Когда я пытаюсь обновить строку в таблице с отношением @ManytoONe, у меня возникает ошибка.

Я хочу обновить строку в EntrainementCalendar, которая имеет @ManytoONe с Entrainements

Я пытался: - использовать каскад: true в отношении, но с @Put я получаю ошибку, - использовать каскад: true с @POST itобновить строку в таблице EntrainementCalendar, но создать новую в Entrainements

Первая сущность 

@Entity()

export class EntrainementCalendar extends HistoriqueEntity {
    @Column()
    start: Date;
    @Column({nullable: true})
    end: Date;
    @Column()
    title: string;

    @ManyToOne( type => Entrainements, training => training.id, {persistence: false, onDelete: 'CASCADE', onUpdate: 'NO ACTION'})
    @JoinTable()
    training: Entrainements;

    @Column()
    draggable: boolean;
}

Вторая сущность 



    @Entity()
       export class Entrainements extends HistoriqueEntity {
        @Column()
        title: string;

        @ManyToMany( () => Categories )
        @JoinTable()
        category: Categories[];

        @Column()
        distance: string;

        @Column({nullable: true})
        strokesStart: number;

        @Column({nullable: true})
        comments: string;

        @Column()
        warmUp: string;

        @Column({nullable: true})
        cadence: string;

        @ManyToOne(type => Season, season => season.name)
        season: Season;

        @Column()
        rest: string;

        @ManyToOne(type => Color, color => color.primary, {cascade: true})
        color: Color;

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

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

        @Column({nullable: true})
        draggable: boolean;

        @ManyToOne(type => Roles, role => role.entrainements)
        role: Roles;

        @ManyToMany( () => Exercices )
        @JoinTable()
        exercices: Exercices[];
    }


    ```

    I would like the row `EntrainementCalendar` without creating a new one in `Entrainements`
