Module Version: 0.06   Source   Latest Release: DBIx-Class-HTMLWidget-0.16

NAME ^

DBIx::Class::HTMLWidget - Like FromForm but with DBIx::Class and HTML::Widget

SYNOPSIS ^

You'll need a working DBIx::Class setup and some knowledge of HTML::Widget and Catalyst. If you have no idea what I'm talking about, check the (sparse) docs of those modules.

   package My::Model::DBIC::Pet;
   use base 'DBIx::Class';
   __PACKAGE__->load_components(qw/HTMLWidget Core/);

   
   package My::Controller::Pet;    # Catalyst-style
   
   # define the widget in a sub (DRY)
   sub widget_pet {
     my ($self,$c)=@_;
     my $w=$c->widget('pet')->method('get');
     $w->element('Textfield','name')->label('Name');
     $w->element('Textfield','age')->label('Age');
     ...
     return $w;
   }
     
   # this renders an edit form with values filled in from the DB 
   sub edit : Local {
     my ($self,$c,$id)=@_;
  
     # get the object
     my $item=$c->model('DBIC::Pet')->find($id);
     $c->stash->{item}=$item;
  
     # get the widget
     my $w=$self->widget_pet($c);
     $w->action($c->uri_for('do_edit/'.$id));
    
     # fill widget with data from DB
     $item->fill_widget($w);
  }
  
  sub do_edit : Local {
    my ($self,$c,$id)=@_;
    
    # get the object from DB
    my $item=$c->model('DBIC::Pet')->find($id);
    $c->stash->{item}=$item;
    
    # get the widget
    my $w=$self->widget_pet($c);
    $w->action($c->uri_for('do_edit/'.$id));
    
    # process the form parameters
    my $result = $w->process($c->req);
    $c->stash->{'result'}=$result;
    
    # if there are no errors save the form values to the object
    unless ($result->has_errors) {
        $item->populate_from_widget($result);
        $c->res->redirect('/users/pet/'.$id);
    }

  }
