mysql where 子句中的列“id”不明確

Question

我是 mysql 和 typeorm 的新手，我正在嘗試獲取屬於特定用戶的所有帖子，我想使用 id 進行此操作，但Column 'id' in where clause is ambiguous 。

這是我的服務

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

@Injectable()
export class UserService {
  constructor(
    @InjectRepository(User)
    private readonly userRepository: Repository<User>,
  ) {}
 
  async userPosts(id): Promise<User> {
    return this.userRepository
      .createQueryBuilder('user')
      .leftJoinAndSelect('user.posts', 'post')
      .where('user.id = :id', { id: id }) // whats the problem here ?
      .getOne();
  }
 
}

那就是我的用戶實體

import { Post } from 'src/post/post.entity';
import { Entity, Column, PrimaryGeneratedColumn, OneToMany } from 'typeorm';

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

  @Column()
  firstName: string;

  @Column()
  lastName: string;

  @Column({ default: true })
  isActive: boolean;

  @OneToMany(() => Post, (post: Post) => post.user, {
    onDelete: 'CASCADE',
    onUpdate: 'CASCADE',
  })
  posts: Post[];
}

Answer 1

{ id: id } 您沒有指定 id 字段來自哪個表。 您的意思是：{ user.id: id }
