Import Enum from my TS to the schema

Hey, Wanted to know if it's possible to import an enum inside my schema.prisma file instead of defining it inside ? Because all my types used by both front & back are located to a dedicated package, and it actually force me to define my enum in 2 distinct places, where I would like to only have it in my types package. Thanks!

Export client types in custom package

Hi, Actually I have a project in a monorepo, with a app/ folder and api/ folder. My API folder contain a node project that runs a web server, and also contains my prisma install. Now that i'm setting up the front, I would like to use the sames types as my back, but can't see a good solution to to that. My goal would be to have a types/ folder at the same root as my both projects, that is literally a node_module that contains all types that i want to use across projects. I tried to create a 2nd Prisma client that generate inside this folder, but when I try to build my package with a simple file that `export * from "myCustomPrismaClientPath/index", it throw me a lot of typescript error because it can't find packages like @babel/types or "undici-types". Do you guys have any idea or suggest to fix that ?

Extend client Type loose relation

Hey there, i'm having some trouble when I extend a Prisma client type (in typescript). I have a User, which have a oneToOne relation with a Preferences model, looking like that:

model User {
    id                 String                   @id @default(uuid())
    auth_id            String                   @unique
    firstname          String
    lastname           String
    data               Json
    activationToken    String?                  @default(uuid())
    createdAt          DateTime                 @default(now())
    updatedAt          DateTime                 @updatedAt
    following          User[]                   @relation("Follow")
    followers          User[]                   @relation("Follow")
    exoskeletons       ExoskeletonAttribution[]
    challenges         Challenge[]
    authoredChallenges Challenge[]              @relation(name: "challengeAuthor")
    surveys            Survey[]
    preferences        Preferences?
}

model Preferences {
    id        String       @id @default(uuid())
    userId    String       @unique
    user      User         @relation(fields: [userId], references: [id])
    weekStart WeekStartDay @default(MONDAY)
    darkMode  Boolean      @default(false)
    unitType  UnitType     @default(METRIC)
    createdAt DateTime     @default(now())
    updatedAt DateTime     @updatedAt
}

model User {
    id                 String                   @id @default(uuid())
    auth_id            String                   @unique
    firstname          String
    lastname           String
    data               Json
    activationToken    String?                  @default(uuid())
    createdAt          DateTime                 @default(now())
    updatedAt          DateTime                 @updatedAt
    following          User[]                   @relation("Follow")
    followers          User[]                   @relation("Follow")
    exoskeletons       ExoskeletonAttribution[]
    challenges         Challenge[]
    authoredChallenges Challenge[]              @relation(name: "challengeAuthor")
    surveys            Survey[]
    preferences        Preferences?
}

model Preferences {
    id        String       @id @default(uuid())
    userId    String       @unique
    user      User         @relation(fields: [userId], references: [id])
    weekStart WeekStartDay @default(MONDAY)
    darkMode  Boolean      @default(false)
    unitType  UnitType     @default(METRIC)
    createdAt DateTime     @default(now())
    updatedAt DateTime     @updatedAt
}

I made this interface:

import { Preferences, User } from "@prisma/client"

export interface UserWithRoles extends User {
    roles: string[]
}

import { Preferences, User } from "@prisma/client"

export interface UserWithRoles extends User {
    roles: string[]
}

And I have a function that find a user, aggregate it in a new object with roles array, and the output of this function seems to drop the preferences relation, even if I explicitly include it in my findUnique function. Not an expert in typescript yet, so I may miss something basic, but it should works from what I understand. Need a lil help on that one please, Thanks !

Extends result relations

Hi, I have 3 different objects:

model User {
    id           String                   @id @default(uuid())
    auth_id      String                   @unique
    firstname    String
    lastname     String
    createdAt    DateTime                 @default(now())
    updatedAt    DateTime                 @updatedAt
    sessions     Session[]
    challenges   Challenge[]
    exoskeletons ExoskeletonAttribution[]
}

model Exoskeleton {
    id           String                   @id @default(uuid())
    serial       String
    createdAt    DateTime                 @default(now())
    updatedAt    DateTime                 @updatedAt
    sessions     Session[]
    attributions ExoskeletonAttribution[]
}

model ExoskeletonAttribution {
    id            String      @id @default(uuid())
    exoskeletonId String
    userId        String
    createdAt     DateTime    @default(now())
    revokedAt     DateTime?
    exoskeleton   Exoskeleton @relation(fields: [exoskeletonId], references: [id])
    user          User        @relation(fields: [userId], references: [id])
}

model User {
    id           String                   @id @default(uuid())
    auth_id      String                   @unique
    firstname    String
    lastname     String
    createdAt    DateTime                 @default(now())
    updatedAt    DateTime                 @updatedAt
    sessions     Session[]
    challenges   Challenge[]
    exoskeletons ExoskeletonAttribution[]
}

model Exoskeleton {
    id           String                   @id @default(uuid())
    serial       String
    createdAt    DateTime                 @default(now())
    updatedAt    DateTime                 @updatedAt
    sessions     Session[]
    attributions ExoskeletonAttribution[]
}

model ExoskeletonAttribution {
    id            String      @id @default(uuid())
    exoskeletonId String
    userId        String
    createdAt     DateTime    @default(now())
    revokedAt     DateTime?
    exoskeleton   Exoskeleton @relation(fields: [exoskeletonId], references: [id])
    user          User        @relation(fields: [userId], references: [id])
}

The last one have a manyToOne relation for both User & Exoskeleton. My goal is to add a custom field to User, named currentExoskeleton, based on the relation to exoskeletonAttribution (i take the last in date), to fetch to associated Exoskeleton. So i started to wrote this:

result: {
  user: {
    currentExoskeleton: {
      needs: {
        exoskeletonAttribution: true,
      },
      compute(user) {
          // nothing here for the moment
      }
    },
  },
},

result: {
  user: {
    currentExoskeleton: {
      needs: {
        exoskeletonAttribution: true,
      },
      compute(user) {
          // nothing here for the moment
      }
    },
  },
},

But typescript already crying on me on the needs part, "impossible to align type boolean to never". And i would also like to know if it's possible to user async/await on compute ? (if yes, how ? should i return an async function from the compute function ?) Thanks 😉
