Where I am lost is, how do I reference this kind of type:

LineItemCreateManyWithoutInvoiceInput

That looks, to me, to be a custom input-type that he created.

Na it’s a generated schema in Prsma

Aaah, yeah - I saw that after I sent 🙈 I've got no clue then. I've not gotten this far in my Prisma-journey yet.

😂 thanks man

Just tried to generate this and I found the

LineItemCreateManyWithoutInvoiceInput

.

type Invoice @model {
  id: ID! @unique
  lineItems: [LineItem!]! @relation(name: "InvoiceItems")
}

type LineItem @model {
  id: ID! @unique
  invoice: Invoice! @relation(name: "InvoiceItems")
}

on line nr. 189 in the generated

schema.graphql

.

@Jenkins wow how did you generate that? My generated folder only has index.ts and prisma-schema.ts

I used the graphql-cli, but you can also use Prisma's generate. Under

generate:

in

prisma.yml

, add:

- generator: graphql-schema
  output: ./path/to/generated

hahah yeah. I am using:

- generator: typescript-client
    output: ./generated/prisma-client/

That's because you can't import that from a ts file. You need to generate the schema using what I wrote above and then you can import using the

# import x from "schema.graphql"

.

thanks a lot. I got it now. Do you know the difference between the two — ts and graphql.

Yeah, the generator for typescript-client generates the client you use to interact with Prisma. Because TypeScript needs everything statically typed, the generated client holds all the type-information from your

datamodel.prisma

. Then, for either GraphQL-Yoga(which I'm guessing you're using) or ApolloServer, you need a

schema.graphql

. If you wanted to just directly expose your API to the world you could use said file in the

typeDefs

of the constructor. But most likely, especially with mutations, you want to hide certain parts. So that's when you create your own schema.graphql that you use with your server. To make it easy to reuse your models (Product, User, etc...) you can import them directly to your custom one from the generated. That way they're always in sync between your

datamodel.prisma

,

./generated/schema.graphql

and

./schema/my_custom_schema.graphql

. Makes sense? 🙂

Now you have made someone’s day — mine. Thank you so much for helping out.

My pleasure 🦜
