do I really have to write updateAddress separately? Or is there a way for nested updates?

You could use a nested mutation, like:

mutation {
  updateUser(
    data: {
      address: {
        update: {
          data: {
            ...
          }
          where: {
            ...
          }}
      }
    }
  )
}

hmm, thanks, seems I’ve missed this part in the tutorials 🙂

No worries. Glad, I could help 🙂

@andre do you perhaps have some links to any docs on the above?

@Josef Henryson Sure, https://www.prismagraphql.com/docs/reference/prisma-api/mutations-ol0yuoz6go#nested-mutations

is this only for prisma, or is it valid even for graphcool service?

I think it is Prisma exclusive.
