Is it possible to limit the number of relations for an object

[alepillerBIM]

Hello,

I made some experimentation with OpenFGA and I didn't find any way to limit the number of relation to only one.

For exemple this simple model :

model
  schema 1.1

type user

type BACSpace
  relations
    define admin: [user]
    define editor: [user] or admin
    define viewer: [user] or editor

I can create a relation admin and editor and viewer at the same time though the api of OpenFGA. I don't want because because there is inheritance between relations.

Do you know a way to avoid this ?

Have a good day.
