Assignee: Nikita Timofeev
> Mapping Proposal: replace "toDepPk" with "fk"
> ----------------------------------------------

> Key: CAY-2739
> URL: https://issues.apache.org/jira/browse/CAY-2739

> Issue Type: Improvement
> Reporter: Andrus Adamchik

> Priority: Major
> Time Spent: 10m
> Remaining Estimate: 0h
>
> "toDepPk" is a DbRelationship property that hints that Cayenne should take
> the value of the join on the source side and propagate it to the target side.
> It only applies to PK-to-PK relationships.
> It is an artificial construct with nothing equivalent on the DB side, so it
> may be confusing as to what it means. Moreover it is limited to PK-PK
> relationships, meaning that we can't propagate values if the source is not a
> PK.
> I suggest that we replace "toDepPk" with a complementary "fk" property that
> is both well-understood and equally applies to every relationship. "toDepPk"
> will be a special case of "fk=false" relationship. In most cases it can be
> auto-calculated (if one side is a PK, and another one is not), so hopefully
> it will not create extra mapping work.
