data.on_delete_required

Reference does not say what deleting its record does.

Area 5, Data; not declinable; the next step is usually the human's.

error: `Todo.owner_id` doesn't say what deleting its `User` does --> main.jadpo:7:5  |7 |     owner_id: User.id  |     ^^^^^^^^ refers to a `User`  reason: Any field typed `User.id` is a reference with a foreign key, and its block must say what happens when the `User` is deleted: `OnDelete.restricted` refuses the delete, `OnDelete.cascade` deletes this record too, and `OnDelete.cleared` sets an optional reference to `none`. There is no default.  next: Add `on_delete:` to `owner_id`'s block (human)  rule: data.on_delete_required  help: https://jadpo.dev/docs/errors/data.on_delete_requiredcheck failed: 1 error, 1 file
