Current behavior

In docs of https://docs.nestjs.com/techniques/mongodb the population example is shown as the following:

@Prop({ type: mongoose.Schema.Types.ObjectId, ref: 'Owner' })
owner: Owner;

But actually this is not correct, instead in reality owner is of type ObjectId. Only when explicitly populating the query owner ist of type Owner.

In the example the definition of CreateCatDto is not shown but if the types are used everywhere then the compiler would complain because there is a mismatch: When creating a new Cat one need to add owner of type ObjectId and not of type Owner as the compile would demand. Also when querying for Cat one will get an ObjectId while the compile thinks it is Owner.

Expected behavior

Provide a better example / best practice of population. Mongoose docs: https://mongoosejs.com/docs/typescript/populate.html
