Prisma作为参数

Question

我正在从TypeORM过渡到Prisma。

TypeORM

const user = await getUser("123", ["car", "car.wheels"])
static async getUser(
    userId: string,
    relations: string[]
  ) {
  return await UserEntity.findOne(
    {
      where: {
               id: userId
             },
      relations: relations
    }
  )
}

在Prisma中，它使用include获取表关系。如何将变量关系传递给Primsa函数？

Answer 1

目前我们是这样做的，您需要将您的关系string[]映射到字典结构

 // define your variable with default includes
    const userInclusion = <Prisma.UserEntityInclude >{ include1: false, include2: false };
    // map from your string relations to dictionary 
    relations?.forEach(value =>{
     userInclusion[value as keyof typeof userInclusion] = true;
    })
  let args: Prisma.UserEntityFindUniqueArgs = { where: { id: userId } };
  if (relations.length > 0) {
            args = {
                ...args,
                include: userInclusion
            };
        }
     }
  const user = await UserEntity.findOne(args);
