create OR connect on nested writes (upsert)

[johanmic]

is there a plan to add an upsert to nested writes? The use case is when you dont know if the nested record exists or not

say im creating a movie with a list of n actors, some already exist and some do not.
using either create or connect wont work since i dont know beforehand which exist or not.

the only current solution is to loop and upsert the entire list and then always use connect.
so instead of connect, create also add an upsert

(pseudo ish)

const actors = [{name:'Johnny Dopp'}, {name:'Brad Pitts'}]

const actorIds = Promise.all(actors.map((actor)=>photon.artists.upsert({
    where: { name: actor.name },
    update: {},
    create: actor
  }))

photon.movie.create({
    name: "something",
    cast: {
      connect: actorIds.map(actor=>actor.id)
    }
  })

but instead

photon.movie.create({
    name: "something",
    cast: {
      upsert: [ 
          {name:'Johnny Dopp'}, 
          {name:'Brad Pitts'}
      ]
    }
  })

the first one is not very ACID obviously.

You can open an issue about this in the specs repo so that we can include it in the upcoming photonjs API changes: https://github.com/prisma/specs

Also, checkout photonjs spec: https://github.com/prisma/specs/tree/master/photonjs

Internal Note: We do have nested upsert but we only expose it within an update. Exposing this might be very simple. It is mostly writing a few test cases i assume.

[johanmic]

Any plans to implement this? @mavilein
it would be an amazing feature

[mavilein]

Just realized that we already have a more prominent issue for this feature request: prisma/prisma1#2194

[janpio]

That one is for Prisma1 though, which we do not look into around here ;)

[johanmic]

so a feature thats been requested since 2018 and might be very simple. sounds like a good candidate @mavilein :)

@jaywalklabs @mavilein @janpio Agree, this would remove a lot of boilerplate!

[johanmic]

@ssalbdivad not no mention actually support transactions which the boilerplate workaround does not.

[ManAnRuck]

this would be awesome when it works! 🤗

The connectOrCreate nested operation is available on dev and will land on stable with the next release (2.1.0).

Moved into separate issue #764 @RoaldSchuring
