我有 3 张桌子

  1. 出席
  2. 用户
  3. 出勤验证。

出勤->多对一->用户

出勤->OneToOne->出勤验证

现在我想查询特定用户的出勤率，并希望在出勤对象中嵌入完整的用户和出勤验证数据并将其返回。这是我尝试过的，但它给了我错误Invalid syntax near where。

我努力了

 const listOfAttendance = await this.attendanceRepository.find({
      where: {
        punchInDateTime: Between(dateFrom, dateTo),
      },
      order: {
        id: 'ASC',
      },
      join: {
        alias: 'attendance',
        leftJoinAndSelect: {
          user: 'attendance.user',
          outlet: 'attendance.outlet',
          punchAck: 'attendance.punchAck',
          verification: 'attendance.attendanceVerification',
        },
      },
    })

查询被 TypeORM 解析

出勤实体（排除了一些字段以使代码干净）

import { ApiPropertyOptional } from '@nestjs/swagger'
import {
  BaseEntity,
  Column,
  Entity,
  ManyToOne,
  OneToMany,
  OneToOne,
  PrimaryGeneratedColumn,
} from 'typeorm'
import { AttendanceVerification } from '@modules/attendance/attendance-verification/attendance_verification.entity'
import { Break } from '@modules/attendance/break/break.entity'
import { PunchAck } from '@modules/attendance/punch-ack/punch_ack.entity'
import { Outlet } from '@modules/outlet/outlet.entity'
import { User } from '@modules/users/users.entity'

@Entity('attendance')
export class Attendance extends BaseEntity {
  @ApiPropertyOptional()
  @PrimaryGeneratedColumn()
  id: number

  @ApiPropertyOptional()
  @Column()
  punchInImage: string

  @ApiPropertyOptional()
  @Column({ type: 'timestamp' })
  punchInDateTime: Date

  @ApiPropertyOptional()
  @Column()
  approvalStatus: string

  @ApiPropertyOptional()
  @Column()
  userId: number

  @ApiPropertyOptional()
  @Column()
  outletId: number

  @ManyToOne(type => User, user => user.attendance)
  user: User

  @OneToOne(type => Outlet, outlet => outlet.attendance)
  outlet: Outlet

  @OneToMany(type => Break, breaks => breaks.attendance)
  breaks: Break[]

  @OneToMany(type => PunchAck, punchAck => punchAck.attendance)
  punchAck: PunchAck[]

  @OneToOne(
    type => AttendanceVerification,
    attendanceVerification => attendanceVerification.attendance
  )
  attendanceVerification: AttendanceVerification
}

我在互联网上找到的所有解决方案都使用 queryBuilder。我不想使用那种冗长的方法。

来自 typeorm 文档：https ://typeorm.io/#/find-options 您可以使用以下内容：

userRepository.find({
    join: {
        alias: "user",
        leftJoinAndSelect: {
            profile: "user.profile",
            photo: "user.photos",
            video: "user.videos"
        }
    }
});

或者您的示例可能如下所示：

const returnedResult = await this.attendanceRepository.findOne({
      where: { userId: id, status: 'PUNCHED IN' },
      join: {
         alias: "attendance",
         leftJoinAndSelect: {
            user: "attendance.user",
            outlet: "attendance.outlet",
        }
      },
    });

根据我的个人经验，如果您需要编写复杂的查询，则必须使用 QueryBuilder。乍一看，它看起来很尴尬。
