Connected fields do not get an updated by @updatedAt

[Sytten]

Bug description

Consider the following query:

await app.prisma.account.create({
    data: {
      name,
      tokens: {
        connect: tokens.map(t => ({ id: t.id })),
      },
    },
  })

with the following schema:

model Account {
  id         String         @id @default(cuid())
  tokens     Token[]
  updatedAt  DateTime       @updatedAt
}

model Token {
  account      Account? @relation(fields: [accountId], references: [id])
  accountId    String?
  id           String   @id @default(cuid())
  updatedAt    DateTime @updatedAt
}

One would expect that the updatedAt of the Token model would get updated on connect, but it is not the case. The following SQL is executed:

 UPDATE "public"."Token" SET "accountId" = $1 WHERE "public"."Token"."id" IN ($2,$3)

I can confirm the behavior. We should fix this as write does happen on the token table.

This has been resolved in prisma/prisma-engines#1465 and should be part of our next release -- thanks again for reporting @Sytten!
