Prisma upsert提供的许多问题列表&lt；Json&>，预期为SimilarCreateWithoutMovieInput

问题描述

使用"@prisma/client": "^2.25.0"

 on prisma.upsertOneMovie. Provided List<Json>, expected SimilarCreateWithoutMovieInput or SimilarCreateWithoutMovieInput or SimilarUncheckedCreateWithoutMovieInput or SimilarUncheckedCreateWithoutMovieInput:
[0] type SimilarCreateWithoutMovieInput {
[0]   id: Int
[0]   backdrop_path: String
[0]   title: String
[0]   name: String
[0]   release_date: DateTime
[0]   overview: String
[0]   show: TVShowCreateNestedOneWithoutSimilarInput
[0] }

代码

const { PrismaClient } = require('@prisma/client')
const prisma = new PrismaClient()
...
        let result = await apiRequest
        let similar = result.similar.results.map(similar_movie => {
          return {
            id: similar_movie.id,
            backdrop_path: similar_movie.backdrop_path,
            title: similar_movie.title,
            name: similar_movie.name,
            release_date: similar_movie.release_date,
            overview: similar_movie.overview,
            movieId: result.id
          }
        })

        const movie = {
        id: result.id,
...
        similar: {
            upsert: similar
          }
        }
        const upsertMovie = await prisma.movie.upsert({
          where: { id: movie.id },
          update: movie,
          create: movie,
        })

这里是schema.prisma

model Movie {
  id                    Int         @id
...other fields and attributes...
similar             Similar[]
}

model Similar {
    id              Int         @id @default(autoincrement())
    tmdb_id         Int         @unique
    backdrop_path   String
    title           String?
    name            String?
    release_date    String
    overview        String
    movie           Movie?      @relation(fields: [movie_id], references: [id])
    show            TVShow?         @relation(fields: [show_id], references: [id])
    movie_id    Int?
    show_id Int?
}

Similar应为其他Movies嵌套在特定Movie对象中的数组[]，本身不能

我没有在生成的类型上使用Prisma upsert的经验，我收到了上面的错误。我希望插入一个Movie，同时插入与Movie相关的多个Similar记录。

我已尝试使用connectOrCreate，但它不支持在按预期创建movie的一条记录时创建多条similar记录
我如何实现这一点？

推荐答案

问题是PRISMAcreateMany在SQLite上不可用，而在PostgreSQL连接器上可用。

const movie = {
        ...result,
        similar: {
          connectOrCreate: result.similar.map(s => ({
            create: s,
            where: { id: s.id },
          }))
        }
      }

const upsertMovie = await prisma.movie.upsert({
          where: { id: movie.id },
          update: movie,
          create: movie,
        })
