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
