У меня есть 2 объекта, которые имеют отношение OneToOne (User и CodUser), а у User есть JoinColumn. Когда TypeOrm синхронизирует этот шаблон с базой данных, он создает столбцы CodUser внутри пользователя, поэтому он встраивает CodUser И создает отдельную таблицу для объекта CodUser.
Я хочу, чтобы 2 объекта были отдельными, а столбцы в CodUser появляются только в таблице CodUser в моей (Postgres) базе данных. Я считаю, что это точный шаблон, используемый TypeOrm для демонстрации отношений OneToOne, но, похоже, что-то не так.
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()

@Column({ unique: true })

@Column({ nullable: false })

@Column({ type: "jsonb", nullable: true })
