Any pointers / examples on how to write a test file?
I just added a test to t/88result_set_column.t in SVN to illustrate your
problem. It was a bit messy since SQLite doesn't actually barf, but it
should be okay. What DB are you using?
So you are saying that you cannot undo the prefetch?
If I do the following
---------------------
my $rs = $app->get_rs_with_prefetch();
$rs = $rs->search(undef,{prefetch=>undef});
my $item = $rs->next;
---------------------
Calling $rs->next still includes the prefetch columns.
That would simply merge undef with whatever the old prefetch clause was. To
clear prefetch entirely you would have to do $rs->{attrs}->{prefetch} =
undef, but you probably don't want to be doing that.
Fortunately, you shouldn't need to worry about it now since I've fixed the
problem. It'll be on CPAN with the next point release but it would be useful
if you could grab the latest version from SVN now and check to see if your
problem persists. You can get it like so:
svn co http://dev.catalystframework.org/repos/bast/trunk/DBIx-Class
