Does Drupal 8 support referential integrity? Can I tell Drupal what it should do if a parent row in a content type is deleted? For example:
- I could tell Drupal not to allow the deletion of a parent row if it has child rows
- I could tell Drupal to delete all child rows that belong to a parent row when that parent row is deleted
By row I mean an item of a content type. For example, if the content type is Book, a row is the data about one book.
