Postgresql Postgres键（keyId，keyId，keyId）=（2，2，2）不存在于表约束中

当我开始为我的数据库添加种子时，一切都很好，但当我尝试将第二批优惠添加到同一用户的第二个列表时，第一批优惠成功添加到第一个用户列表

/实体/用户.ts

/entity/Listing.ts User=>1:M=>Listing

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

  @Column({ type: 'varchar', length: 255 })
  title: string

  @OneToMany(() => Offer, offer => offer.listing)
  offers: Offer[]

  @PrimaryColumn()
  userId: number

  @ManyToOne(() => User, user => user.listings)
  @JoinColumn({ name: 'userId' })
  user: Promise<User>
}

错误消息：

query failed: INSERT INTO "offer"("price", "wage", "hoursOfWeek", "housing", "tips", "overtimes", "notes", "offerTypeId", "positionId", "listingId") VALUES ($1, $2, $3, $4, $5, $6, $7, $8, $9, $10) RETURNING "id", "housing", "tips", "overtimes" -- PARAMETERS: [256,16,32,true,true,true,"Qui dolores assumenda doloremque doloribus.",1,2,2]
error: { error: insert or update on table "offer" violates foreign key constraint "FK_d33dccabb2f699c92920ff197c8"
detail: 'Key (listingId, listingId, listingId)=(2, 2, 2) is not present in table "listing".',

这是错误的

你应该这样做

 await Promise.all(users.map(user => User.create(user).save()))

我发现我的代码有什么问题，我使用PrimaryColumn处理1:M关系，但我只需要一个列

谢谢，我用上面的代码到处替换它，但仍然是一样的错误，第一个列表的一堆报价是可以的，但是第二个包失败了。我放置了setTimer，转到postgres，它显示我的2个清单都是用1和2个IDE创建的。然后时间到了，第二次上市的报价再次失败。
