Prisma -如何将项目推入外部对象列表

Question

我使用mongodb v5.0.13

//schema.prisma
model Video {
id          Int    @id @map("_id")
title       String
description String
tags        Tag[]
}
model Tag {
id          String  @id @map("_id")
video       Video?  @relation(fields: [videoId], references: [id])
videoId     Int?
}

我希望能够为视频记录添加标签。

//index.ts
await prisma.video.create({
data: {
id: 1,
description: "",
title: "Dancing Cats",
},
});
let tag = {id: "funny"};
await prisma.tag.create({
data: tag,
});
await prisma.video.update({
where: {
id: 1,
},
data: {
tags: {
push: tag,
},
},
});

我得到这个错误每当我运行update:

error TS2322: Type '{ push: Tag | null; }' is not assignable to type 'TagUncheckedUpdateManyWithoutVideoNestedInput | TagUpdateManyWithoutVideoNestedInput | undefined'.
Object literal may only specify known properties, and 'push' does not exist in type 'TagUncheckedUpdateManyWithoutVideoNestedInput | TagUpdateManyWithoutVideoNestedInput'.
38         push: tag,
~~~~~~~~~

使用mongodb驱动程序的代码没有太大不同(语法方面)，它可以工作。

你有没有试过:

await prisma.video.create({
data: {
id: 1,
description: "",
title: "Dancing Cats",
},
});
let tag = {id: "funny"};
const newTag = await prisma.tag.create({
data: tag,
});
await prisma.video.update({
where: {
id: 1,
},
data: {
tags: {
push: newTag,
},
},
});
