Hello @ekrueger and all. I am glad to inform you that starting from version 3.1.15 we now have the setRelation1to1 available. You can see more about it in the documentation page here: setRelation1to1 | Grocery CRUD - A PHP CRUD Generator Library
@ekrueger I’ve got your email but didn’t have time to check, will do that the soonest possible but very possible that this will be next weekend
