This is really a DBIx::Class question and belongs on that list.

However.. you perform update on a resultset. $c->model() returns a resultset with no where clause. So get the resultset that you need with search and then call update() on that.

$c->model('DB::Test')->search({ 'id' => $c->user->get('id') })->update({'lang' => $lang->first->id});
