error: `Todo.project_id` can't be cleared --> main.jadpo:8:20 |8 | on_delete: OnDelete.cleared | ^^^^^^^^^^^^^^^^ the field can't be `none` reason: `OnDelete.cleared` sets the reference to `none` when the `Project` is deleted, which only an optional reference (`Project.id?`) can hold. next: Make it `Project.id?`, or use `OnDelete.restricted` or `OnDelete.cascade` (agent) rule: data.cleared_required_reference help: https://jadpo.dev/docs/errors/data.cleared_required_referencecheck failed: 1 error, 1 file
