    Hi,

    Is it possible to map fake foreign keys with CM?

    In many DBs for webapps there seem to be quite a few tables (for entities like Tags, Comments, Attachments, Events) to have relationships to many other tables, and instead of a FK, a combination of two fields is used (target_table_name and target_row_id).

    I know that other ORMs (like ActiveRecord from RoR) have this feature, but I'm not sure about Cayenne.

    Thanks in advance,

    George.
