Typegoose not working with @nestjs/mongoose v5.0.0 about mongoose

@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.

Are you sure that this issue comes from the Nest package rather than from the updated mongoose underneath?

[Dominic-Preap]

@kamilmysliwiec Yes, I've tried to lower the mongoose, but the issue is still there.
It seems that in your code, you are using mongoose.createConnection() on v5 and mongoose.connect() on v4. So I lost my ability to use mongoose as a singleton when I call existingMongoose: mongoose because mongoose is never connect to database at all.

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

Right. I'll think how we can solve this issue.

@Dominic-Preap I've been working on a separate issue which also needs a reference to the connection db within my code. There seems to be a connections array in mongoose which has a reference to all the connections, when I inspect with nodejs debugger my db is the second item in that array. You can't use @types/mongoose if you are using this method as it's not listed. You could have a look at this array and see if you can find you connection/db to pass into Typegoose? For example if your db connection is setup as the second connection the below may work?

import * as mongoose from 'mongoose';
export const User = new UserSchema().setModelForClass(UserSchema, {
  schemaOptions: { collection: 'Users', timestamps: true },
  existingMongoose: mongoose.connections[1]
});

@kamilmysliwiec is there any way to get a reference for the db that we can inject into our controllers when we use the MongooseModule.forRoot method?

@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.
