Current behavior

When upgrade to version 5.0.0. I cannot make any query to my database.

Expected behavior

Should be working like version 4.0.0

Minimal reproduction of the problem with instructions

Here a simple repository. It is working on version 4.0.0. Then when you upgrade, it’s not working anymore. The working part of typegoose is existingMongoose: mongoose.

import * as mongoose from 'mongoose';
import { prop, Typegoose } from 'Typegoose';

export class UserSchema extends Typegoose {
  @prop({ required: true })
  firstName!: string;

  @prop({ required: true })
  lastName!: string;

  @prop({ required: true })
  username!: string;

  @prop({ required: true })
  password!: string;
}

export const User = new UserSchema().setModelForClass(UserSchema, {
  schemaOptions: { collection: 'Users', timestamps: true },
  existingMongoose: mongoose
});

What is the motivation / use case for changing the behavior?

First when using mongo in nest project, I prefer using Typegoose. It offers a better schema declaration and typings. It is similar to sequelize-typescript when it comes to mongo design. It saving a lot of time to declare interfaces for every mongo schema.

Environment

Nest version: 5.0.1
 
For Tooling issues:
- Node version: 8.10.0
- Platform:  Windows

@Dominic-Preap ok sounds good.

@kamilmysliwiec I’ve answered my own questions. For anyone looking at this in the future, you can get access to the connection by injecting @Inject('DbConnectionToken') private readonly connection: mongoose.Connection into the constructor of where you need to use it.

@MumblesNZ @kamilmysliwiec I think I’m gonna bypass this issue cause I’ve created the mongoose module using https://docs.nestjs.com/recipes/mongodb and It is working for me.
