prisma relations generated types

So I've ran to a problem where the generated types from prisma don't include my relationships, I've googled a bit more and saw this was an issue for many people but not many people have any answers at all, wondered if anyone here know how to deal with this? I've tried creating my own type with the prims getPayload and including my relationships but when fetching data it is automatically refering to the generated prisma types and I cant go around hardcoding that everywhere it seems like a bad idea... Trying to deploy and it keeps failing because of that 😦

Same thing on the prisma docs with more examples https://www.prisma.io/docs/concepts/components/prisma-client/advanced-type-safety/operating-against-partial-structures-of-model-types

This page documents various scenarios for using the generated types from the Prisma namespace

Yes I've read that and used that but on someplaces in my code, the return type of my data is more complex and it's using the generated types by prisma anyways so it doesn't solve that

It still searches for types from prisma

anyone? 😐

How about using type inference based on the function you’re using which fetches the row + relationships?

What do you mean?

function getBooks() {
  return prisma.books.findMany({ include: { author: true } })
}

type BooksWithAuthor = Awaited<ReturnType<typeof getBooks>>

function getBooks() {
  return prisma.books.findMany({ include: { author: true } })
}

type BooksWithAuthor = Awaited<ReturnType<typeof getBooks>>

Something like this

I had to fix my function return value, it was a problem there, which is weird because the type is the same
