Hi Carl,
I just plays with FormFu to find solution of my problem.
There is example what I want:
1) I want use DBIx::Class for model
2) I want use DBIx::Class::Validation as model validator
This points I have done and checked in my example:
package pf2::Schema::Result::Switch;
use strict;
use warnings;
use base 'DBIx::Class';
__PACKAGE__->load_components(qw/Core Validation/);
__PACKAGE__->table("switch");
#<there is my class definition>
#thee is my Validation profile which must check 'name' field for UNIQUE in
`switch` table;
#in example used FormValidator::Simple::Plugin::DBIC::Unique;
use FormValidator::Simple qw/DBIC::Unique/;
$DBIx::Recordset::PreserveCase = 1;
my $profile = sub {
my ($result) = @_;
return [
name => [[ 'DBIC_UNIQUE', $result->result_source->resultset,
'name']],
];
};
__PACKAGE__->validation(
module => 'FormValidator::Simple',
profile => $profile,
filter => 0,
auto => 0,
);
#----------------------------
When I use FormFu i do
if($form->submitted_and_valid){
$form->model->update($switch);
} else {
$form->model->default_values($switch);
}
So in my point of view inside submitted_and_valid must be DBIC validation
too (fill some $_switch object and call $_switch->validate();)
In case of errors they must be added as exceptions and properly displayed on
form.
I just play around and tried to implement it by inheritance of FormFu but
yet have problems with adding exceptions to the form...
in controller i will use next code
if($form->model('DBIC::Validated')->submitted_and_valid($switch)){
$form->model->update($switch);
} else {
$form->model->default_values($switch);
}
Also did some own class based on 'HTML::FormFu::Model::DBIC';
package HTML::FormFu::Model::DBIC::Validated;
use strict;
use warnings;
use base 'HTML::FormFu::Model::DBIC';
use Data::Dumper;
use Carp qw( croak );
our $VERSION = '0.00001';
$VERSION = eval $VERSION;
sub submitted_and_valid{
my ($self, $dbic) =...@_;
croak "row object missing" if !defined $dbic;
my $form = $self->form;
return undef unless $form->submitted();
my $form_submitted_and_valid = $form->submitted_and_valid();
HTML::FormFu::Model::DBIC::_save_columns($form, $dbic, $form ) or
return;
eval { $dbic->validate() };
return $form_submitted_and_valid unless my $dbic_validation_result = $@;
return $form_submitted_and_valid unless
$dbic_validation_result->has_error;
my $errors ={};
foreach my $key ( @{ $dbic_validation_result->error() } ) {
my $comma = '';
foreach my $type ( @{ $dbic_validation_result->error($key) } ) {
$errors->{$key} .= $comma."invalid: $key - $type ";
$comma = ','
}
}
foreach my $field ( @{ $form->get_fields } ){
my $name = $field->nested_name;
next unless defined $errors->{$name};
#PROBLEM A
# there I have problem with adding error message on form element yet
my $error = HTML::FormFu::Exception::Validation->new({message
=>'must be unique'});
#$error->validator($v);
#push @{$field->_validators}, $error;
$field->add_error($error);
}
return $form_submitted_and_valid &&
!$dbic_validation_result->has_error();
}
1;
Maybe it is a little brutal solution as soon as i not fully investigated
FormFu inside but in case if i can add on form field my custom message in
PROBLEM A then i have acceptable solution for my task...
