Issue with delete Entity that has ManyToMany relation

I have been banging my head against a wall this evening, and I can’t tell if I have done something wrong here. Standard entity, very simple for the most part. Postgres is the database.

@Entity('group')
export class Group {
  @PrimaryGeneratedColumn({ name: 'id' })
  id: number;

  @Column({ name: 'name' })
  name: string;

  @Column({ name: 'owner_id' })
  ownerId: number;

  @Column({ name: 'created_by_id' })
  createdById: number;

  @ManyToOne(() => User)
  @JoinColumn({ name: 'owner_id', referencedColumnName: 'id' })
  owner: User;

  @ManyToOne(() => User)
  @JoinColumn({ name: 'created_by_id', referencedColumnName: 'id' })
  createdBy: User;

  @ManyToMany(() => Package, {
    onDelete: 'CASCADE'
  })
  @JoinTable({
    name: 'package_group_xref',
    joinColumn: { name: 'group_id' },
    inverseJoinColumn: { name: 'package_id' }
  })
  packages: Package[];

  @ManyToMany(() => Document)
  @JoinTable({
    name: 'document_group_xref',
    joinColumn: { name: 'group_id' },
    inverseJoinColumn: { name: 'document_id' }
  })
  documents: Document[];
}

@Crud({ model: { type: Group } })
@ApiTags('groups')
@ApiBearerAuth()
@Controller('groups')
export class GroupController extends CrudControllerBase<Group> {
  constructor(readonly service: GroupService) {
    super(service);
  }
}

A query is being generated that has identifiers in it that aren’t quoted. I am not even sure where group_documents_rid is coming from–I assume it is a name generated by typeorm, maybe?

I have tried the delete on both sides of the relation, and I just get the inverse of the same error. One is document_groups_rid, and this one, group_documents_rid.

@zMotivat0r Could you triage this issue and let me know if you think it is a nestjsx/crud or TypeORM issue?

Also, if you have an idea about what needs to be done, please let me know and I can try and make the changes if you don’t have the time.

@zMotivat0r There has been some more findings that I have posted over at the TypeORM issue tracker.

https://github.com/typeorm/typeorm/issues/6138

Basically, I have a workaround for the time being. I am not sure how stable it is, and that another issue won’t just pop up, but it seems that I need to name the property to the name of the column. There is a mismatch within TypeORM, where suddenly it wants to use the property name to find the column, which doesn’t find anything.
