Prisma1: Extends Type

[Fi1osof]

Feature Request

What feature are you missing?
Extend generated types in server/src/schema.graphql

How could this feature look like in detail? Tradeoffs?
Example in apollo: https://www.apollographql.com/docs/graphql-tools/generate-schema.html#extend-types

const typeDefs = [`
  schema {
    query: Query
  }
  type Query {
    bars: [Bar]!
  }
  type Bar {
    id
  }
  `, `
  type Foo {
    id: String!
  }
  extend type Query {
    foos: [Foo]!
  }
`]

I see no reason why this wouldn't work. Have you tried it?

[Fi1osof]

Yes, i tried and it does not work. No errors, just no extends.

[marktani]

Can you share a minimal setup that showcases the unexpected behaviour?

[Fi1osof]

@marktani
In prisma schema
`type Extended {
id: ID! @unique
field1: String
}

extend type Extended {
field2: String
}`

Expected Extended.field2 too, but got only

type Extended
implements Node {
  id: ID!
  field1: String
}

In src/schema.graphql it does not works too.

I am trying this, which does not work.

prisma.graphql

type Player implements Node {
  id: ID!
  firstName: String!
}

schema.graphql

# import Player from "./generated/prisma.graphql"

type Query {
  players: [Player!]!
}

extend type Player {
  signedByUser: Boolean
}

Query returns 400 error

query PlayersQuery {
  players {
    id
    firstName
    signedByUser
  }
}

Running into the same issue:

# import Query, User from "./generated/prisma.graphql"

type Query {
  me: User
}

extend type User {
  authToken: String
}

Trying to add on authToken to the User type, but then when I try to grab it I get the message of Cannot query field "authToken" on type "User". Did you mean "{similar field here}"?

Still actual

This is a feature request to the respective GraphQL server library you're using, not to Prisma.
Please open a new feature request at the corresponding GitHub repository.

Thanks! 🙌

@marktani, maybe I do not understand what? Prisma uses prisma-binding. Prisma-binding uses graphql-tools. Graphql-tools says it is working https://www.apollographql.com/docs/graphql-tools/generate-schema.html#extend-types
Why it does not working in prisma?
I sent similar issue a few days ago https://github.com/prisma/graphql-yoga/issues/430

[gkTim]

This issue still happens. The extension of the type is not included in the generated graphql schema when running prisma generate
