Typeorm更新实体/表

Question

这是我的用户实体：

@PrimaryGeneratedColumn()
userId: number;

@Column({type:"varchar", length:"300"})
userName: string;

@OneToOne(type => UserProfile, {cascadeAll:true})
@JoinColumn()
userProfile: UserProfile;

@OneToOne(type => UserCredential, {cascadeAll:true, eager:true})
@JoinColumn()
userCredential: UserCredential;

@OneToOne(type => BusinessUnit, {cascadeAll:true})
@JoinColumn()
businessUnit: BusinessUnit;

@ManyToMany(type => ProductCategory)
@JoinTable()
productCategory: ProductCategory[];

这是我要更新的新数据：

User {
  userName: 'qweret@gmail.com',
  userProfile: 
   UserProfile {
     firstName: 'dcds',
     lastName: 'Faiz',
     mobile: '42423423',
     addressLine1: 'Delhi',
     addressLine2: 'Delhi',
     city: '-',
     country: '-',
     zipCode: '234243',
     homeTelephone: '-',
     dayOfBirth: 0,
     monthOfBirth: 0,
     yearOfBirth: 0 },
  userCredential: UserCredential { credential: 'abcd@123' } }

我正在通过其userId搜索用户。

return await getManager()
               .createQueryBuilder(User, "user")
               .where("user.userId = :id", {id})
               .getOne();

上面的查询给了我结果：

User {
  createdDate: 2018-03-29T06:45:16.322Z,
  updatedDate: 2018-04-01T06:28:24.171Z,
  userId: 1,
  userName: 'qweret@gmail.com' }

我想更新我的用户表及其相关表

manager.save(user)

将在表格中插入新行，而不是更新现有行。有没有一种方法可以更新整个用户表及其相关表，而无需手动更新每一列？我不想执行这样的任务：

let user = await userRepositiory.findOneById(1);
user.userName = "Me, my friends and polar bears";
await userRepository.save(user);

let userProfile = await userProfileRepository.findOneById(1);
 userProfile.firstName = "";
 userProfile.lastName = "";
    ....// etc
 await userRepository.save(userProfile);

 // and so on update other tables.

试试这个方法：

await this. userRepository.update(
                user.id ,
                user
              );

const updatedUser = await this.repository.findOne(user.id);
