Support for Compositions

[gsvarovsky]

Compositions. How do we mark an object property as a composition, so that deletes are cascaded?

Good question. If a relation is defined using a property attribute, perhaps this can be added as an argument, e.g.:

class Notebook {
// ...
 var notes: Note[]
}

class Note {
// ...
 @MeldField("notebookId", onDelete: .cascade)
 var notebook: Notebook
 var notebookId: String
}
