Node.js 更新请求多个NestJS

我对编码非常陌生，我正在使用nestjs和PostegreSql一起创建一个应用程序 每当我尝试更新某些内容时，都会出现错误

我有与

@manytomy

关系的实体，如果我删除这些关系，更新将正常工作。 但是如果我让

@manytomy

关系运行，它将不起作用

错误消息：

[Nest] 46879   - 09/21/2019, 7:38 PM   [ExceptionsHandler] column "entrainementsId" of relation "entrainements" does not exist +639401ms

行使实体：

@Entity()
export class Exercices extends HistoriqueEntity {
    @Column()
    name: string;

    @Column()
    description: string;

    @ManyToOne(type => TypeExercices, typeExercices => typeExercices.exercices)
    typeExercices: TypeExercices;

    @ManyToMany(type => Entrainements, entrainements => entrainements.exercices)
    entrainements: Entrainements[];
}

分类实体

@Entity()
export class Categories extends HistoriqueEntity {
    @Column()
    name: string;

    @ManyToMany(type => Entrainements, entrainements => entrainements.category)
    entrainements: Entrainements[];

}

夹带控制员

    @Put(':id/update')
    async update(@Param('id') id, @Body() entrainementsData: Entrainements): Promise<UpdateResult> {
        entrainementsData.id = Number(id);
        return this.service.updateTraining(entrainementsData);
    }

@Put（':id/update'）
异步更新（@Param（'id'）id，@Body（）entrainementsData:Entrainements）：承诺{
entrainementsData.id=编号（id）；
返回此.service.updateTraining（entrainementsData）；
}

夹带服务

   async updateTraining(entrainement: Entrainements): Promise<UpdateResult> {
        return await this.entrainementsRepository.update(entrainement.id, entrainement);
    }

异步更新培训（夹带：夹带）：承诺{
返回等待此.entrainementsRepository.update（entrainement.id，entrainement）；
}

您应该定义相反的绑定：

@ManyToMany( () => Exercices, (exercices) => exercices.entrainements, {cascade: true} )
@JoinTable()
exercices: Exercices[];

@ManyToMany( () => Exercices, (exercices) => exercices.entrainements, {cascade: true} )
@JoinTable()
exercices: Exercices[];
