[Catalyst] Relationship layout

[Will Smith]

Hi,
I tried the example. And get this error when doing the
has_a relationship.
-----------
Artist can't load CD: has_a needs a valid column at
/usr/lib/perl5/site_perl/5.8.5/Class/DBI/Relationship/HasA.pm
line 12
-----------
I don't understand why I get this error, even though I
check the column name of table cd, which is a foreign
key of artist.

Please show where is my mistake.

Thanks
