"""OwnedMixin — adds owner_id to any model for row-level ownership.
|
|
|
|
Usage:
|
|
class Contact(Base, TenantMixin, OwnedMixin):
|
|
...
|
|
|
|
owner_id semantics:
|
|
- NULL → "tenant-owned" (visible to all with module permission)
|
|
- UUID → owned by that user (visible to owner + shared via entity_permissions)
|
|
- When creating: owner_id = current_user.id (set automatically by service layer)
|
|
- Transfer: only owner, admin, or system_admin can change owner_id
