[html-formfu] applying a filter

[Octavian Râşniţă]

I found a good solution for that, not by using a filter, but a transformer.

But it can be done directly without creating a custom module, like:

<element>
type Password
name password
label_xml Password<sup>*</sup>:
filter TrimEdges
constraint Required
<transformers>
type Callback
callback Digest::SHA1::sha1_hex
</transformers>
</element>

The method Digest::SHA1::sha1_hex can be used directly as a callback method.

I wrote my own Filter

lib/HTML/FormFu/Filter/myApp/Digest_SHA.pm

package HTML::FormFu::Filter::myApp::Digest_SHA;
use strict;
use warnings;
use base 'HTML::FormFu::Filter';
use Digest::SHA qw/sha1_hex/;

sub filter {
    my ( $self, $value, $params ) = @_;
    return sha1_hex($value);
}

1;

and in my create.yml

    - type: Password
      name: password
      filters:
        - type: "myApp::Digest_SHA"


works fine, but since I also use the repeat_password constraint and
the filter is applied before passwords are compared I will not use
this approach and rather change the password prior to
updating/inserting into the database.
