Looks like bug. Even if you try to use non ref data inside update,
column data didn't updated (actually updated, but not inflated data)
$foo->update({ ts => '2010-02-05' });
But this will do the trick:
delete $foo->{_inflated_column}{ts};
So, possibly this string should be placed into
DBIx::Class::Row::set_inflated_columns.
Here is patch (I use v0.082820):
$ cat Row.pm.patch

}
}
+ else {

}
$self->set_columns($upd);
}
