Manual IndexCheatsheet 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' } ] );
-
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 ] );
