[dancer-users] updating a form

Hi,
I’m trying to build a small app to comment on images. Probably I’m almost there but currently stuck with updating a ‘file.yml' by a html-form.
I’ve made two routes (shown below) “get ‘/:id/edit’ for showing the form with the particular image to comment on. When hitting save the ‘post ‘/edit’ will be called. My problem is that the post route doesn’t have the $id initialised. Is there someone around who can tell me how to solve this or point to me what I’m doing wrong?
Thanks,
Gert
The structure is an AoH.
The file.yml is like
---
- collection: ''
description: good
id: 0
imgf: photo.jpg
tags: ''
- collection: ''
description: ''
etc..
————end of yaml
#---------------------------------------------------------------------
#
# get EDIT
#
#---------------------------------------------------------------------
get '/:id/edit' => sub {
my $filename =
Dancer::FileUtils::read_file_content(
Dancer::FileUtils::path( setting('appdir'), 'myImages.yml' ) );
my $data = from_yaml $filename;
my @data = @{$data};
#print Dumper \@data;
my $id = param('id');
template 'edit', { data => $data[$id], id => $id, };
};
#---------------------------------------------------------------------
#
# post EDIT
#
#---------------------------------------------------------------------
post '/edit' => sub {
my $data = get_AoH_imagelist();
my @data = @{$data};
my $id = param('id');
$data[$id] { description}= params->{description} ;
#$data[2] { description}= params->{description} ;
# this works but then all descriptions end up in the third group of hashes.
my $filename = "myImages.yml";
write_file $filename, to_yaml($data);
redirect '/';
};
