Body
You can use use <code>HTML::FormHandler::Moose</code> and <code>HTML::FormHandler::Model::DBIC</code> and get some nice forms. As a simple example: The form definition: <pre><code>package MyStats::Form::Datetime ; use HTML::FormHandler::Moose ; extends 'HTML::FormHandler::Model::DBIC' ; use Date::Calc qw(Today_and_Now) ; has_field 'datetimeid' => ( label => 'ID' ) ; has_field 'datetime' => ( type => 'Text', apply => [ { transform => \&transform_dt } ] , deflation => \&deflation_dt , required => 1 ) ; has_field 'submit' => ( type => 'Submit' , value => 'Speichern' ) ; # These are the fields of the table datetime sub transform_dt { my ( $dt ) = @_ ; my @d = ( $dt =~ m/(\d{1,2})\.(\d{1,2})\.(\d{4})\s+(\d{1,2}):(\d{1,2})/ ) ; return sprintf( '%04d-%02d-%02d %02d:%02d:00' , @d[2,1,0,3,4] ) ; } sub deflation_dt { my ( $dt ) = @_ ; my @d = ( $dt =~ m/(\d{4})-(\d{2})-(\d{2})\s+(\d{1,2}):(\d{1,2})/ ) ; if( ! @d ) { @d = Today_and_Now() ; } return sprintf( '%02d.%02d.%04d %02d:%02d:00' , @d[2,1,0,3,4] ) ; } 1 ; </code></pre> And the usage in a controller: <pre><code>package MyStats::Controller::Datetime ; use Moose ; use namespace::autoclean ; BEGIN { extends 'Catalyst::Controller' ; } use MyStats::Form::Datetime ; has 'form' => ( isa => 'MyStats::Form::Datetime' , is => 'rw' , lazy => 1 , default => \&new_datetime_form ) ; sub new_datetime_form { MyStats::Form::Datetime->new( css_class => 'datetimeform' , name => 'datetimeform' ) ; } ... sub add :Local :Args(0) { my ( $self , $ctx ) = @_ ; my $data = $ctx->model( 'MyStatsDB::Datetime' )->new_result( {} ) ; $ctx->stash( template => 'datetime/add.tt2' , form => $self->form ) ; $ctx->bread_crumb( { name => 'Datum/Zeit eingeben' , location => '/datetime/add' } ) ; $ctx->req->param( 'datetimeid' , undef ) if $ctx->req->param( 'datetimeid' ) ; return unless $self->form->process( item => $data , params => $ctx->req->params ) ; $ctx->flash( message => 'Neuer Datensatz ' . $data->datetimeid . ' angelegt.' , id_add => $data->datetimeid ) ; $ctx->res->redirect( $ctx->uri_for( '/datetime' ) ) ; } ... __PACKAGE__->meta->make_immutable ; 1 ; </code></pre> Works good.

1. COThanks, but I was hoping to not have to specify {{datetimeid}} and {{datetime}} myself, but just point it at a database table and have it read the fields itself. And also turn varchar(32) into a text input field with length 32, etc.

2. CO@WillSheppard I'm not sure if something like this exists, but one could write something to generate the `HTML::FormHandler::Moose` files.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
