NAME

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

VERSION

       version 0.40068

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 ] );
