I just can't seem to get lists of scalars working in Prisma

that's a shame 🙂

Haha

what are you trying to accomplish and what's your current state? 🙂

I'm trying to store an array of strings on a record. I'm using the mysql connector. I thought it was possible to store a list of scalars, but I realize I'm missing something.

You can store a list of Strings. What's your datamodel, your mutation and any responses/error messages you receive?

On the type in Prisma datamodel.graphql:

type Game {
  description: [String!]!
}

In my schema.graphql file:

type Mutation {
  createGame(description: [String]!)
}

That sounds like a JS error. Does it work when directly running the mutation against the Prisma API?

Hmm I'll check

If yes, please share the debug output that contains the verbatim query sent to Prisma from

prisma-binding

(assuming you're using that)

Yes I'm using prisma-binding. It actually didn't work when testing directly against the Prisma API. I thought I got the format correct, but the error was

Expected 'GameCreatedescriptionInput', found not an object.

can you PM me your service information and the query that reproduces this?

Yes, just sent you the mutation. Will send the service info

Ah. Can you please check if adding an

id: ID! @unique

or any other field like

a: Int!

to

Game

fixes this?

The type already has an

id: ID! @unique

field

this is what you shared, was that only the short version?

type Game {
  description: [String!]!
}

Sorry, yes, heavily truncated 😕 I apologize! Just didn't want to share the huge type def here. I pm'd you the mutation, I'll pm you the type def in my datamodel.graphql file

ok, I'm not be able to take a deep look into this now, but it sounds like something unexpected in your datamodel which leads to an empty input type being generated (or another "degeneration" of the input type)

interesting. No problem, I appreciate you hopping in to help! I sent you everything via slack DM so you have it whenever you're able to take a look. Thanks again!

awesome, thanks! one other thought, can you check if this happens with a type that just has an id and a list of strings? Then this would be a super easy reproduction. Otherwise I'll take a look at your specific datamodel when I find the time 🙂

Good call, I will do that!

Keep in mind that scalar lists aren’t filterable yet though ! https://github.com/graphcool/prisma/issues/1275

@weakky ended up being programmer error 😞 Simply forgot the "set" field in the mutation being sent to Prisma. I swear I've read the docs completely, but I must have just missed that!

Aren’t you using Typescript generated definitions ?

No. I had everything configured correctly in my type defs, I just missed that detail in my resolver—I did not know what when I am storing an array of scalars, I need to map the field to an object with a "set" property that contains the array of scalars
