Mongoose Schema Types @Ref()

[Nareshtekula]

Hi @Romakita , I am migrating my project from js to Ts.ED
Issue in using Mongoose Schema Types@Ref()
Workspace.ts

import { Required } from "@tsed/common";
import { Model, Ref, ObjectID } from "@tsed/mongoose";
import { Workspace } from "../workspace/Workspace";

@Model()
export class User {
    @ObjectID("id")
    _id: string;

    @Required()
    name: string;

    @Ref(Workspace)
    workspace: Ref<Workspace>;
}

User.ts

import { Required} from "@tsed/common";
import {Model, Ref, ObjectID} from "@tsed/mongoose";
import { User } from "../users/User";
@Model()
export class Workspace {
  @ObjectID("id")
  _id: string;

  @Required()
  name: string;

  @Ref(User)
  createdBy: Ref<User>;
}

Injecting User Model in service.
UserService.ts

import { Inject, Service } from "@tsed/common";
import { MongooseModel } from "@tsed/mongoose";
import { User } from "../../models/users/User";

@Service()
export class UserService {
  @Inject(User)
  private User: MongooseModel<User>;

  async find(id: string): Promise<User> {
    const user = await this.User.findById(id).exec();
    return user;
  }

}

Getting below error.

Hello @Nareshtekula

See you

Hi @Romakita
Same Error.
[2020-07-09T17:56:41.735] [ERROR] [TSED] - TypeError: Cannot read property 'prototype' of undefined

Issue is when User Model has @Ref (Workspace ) and Workspace Model has @Ref(User).

It works if i remove @Ref() from any one model.

Thank you.

[Romakita]

Ok I'll try to reproduce your bug :)

[Romakita]

Ok I missed, you have a circular reference :)

So to avoid this, try this example:

import { Required } from "@tsed/common";
import { Model, Ref, ObjectID } from "@tsed/mongoose";
import { Workspace } from "../workspace/Workspace";

@Model()
export class User {
    @ObjectID("id")
    _id: string;

    @Required()
    name: string;

    @Ref("Workspace") // add quote. The Workspace ref will be resolved later
    workspace: Ref<Workspace>;
}

See you
Romain
