Populate a query with mongoose in typescript

I'm having trouble populating my user model with typescript. I have a property of the user's scheme which is the reference to his profile. To implement mongoose with typescript I had to define a tpo / interface in addition to the schema. My problem is that I do not know what type I have to assign to the profile property. Because if I run the query without populating it, it will be an "ObjectId", but if I populate it will contain the whole profile document.

export type UserModel = mongoose.Document & {
  name: string;
  username: string; 
  email: string;
  password: string; 
  profile: Schema.Types.ObjectId; // If I leave this property with this type, in case I populate a typescript query it would give me an error. 
};


export const UserSchema = new Schema({
  name: {
    type: String,
    required: true
  },
  username: {
    type: String,
    required: true,
    unique: true
  },
  email: {
    type: String,
    unique: true,
    required: true
  },

  password: {
    type: String,
    required: true
  },
  profile: {
    type: Schema.Types.ObjectId,
    ref: "Profile"
  }
});

export default model<UserModel>("User", UserSchema);

My problem is that I do not know what type I have to assign to the profile property.

You are going to need to define 2 types/interfaces. 

export default model<UserModel>("User", UserSchema);

This export will have to use a different interface in which you have the populated "Profile" document.

For the schema itself you can leave it as an objectID type.

Try to set the populate pointing to the model, this should do the trick

 User.find({}).populate([{"path":"profile", "model":"Profile" }])
