Is there a way to rename a named relations? e.g. original:

type User {
  id: ID! @unique
  name: String!
  posts: [Post!]! @relation(name: "UserOnPost")
}

type Post {
  id: ID! @unique
  title: String!
  user: User! @relation(name: "UserOnPost")
}

changed datamodel:

type User {
  id: ID! @unique
  name: String!
  posts: [Post!]! @relation(name: "PenisOnPost")
}

type Post {
  id: ID! @unique
  title: String!
  user: User! @relation(name: "PenisOnPost")
}

I keep getting

✖ You are creating a required relation, but there are already nodes that would violate that constraint.

when

prisma deploy

Okay, maybe you have to use the @rename annotation

@rename

works when renaming the field e.g.

user

->

doctor

but I cannot figure out how to use for the relation name

I think i understand the problem. Normally prisma would delete the old relation and create the new one (with the new name)

genau 🙂

But you marked the relation as not nullable - so a post always has to have a user

but I think expected behavior is that it simply renames?

yes, seems like a missing feature
