NAME

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

VERSION

       version 0.40013

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 satisfed 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 the FH Moose Type, 'email'.

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