If I create a nullable relation alongside the main entity, is there a way for it to be marked as non-null when returning it? e.g.

model Author {
  name String
}

model Book {
  author Author?
}

const book = await this.prismaService.book.create({
  include: {
    author: true,
  },
  data: {
    author: {
      create: {
        name: 'Bob',
      },
    },
  },
})

In the above example,

book.author

is nullable, yet that the fact that that function succeeded and is returning data means that that field will never be null Is there an existing way to get

book.author

back as a non-nullable value, or should I create a feature request on GitHub for this?

@Ben Ezard 👋 You can create a request here but I don’t think that it’s possible to change the types at runtime via TypeScript. as the author

create

that you’re providing is optional.
