You've got the right idea, but the wrong syntax. Try this:
$iterator =
A::Manger->get_objects(
require_objects => [ 'b.c' ],
query =>
[
'data' => { regexp => 'blah' },
'b.data' => { regexp => 'blah2' },
'b.c.data' => { regexp => 'blah3' },
]);
IOW, since you're making a call using the A manager and A is the primary
table, all related objects are addressed "starting from" a relationship in
A.
The chaining syntax is described in the get_objects() docs under the "query"
parameter:
http://search.cpan.org/dist/Rose-DB-Object/lib/Rose/DB/Object/Manager.pm#que
ry
Same deal for the require_objects parameter and docs.
