Change response field names

Problem

I’m trying to rename some fields when using select.

Suggested solution

This is my current query:

const data = await prisma.data_riskscores.findMany({
  select: {
    id: true,
    sections: true,
    configuration_country: {
      select: {
        id: true,
        name: true
      }
    }
  }
})

Now I’d like to rename sections and configuration_country, because the data should not necessarily reflect the naming scheme of the database (IMO these are very different usecases):

const data = await prisma.data_riskscores.findMany({
  select: {
    id: true,
    results: sections,
    configuration_country: {
      as: country,
      select: {
        id: true,
        name: true
      }
    }
  }
})

Alternatives

Using @map resp. rename the relation field. It’s a reasonable alternative, but I think the schema is not the right place to make this change. IMO, the schema should (more or less) reflect the database. Whereas the select statement should allow to change the response data (because that might differ depending on the context of my request). For now, I’d probably go with a raw query instead.

Another alternative inspired from JS destructuring renaming

const data = await prisma.profile.findMany({
  select: {
    id: true,
    name: true,
    configuration_country: 'country' // work like an 'as'
 }
})

But it won’t resolve the typed approach of Prisma

totally agreed,

Too sad to have to map:

    const invoices = await this.prisma.invoice.findMany({
      where: { AND: where },
      include: { client: true, _count: { select: { notes: true } } },
      orderBy,
    });
    return invoices.map(({ _count, ...invoice }) => ({
      ...invoice,
      count: _count,
    }));

Instead of simply have:

    return this.prisma.invoice.findMany({
      where: { AND: where },
      include: { client: true, _count: { select: { notes: true }, as: 'count' } },
      orderBy,
    });
