Cascade delete

On a 1-to-1 or 1-to-many relationship:

• Delete children when parent is deleted
• Do not delete children when they are removed from parent relation

Usage

• Use beforeOperationDeleteOne({ ref: "<child ref>" }) for one-to-one relationships and beforeOperationDeleteMany({ ref: "<child ref>" }) for one-to-many relationships
• The ref value must be the same as the ref config of the relationship field
• Add it as a before operation hook to relationship fields you want to cascade delete

Example

See testSchema/cascadeDelete/oneToOne.ts and testSchema/cascadeDelete/oneToMany.ts.
