HTML::FormHandler::ManUser:Contributed PeHTML::FormHandler::Manual::FromDFV(3)

NAME
       HTML::FormHandler::Manual::FromDFV - converting from
       Data::FormValidator

VERSION
       version 0.40067

SYNOPSIS
       Manual Index

       Cheatsheet for converting from Data::FormValidator.

DESCRIPTION
       Information that's useful when switching	from Data::FormValidator to
       HTML::FormHandler. There's not a	lot here yet, so if you	have something
       to add, patches are welcome.

       In a general way, FormHandler doesn't have nearly so many "special"
       checks as Data::FormValidator. It would be possible to implement	many
       of them,	but there hasn't been much demand for them. So far FormHandler
       users seem to be	satisfied with the "do your own	checks in a Perl
       method" solution. Because of the	greater	complexity of FormHandler's
       data model - with Repeatable arrays and nested compounds, etc - it's
       somewhat	harder to do some of them automatically.

Differences/conversions
       dependencies
	   In FormHandler, 'dependency'	is the equivalent of
	   'dependency_group', without the key names.

	   The other variations	of dependencies	in DFV are not implemented in
	   FormHandler,	and would normally be done in a	form's 'validate' sub.

       trim, filters
	   A 'trim' filter is installed	by default in FormHandler; it's	a
	   special version of an apply action, and can be set to a transform
	   or Moose type. See the documentation	in
	   HTML::FormHandler::Field#trim.

	   Transforms and inflations/deflations	do not change what is
	   presented in	the form unless	you set	the 'fif_from_value' flag on
	   the field.

       FV_length_between, FV_max_length, FV_min_length
	   Use text fields with	'minlength' and	'maxlength' attributes.

       FV_eq_with
	   Perform your	own checks in the form 'validate' sub.

	       sub validate {
		   my $self = shift;
		   if( $self->field('one')->value eq $self->field('two')->value	) {
		   }
	       }

Constraints
       The simple constraints from Data::FormValidator::Constraints can	be
       used directly in	a FormHandler form:

	   use Data::FormValidator::Constraints	('match_state');
	   has_field 'my_state'	=> (
	       apply =>	[ { check => \&match_state, message => 'Invalid	State' } ] );

       email
	   Use the 'Email' field type, or use the FH Moose Type, 'email'.

		has_field 'email' => ( type => 'Email' );
		-- or --
		use HTML::FormHandler::Types ('Email');
		has_field 'email' => ( apply =>	[ Email	] );
