DBIx::Class and Koha

I did some work today with DBIx::Class and Koha, and got opac-account.pl partially using it.

You can see the schema here and I had to make a few changes to C4::Context, and a few to opac-account.pl.

Here is what they were.

++my $borr = $rs->first;

++warn Dumper $borr;
my @bordat;
--$bordat[0] = $borr;
++push @bordat,$borr;

$template->param( BORROWER_INFO => @bordat );

So not many changes at all, i’ll work on changing some more, but it looks like adding DBIx::Class can be done in a gradual way.
