mysql - 类型ORM。无法执行更新查询，因为未定义更新值。调用\"qb.set(...)\"方法指定更新值

Question

我正在使用 MySQL DB、TypeORM 和 ExpressJS。

我有 2 个实体:用户和客户端。它们之间存在一对一的关系。客户端有外键。

保存客户端时出现以下错误:

Cannot perform update query because update values are not defined. Call "qb.set(...)" method to specify updated values

用户实体:

export class User extends BaseEntity {
  @PrimaryGeneratedColumn()
  id: number

  @Column()
  role: string

  @Column()
  email: string

  @Column()
  password: string

  @Column({ default: '' })
  avatar: string

  @Column()
  firstName: string

  @Column()
  lastName: string

  @Column()
  fullName: string

  @Column({ default: '' })
  phone: string

  @Column({ type: 'text', nullable: true })
  description: string

  @Column({ nullable: true })
  age: number

  @OneToOne(_type => Freelancer, freelancer => freelancer.user, { nullable: true })
  freelancer: Freelancer

  @OneToOne(_type => Client, client => client.user, { nullable: true })
  client: Client
}

客户端实体:

@Entity()
export class Client extends BaseEntity {
  @PrimaryGeneratedColumn()
  id: number

  @Column()
  companyName: string

  @ManyToOne(_type => Position, position => position.clients)
  position: Position

  @OneToOne(_type => ClientReview, clientReview => clientReview.client, { nullable: true })
  @JoinColumn()
  review: ClientReview

  @OneToMany(_type => Project, project => project.client, { nullable: true })
  projects: Project[]

  @OneToOne(_type => User, user => user.client)
  @JoinColumn()
  user: User
}

auth.service 中的代码概述，我在其中保存 client:

const user = userRepository.create({
      email,
      password: hashedPassword,
      role,
      description,
      firstName,
      lastName,
      fullName: `${firstName} ${lastName}`,
      phone
    })

      const clientRepository = getRepository(Client)
      const positionRepository = getRepository(Position)

      const positionEntity = await positionRepository.findOne({ id: position.id })

      const client = clientRepository.create({
        companyName,
        position: positionEntity,
        user
      })

      await userRepository.save(user)
      await clientRepository.save(client)

当我从实体客户端中删除列user时，客户端和用户将被保存，但分开保存，它们之间没有关系。但我想要他们之间建立关系。

我做错了什么？

我该如何解决这个问题？

就我而言，我忘记在 @OneToOne 关系中添加 @JoinColumn。
