如何在prisma中使用带有外键的createMany？

model User {
  id    Int     @id @default(autoincrement())
  name  String
  posts Post[]
}

model Post {
  id      Int    @id @default(autoincrement())
  title   String
  content String
  userId  Int
  user    User   @relation(fields: [userId], references: [id])
}

const user = await prisma.user.findUnique({
  where: { id: userId },
});

const postsData = [
  { title: 'Post 1', content: 'Content 1', userId: user.id },
  { title: 'Post 2', content: 'Content 2', userId: user.id },
  // ...
];

const createdPosts = await prisma.post.createMany({
  data: postsData,
});
