如何删除TypeORM和Nest.js中的嵌套实体

@OneToOne(() => Profile, profile => profile.user, { cascade: true })
@JoinColumn()
profile: Profile;

import { Injectable } from '@nestjs/common';
import { InjectRepository } from '@nestjs/typeorm';
import { Repository } from 'typeorm';
import { User } from './user.entity';

@Injectable()
export class UserService {
  constructor(
    @InjectRepository(User)
    private userRepository: Repository<User>,
  ) {}

  // 其他方法...
}

async deleteNestedEntity(userId: number): Promise<void> {
  const user = await this.userRepository.findOne(userId, { relations: ['profile'] });
  if (user) {
    await this.userRepository.remove(user);
  }
}

import { Controller, Delete, Param } from '@nestjs/common';
import { UserService } from './user.service';

@Controller('users')
export class UserController {
  constructor(private readonly userService: UserService) {}

  @Delete(':id')
  async deleteUser(@Param('id') id: string): Promise<void> {
    await this.userService.deleteNestedEntity(parseInt(id, 10));
  }
}
