我正在使用TypeORM设置数据库表。我有一个User实体和一个MediaList实体。User与MediaList实体具有一对多关系，如下所示：

@Entity('users')
export class User extends BaseEntity {
  @PrimaryGeneratedColumn('uuid') public id: string;

  @Column('varchar', {length: 50, name: 'first_name'})
  public firstName: string;

  @Column('varchar', {length: 50, name: 'last_name'})
  public lastName: string;

  @Column('varchar', {nullable: false, length: 255})
  public email: string;
  .
  .
  .
  @OneToMany((type) => MediaList, (mediaList) => mediaList.owner)
  public mediaLists: MediaList[];
}

@Entity('media_list')
export class MediaList extends BaseEntity {

  @PrimaryGeneratedColumn('uuid') public id: string;

  @Column('varchar', {length: 50})
  public title: string;

  @ManyToOne((type) => User, (user) => user.mediaLists)
  public owner: User;
}

我创建了一个用户，如下所示：

const user = User.create({
        firstName: 'john',
        lastName: 'doe',
        email,
        password,
        permissions: generalPermissions,
    });

    await user.save();

当我保存用户时，我得到一个引用错误：

(node:16708) UnhandledPromiseRejectionWarning: ReferenceError: MediaList is not defined

我做错了什么？Map不正确吗？
