I’m having an issue where my prisma schema gets updated every time I introspect, here’s the workflow: 1. I make changes to my db with plain sql 2. I introspect my db 3. Prisma schema gets generated 4. I update some values for easier understanding to the prisma client 5. I introspect again 6. Prisma schema gets updated again (overwriting my custom field changes) Here’s an example: Generated by prisma after introspect:

model Tag {
  id      Int       @id @default(autoincrement())
  name    String    @unique
  post    Post[]    @relation("post_to_tag")

  @@map("tag")
}

Modified my by afterwards:

model Tag {
  id      Int       @id @default(autoincrement())
  name    String    @unique
  posts   Post[]    @relation("post_to_tag")  <-------- posts instead of post

  @@map("tag")
}

Introspects again and overwrites my changes with the 1st code block again. Any idea why this could be happening? 🙂

Hey @bntzio 👋 Yes unfortunately this is a bug currently and we are working on this one 🙂

@bntzio Which version of Prisma are you using?

@Daniel Norman 2.12.1

Hey @bntzio, what you’re trying to do should already work. Introspect should retrieve your manually changed names from previous schema and keep them. So what you’re seeing looks like a bug, maybe caused by the combination with @@map on the model. I’ll open an issue to test and possibly fix this.

Hey @do4gr thanks! I just tried again without the mapping and it’s still changing my schema

Hey, thanks for trying that. I can also reproduce it locally, so no need for you to try more. You can follow the linked issue to be notified once it is fixed.

Awesome thanks @do4gr!
