NAME

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

VERSION

10       version 0.40068
11

SYNOPSIS

13       Manual Index
14
15       Cheatsheet for converting from Data::FormValidator.
16

DESCRIPTION

18       Information that's useful when switching from Data::FormValidator to
19       HTML::FormHandler. There's not a lot here yet, so if you have something
20       to add, patches are welcome.
21
22       In a general way, FormHandler doesn't have nearly so many "special"
23       checks as Data::FormValidator. It would be possible to implement many
24       of them, but there hasn't been much demand for them. So far FormHandler
25       users seem to be satisfied with the "do your own checks in a Perl
26       method" solution. Because of the greater complexity of FormHandler's
27       data model - with Repeatable arrays and nested compounds, etc - it's
28       somewhat harder to do some of them automatically.

Differences/conversions

31       dependencies
32           In FormHandler, 'dependency' is the equivalent of
33           'dependency_group', without the key names.
34
35           The other variations of dependencies in DFV are not implemented in
36           FormHandler, and would normally be done in a form's 'validate' sub.
37
38       trim, filters
39           A 'trim' filter is installed by default in FormHandler; it's a
40           special version of an apply action, and can be set to a transform
41           or Moose type. See the documentation in
42           HTML::FormHandler::Field#trim.
43
44           Transforms and inflations/deflations do not change what is
45           presented in the form unless you set the 'fif_from_value' flag on
46           the field.
47
48       FV_length_between, FV_max_length, FV_min_length
49           Use text fields with 'minlength' and 'maxlength' attributes.
50
51       FV_eq_with
52           Perform your own checks in the form 'validate' sub.
53
54               sub validate {
55                   my $self = shift;
56                   if( $self->field('one')->value eq $self->field('two')->value ) {
57                   }
58               }
59

Constraints

61       The simple constraints from Data::FormValidator::Constraints can be
62       used directly in a FormHandler form:
63
64           use Data::FormValidator::Constraints ('match_state');
65           has_field 'my_state' => (
66               apply => [ { check => \&match_state, message => 'Invalid State' } ] );
67
68       email
69           Use the 'Email' field type, or use the FH Moose Type, 'email'.
70
71                has_field 'email' => ( type => 'Email' );
72                -- or --
73                use HTML::FormHandler::Types ('Email');
74                has_field 'email' => ( apply => [ Email ] );
