Relation two to many with Prisma - prisma

Question

I'm trying to create a prisma schema with this kind of relation - I have two models: Player and Game. Every game is "played" by two players and I'm trying to connect them with something like this:
model Player {
id String #id #default(cuid())
name String
games Game[]
}
model Game {
id Int #id #default(autoincrement())
player_1 Player
player_2 Player
winnerId String
}
In this case I get an error which says Ambiguous relation detected. The fields player_1 and player_2 in model Game both refer to Player. Please provide different relation names for them by adding #relation(<name>).
And if I add relation with names which looks like this:
player_1 Player #relation(name: "GamePlayer1")
player_2 Player #relation(name: "GamePlayer2")
I get an error The relation field player_1/player_2 on Model Game is missing an opposite relation field on the model Player. I don't think that adding additional fields to Player model is necessary and also don't think that adding many to many relation which would look like this players: Player[] is smart.
What would be the right way to connect those two models based on my example?

Answer 1

You need to provide both player's id on Game and separate relation name on Player and Game. Here the right way to fix it:
model Player {
id String #id #default(cuid())
name String
games_player_1 Game[] #relation(name: "GamePlayer1")
games_player_2 Game[] #relation(name: "GamePlayer2")
}
model Game {
id Int #id #default(autoincrement())
player_1_id String
player_2_id String
player_1 Player #relation(name: "GamePlayer1", fields: [player_1_id], references: [id], onDelete: Cascade)
player_2 Player #relation(name: "GamePlayer2", fields: [player_2_id], references: [id], onDelete: Cascade)
winnerId String
}
