Sculptor adds id to all persistent DomainObjects and assumes in the
generation phase that an id attribute exists. I think it is tricky to
support your request in a general manner, foreign keys etc, but if you have
a specific exception it might be possible, but that depends on what you
need.
Starting point...
1. Skip id attribute in the transformation for some DomainObjects. Use AOP
as I described for the first question.
around transformation::Transformation::modifyIdAttribute(DomainObject
domainObject) :
if domainObject.name != "NoIdEntity" then ctx.proceed();
2. Adjust generation templates. Use AOP, add AROUND advices in
src/main/resources/templates/SpecialCases.xpt in your target project.
«AROUND templates::Hibernate::id FOR DomainObject»
«IF getIdAttribute() == null -»
<id />
«ELSE -»
«targetDef.proceed() »
«ENDIF -»
«ENDAROUND»
Let me know if you need some adjustments to Sculptor to support your case.
