[Catalyst] Two ways to create record

[Alex Povolotsky]

Hello!

In Tutorial (BTW, "CRUD" section of tutorial lacks U completely), I've 
seen  this way of filling in the record:

    my $book = $c->model('GalleryDB::Gallery')->new({});
    $book->populate_from_widget($result);

In InstantCRUD data is filled in with

my $item = $result->save_to_db();

Can anyone experienced tell me about drawbacks of both ways to do create?

Alex.
