Adding validation_filter support for FormValidator::Simple.
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 => { ... }, filter => 0, auto => 1, ); And then somewhere else: eval{ $obj->validate() }; if( my $results = $EVAL_ERROR ){ ... } METHODS validation __PACKAGE__->validation( module => 'FormValidator::Simple', profile => { ... }, filter => 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. Expects either a HASHREF or a reference to a subroutine. If it's a subref it will be passed the result row object as it's first parameter so that you can perform complex data validation for cases when you'd like to have access to the actual result. For example, you could use the following to return an error if the named field is not unique in the table: my $profile = sub { my $result = shift @_; return { required => [qw/email/], constraint_methods => { email => sub { my ($dvf, $val) = @_; return $result->result_source->resultset->find({email=>$val}) ? 0:1; }, }, }; }; Please note that the subref needs to return a hashref/arrayref suitable for use in the validation module you have chosen. 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". (The "valid()" method must return an ARRAY reference or HASH reference.) 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 SEE ALSO "DBIx::Class", "FormValidator::Simple", "Data::FormValidator" AUTHOR Aran C.
