oy, i have two models, Vehicle and Driver. They are related by a one to one relation, which marks which car is currently occupied by wich driver. the relation is marked as optional on both ends. the problem i now face is that i can't create a vehicle, as i receive the following exception: "Null constraint violation on the fields: (

driverId

)". Do you know how i could approach this error?

Could you show us the schema?

sure

driverId

might need to be optional too 🤔

well, that does make sense 🙃. i'll try this out

no problem! glad I could help 🙂
