Crud: Nested entity creation

[chatoooo]

I got two entities with relation like this

@Entity()
export class Parent extends BaseEntity {

  @IsEmpty({groups: [CrudValidationGroups.CREATE]})
  @ApiProperty()
  @PrimaryGeneratedColumn()
  public id: number;

  @ApiProperty()
  @IsString({always: true})
  @Column({nullable: false})
  public name: string;

  @ApiProperty({type: () => [Child]})
  @OneToMany(() => Child, child => child.parent)
  public children: Child[];
}

@Entity()
export class Child extends BaseEntity {

  @IsEmpty({groups: [CrudValidationGroups.CREATE]})
  @ApiProperty()
  @PrimaryGeneratedColumn()
  public id: number;

  @ApiProperty()
  @Column()
  public name: string;

  @ApiProperty({type: () => Parent})
  @ManyToOne(() => Parent, parent => parent.children, {onDelete: "SET NULL"})
  public parent: Parent;

  @Column()
  public parentId: number;

with /parent controller

@Crud({
    model: {type: Parent},
    routes: {exclude: ["replaceOneBase", "createManyBase"]},
    query: {
        alwaysPaginate: true,
        join: {
            children: {
                eager: true,
            },
        },
    },
})
export class ParentsController {}

When I try to create both Parent and Child in one POST call to ParentsController, only Parent is created.

POST /parents

{
  "name": "Peter sr.",
  "children": [{
    "name": "Peter jr."
  }]
}

{
  "id": 1,
  "name": "Peter sr.",
  "children": []
}

But when Child is created beforehand and id is provided, it assigns Child to the Parent.

POST /parents

{
  "name": "Peter sr.",
  "children": [{
    "id": 1
  }]
}

{
  "id": 1,
  "name": "Peter sr.",
  "children": [{
    "id": 1,
    "name": "Peter jr.",
    "parentId": 1,
  }]
}

Is there any trick that allows me to use the first scenario with result of the second? I can @Override createOne and deal with children array seperately. But it would be nice if this can be handled by CRUD.

I hate when I find solution right after I asked online. It's more related to TypeORM. { cascade: true } on Parent.children relation does the trick.
