CQL::ActiveRecord::Dependents
Overview
Applies the dependent: strategies of a model's associations when a record is deleted.
has_many and has_one register an association when it declares dependent:;
many_to_many always registers one, so deleting a record removes its join rows.
A restrict_with_error association is checked before anything is deleted; the others
run in declaration order, in the same transaction as the record's own delete.
