Cascading Deletes

You can have a parent cascade delete its children by doing:


You can also use database foreign key cascades, but using the domain-level cascadeDelete will mean that any application-layer hooks/validation logic/etc. that might need to run due to the review being deleted will be run during em.flush().

Currently, Joist does not automatically cascade delete children; i.e. it could/may eventually use the database metadata of a foreign key with ON CACADE DELETE to know it should generate a cascadeDelete(...) in the base codegen file, but for now you have to manually specify any cascade deletions that you want.
