Here's what I came up with:
package HTML::FormFu::Plugin::IntervieweeEditLink;
use strict;
use base 'HTML::FormFu::Plugin';
sub post_process {
my ($self) = @_;
my $form = $self->form;
my $attached_field = $self->parent;
# don't want to add a link to the extra 'add interviewee' row
return unless $attached_field->value;
my $position =
$attached_field->parent->get_element({type=>'Hidden',
name=>$attached_field->name});
my $formfu = $attached_field;
while ( not $formfu->isa('HTML::FormFu') ) {
$formfu->can('parent') or die "no luck on finding the formfu object";
$formfu = $formfu->parent;
}
my $uri =
$formfu->stash->{context}->uri_for('/interviewee/edit/'.$attached_field->value);
my $link = qq{<a href="$uri">Edit Details</a>};
warn "trying to add $link";
$attached_field->parent->insert_after(
HTML::FormFu->new->element( {
type => 'Src',
content_xml => $link,
}),
$position,
);
}
1;
Like this in the yml:
- type: Block
tag: td
elements:
- type: Hidden
name: interviewee_id
plugins:
- IntervieweeEditLink
probably makes you want to gouge out your own eyes, but I'm working on
a deadline and it did the job.
