Hey, I would like to use relations as I am, coming from a mySQL environment, think it's the best approach. I checked out wesbos advanced react course and saw that he is not making use of relations: https://github.com/wesbos/Advanced-React/blob/master/finished-application/backend/datamodel.graphql (see cart). Anyways, are relations the way to go? I have items and users I wanna relate to each other. Moreover, I fail to find resources on how to handle the relations with prisma and graphql, anyone?
