hello I have models like this

model Player {
  team Int[]
  monsters Monster[]
}

model Monster {
  id Int
  name String
}

model Player {
  team Int[]
  monsters Monster[]
}

model Monster {
  id Int
  name String
}

how do I select player.monsters where id is in player.team[] I tried

monsters: { where: { id: { in: player.fields.team } } }

monsters: { where: { id: { in: player.fields.team } } }

but that's throwing type errors

Hey 👋 Assuming your model looks something like this:

model Player {
  id       Int       @id @default(autoincrement())
  team     Int[]
  monsters Monster[]
}

model Monster {
  id       Int     @id @default(autoincrement())
  name     String
  Player   Player? @relation(fields: [playerId], references: [id])
  playerId Int?
}

model Player {
  id       Int       @id @default(autoincrement())
  team     Int[]
  monsters Monster[]
}

model Monster {
  id       Int     @id @default(autoincrement())
  name     String
  Player   Player? @relation(fields: [playerId], references: [id])
  playerId Int?
}

Would a script like this work for your usecase?

  const player = await prisma.player.findUnique({
    where: { id: playerId },
    select: { team: true },
  });

  const playerWithFilteredMonsters = await prisma.player.findUnique({
    where: { id: playerId },
    include: {
      monsters: {
        where: {
          id: {
            in: player.team,
          },
        },
      },
    },
  });

  const player = await prisma.player.findUnique({
    where: { id: playerId },
    select: { team: true },
  });

  const playerWithFilteredMonsters = await prisma.player.findUnique({
    where: { id: playerId },
    include: {
      monsters: {
        where: {
          id: {
            in: player.team,
          },
        },
      },
    },
  });

hello, thanks for getting back yeah, I was just wondering if it was possible to do this in a single query, but probably not

Nurul•2mo ago

For this case you would need to use two queries 👍
