For the foreign key reference column name, I didn't realize you could assign
those column names. Worked like a charm.

To customize the auditable columns, I added the following to my
SpecialCases.ext:
Entity myAddAuditable(Entity entity) :
addAuditable(entity) ->
entity.attributes.select(a | a.name ==
'createdBy').setDatabaseColumn('CREATED_BY') ->
entity.attributes.select(a | a.name ==
'lastUpdated').setDatabaseColumn('LAST_UPDATED_DATE') ->
entity.attributes.select(a | a.name ==
'lastUpdatedBy').setDatabaseColumn('LAST_UPDATED_BY') ->
entity.attributes.select(a | a.name ==
'createdDate').setDatabaseColumn('CREATED_DATE');
Entity addAuditable(Entity entity) :
JAVA
org.fornax.cartridges.sculptor.generator.util.GenerationHelper.addAuditable(sculptormetamodel.Entity);

As far as the UUID attribute, I guess what I really want to do is get rid of
the natural key altogether and just use the surrogate key for this
particular table.
I tried overriding the modifyUuid extension to not generate the UUID
attribute at all via:
modifyUuid(DomainObject domainObject) :
null;
But the UUID attribute was still generated for some reason. For now I'm
keeping a natural key in this table although I don't really need it.
I ran into something else which I want to check whether is a bug or working
as intended... I have a persistent entity class A which has a collection of
non-persistent value objects B. Class B has a reference to Class C, which
IS persistent.
The hibernate mapping and table for B are not generated (good), but the
hibernate mapping for class A has a reference to class B, which causes an
error because class B isn't a persistent entity.
I didn't see a way to specify the reference from A to B should be
non-persistent. Am I missing something?
Ex:
Entity A {
- Set<@B> bs
}
ValueObject B {
not persistent
- @C c
}
Entity C {
}
