Heyo, let assume I have 2 resources user and report, report has 2 relation to the user - editor and viewer. I create relationship report:report_id_1#editor@user:user_id_1 and everything is fine. How I should change relationship from editor to viewer? Should I use DeleteRelationships and then WriteRelationships? What if I have more relation like manager, editor, viewer, blocked etc, specific report should have only one relationship with specific user.
