Bug description

Nested write query fails for a 1-n relation – migration from mongoose

How to reproduce

Clone repo
Install dependencies
Create docker-compose.yml:
Run docker-compose up -d
Seed database

git clone git@github.com:prisma/migrate-from-mongoose-to-prisma.git
cd migrate-from-mongoose-to-prisma
npm install
touch docker-compose.yml
touch .env

docker-compose.yml file

version: '3'
services:
  mongodb:
   image: 'prismagraphql/mongo-single-replica:4.4.3-bionic'
   environment: 
      MONGO_INITDB_ROOT_USERNAME: root
      MONGO_INITDB_ROOT_PASSWORD: prisma
   ports:
    - 27017:27017

Set env variable:

DATABASE_URL="mongodb://root:prisma@localhost:27017/prisma-mongo?authSource=admin&retryWrites=true&w=majority"

Start up db:

docker-compose up -d

Seed database

npm run seed

Install Prisma and Prisma Client:

npm i -D prisma && npm i @prisma/client

Initialize Prisma

npx prisma init --datasource-provider mongodb

Introspect db:

npx prisma db pull

Original schema:

type UsersProfile {
  bio String
}

model categories {
  id   String @id @default(auto()) @map("_id") @db.ObjectId
  v    Int    @map("__v")
  name String
}

model posts {
  id         String   @id @default(auto()) @map("_id") @db.ObjectId
  v          Int      @map("__v")
  author     String   @db.ObjectId
  categories String[] @db.ObjectId
  content    String
  published  Boolean
  title      String
}

model users {
  id      String        @id @default(auto()) @map("_id") @db.ObjectId
  v       Int           @map("__v")
  email   String        @unique(map: "email_1")
  name    String
  profile UsersProfile?
}

Update relations:

// schema.prisma

type UsersProfile {
  bio String
}

model Category {
  id      String   @id @default(auto()) @map("_id") @db.ObjectId
  v       Int      @default(0) @map("__v") @ignore
  name    String
  posts   Post[]   @relation(fields: [postIds], references: [id])
  postIds String[] @db.ObjectId

  @@map("categories")
}

model Post {
  id        String  @id @default(auto()) @map("_id") @db.ObjectId
  title     String
  content   String
  published Boolean @default(false)
  v         Int     @default(0) @map("__v") @ignore

  author   User   @relation(fields: [authorId], references: [id])
  authorId String @map("author") @db.ObjectId

  categories  Category[] @relation(fields: [categoryIds], references: [id])
  categoryIds String[]   @map("categories") @db.ObjectId

  @@map("posts")
}

model User {
  id      String        @id @default(auto()) @map("_id") @db.ObjectId
  v       Int           @default(0) @map("__v") @ignore
  email   String        @unique(map: "email_1")
  name    String
  profile UsersProfile?
  posts   Post[]

  @@map("users")
}

Push schema

npx prisma db push

Update nested write in src/controller/post.js

const { PrismaClient } = require('@prisma/client')
const prisma = new PrismaClient()

const createDraft = async (req, res) => {
  const { title, content, authorEmail } = req.body

  try {
    const draft = await prisma.post.create({
      data: {
        title,
        content,
        author: {
          connect: {
            email: authorEmail
          }
        },
      }
    })

    res.status(201).json(draft)
  } catch (error) {
    return res.status(500).json({ error })
  }
}

Start server:

RUST_BACKTRACE=1 RUST_BACKTRACE=full npm run dev

Make a request to the route:

curl -X POST http://localhost:3000/post -H 'Content-Type: application/json' -d '{ "title": "Request", "content": "no funny business", "authorEmail":"nikolas@prisma.io"}'

I’ve also encountered this issue. The error only appears when writing to the table.

  company                     Company? @relation(fields: [companyId], references: [id])
  companyId                   String @db.ObjectId @map("company")  // <--- mapping to "company" with the same name as the relation

Changing one or the other works:

  // Rename company to companyObject
  companyObject               Company? @relation(fields: [companyId], references: [id])
  companyId                   String @db.ObjectId @map("company")
