DBIx::Class" package:

__PACKAGE__->load_components(qw/... Validation/);

And in your subclasses:

__PACKAGE__->validation(
  module => 'FormValidator::Simple',
  profile => { ... },
  filters => 0,
  auto => 1,
);

And then somewhere else:

eval{ $obj->validate() };
if( my $results = $EVAL_ERROR ){
  ...
}

METHODS

validation

__PACKAGE__->validation(
  module => 'FormValidator::Simple',
  profile => { ... },
  filters => 0,
  auto => 1,
);

Calls "validation_module", "validation_profile" and "validation_auto" if the corresponding argument is defined.

validation_module

__PACKAGE__->validation_module('Data::FormValidator');

Sets the validation module to use. Any module that supports a check() method just like "Data::FormValidator"'s can be used here, such as "FormValidator::Simple".

Defaults to FormValidator::Simple.

validation_profile

__PACKAGE__->validation_profile(
  { ... }
);

Sets the profile that will be passed to the validation module.

validation_auto

__PACKAGE__->validation_auto( 1 );

Turns on and off auto-validation. This feature makes all UPDATEs and INSERTs call the "validate" method before doing anything.

The default is for validation_auto is to be on.

validation_filter

__PACKAGE__->validation_filter( 1 );

Turns on and off validation filters. When on, this feature will make all UPDATEs and INSERTs modify your data to that of the values returned by your validation modules check method. This is primarily meant for use with "Data::FormValidator" but may be used with any validation module that returns a results object that supports a valid() method just like "Data::FormValidator::Results".

Filters modify your data, so use them carefully.

The default is for validation_filter is to be off.

validate

$obj->validate();

Validates all the data in the object against the pre-defined validation module and profile. If there is a problem then a hard error will be thrown. If you put the validation in an eval you can capture whatever the module's check() method returned.

EXTENDED METHODS

The following "DBIx::Class::Row" methods are extended by this module:-

insert
update
