Question

我有

@Entity('procedures')
export class ProcedureEntity {

    @PrimaryGeneratedColumn()
    id: number;

    @OneToMany(type => MediaFileEntity, media => media.procedure, {
        cascade: true
    })
    files: MediaFileEntity[];

};

和

@Entity('media_files')
export class MediaFileEntity {

    @PrimaryGeneratedColumn()
    id: number;

    @Column({ nullable: true })
    deletedAt: Date;

    @ManyToOne(type => ProcedureEntity, procedure => procedure.files)
    procedure: ProcedureEntity;

};

有人知道我如何创建查询生成器，以便获得所有过程，但媒体文件具有deletedAt NULL吗？

我正在尝试

const procedures = await this.procedureRepository
    .createQueryBuilder("procedure")
    .leftJoinAndSelect("procedure.doctor", "doctor")
    .leftJoinAndSelect("procedure.patient", "patient")
    .innerJoin('procedure.files', 'mediaFile', 'mediaFile.deletedAt IS NULL')
    .where("(patient.id = :id OR doctor.id = :doctorId)", { id: user.id, doctorId: user.id })
    .andWhere('procedure.deletedAt IS NULL')
    .getMany();

但是我得到Cannot find name 'where'。这很奇怪，因为this.procedureRepository .createQueryBuilder("procedure")也是SelectQueryBuilder<ProcedureEntity>，this.procedureRepository .createQueryBuilder("procedure") .leftJoinAndSelect("procedure.doctor", "doctor") .leftJoinAndSelect("procedure.patient", "patient") .innerJoin('procedure.files', 'mediaFile', 'mediaFile.deletedAt IS NULL');

谢谢！

您遇到语法错误。 innerJoin之后是分号。这是错误的原因吗？
