TypeOrm OneToOne 关系导致不需要的列嵌入

【问题描述】：

我有 2 个实体具有 OneToOne 关系（用户和 CodUser），并且用户具有 JoinColumn。当 TypeOrm 将此模式同步到数据库时，它会在用户中创建 CodUser 列，因此它嵌入 CodUser 并为 CodUser 实体创建一个单独的表。

我想要的是 2 个实体是分开的，并且 CodUser 中的列仅出现在我的（Postgres）数据库的 CodUser 表中。 我相信这正是 TypeOrm 对demonstrate OneToOne 关系使用的模式，但似乎有些不对劲。

user.entity.ts

@Entity()
export class User 
@PrimaryGeneratedColumn()
id: number;

@Column( unique: true )
email: string;

@Column( nullable: true )
avatar: string;

@Column()
password: string;

@Column(
    type: "text",
    array: true,
    nullable: false,
    default: `$Role.Player`
)
roles: Role[];

@OneToOne((type) => CodUser, 
    cascade: true
)
@JoinColumn()
codUser: CodUser;

@Column( default: 0 )
invalidLoginAttempts: number;

@Column( nullable: true )
activationCode: string;

@Column( nullable: false, default: false )
active: boolean;

@Column( nullable: true )
lockedUntil: Date;

@Column( nullable: true )
lastLoginAttemptAt: Date;

@OneToMany((type) => ChallangeUser, (challangeUser) => challangeUser.user)
challanges: ChallangeUser[];

@CreateDateColumn( type: "timestamp" )
createdAt: Date;

@UpdateDateColumn( type: "timestamp" )
updatedAt: Date;

constructor(email: string, username: string, platform: Platform, password: string) 
    this.email = email;
    this.codUser = new CodUser(username, platform);
    this.password = password;

cod-user.entity.ts

@Entity()
export class CodUser 
@PrimaryGeneratedColumn()
id: string;

@Column( unique: true )
username: string;

@Column( nullable: false )
platform: Platform;

@Column( type: "jsonb", nullable: true )
recentWarzoneMatches: object[];

@Column( nullable: true )
recentWarzoneMatchesSyncedAt: Date;

constructor(username: string, platform: Platform) 
    this.username = username;
    this.platform = platform;

结果：

同步交易：

删除我的 NestJS 项目中的 /dist 文件夹解决了这个问题，这似乎毕竟是一个 NestJS 问题。
