Cruisecontrolrb users - Mar 2007 - build failing because of foreign keys

Hi,
I''m trying to build my rails project but it keeps failing. All the
tests pass from the work folder though when I run them from the
command line.  All the error messages in the build log center around
foreign keys. Errors such as this:
Message: ActiveRecord::StatementInvalid: Mysql::Error: Cannot delete
or update a parent row: a foreign key constraint fails
>From reading the manual, I imagine I need a custom
''cruise'' task in
order to get this to work, but I''m not sure what to put in it.

Any help would be greatly appreciated.
thanks,
Chris
