Anda dapat menggunakan konsep Virtuals . Begini caranya:
Ubah file skema Anda sebagai berikut:
//---------------------------------------------------
const gameSchema = new mongoose.Schema({
title: String,
rating: { type: Number, min: 0, max: 100 },
genres: [Number],//here you have an array of id of type Number as yours, no ref
});
const GenreSchema = new mongoose.Schema({
id: { type: Number },
name: String,
description: String,
});
gameSchema.virtual("games", {
ref: "Genres",//this is the model to populate
localField: "id",//the field used to make the populate, it is the field that must match on the aimed Genres model <- here is the trick you want!!!
foreignField: "genres",//the field to populate on Games model
justOne: false,
});
gameSchema.set("toObject", { virtuals: true });//if you are planning to use say console.log
gameSchema.set("toJSON", { virtuals: true });//if you are planning to use say res.json
mongoose.model("Games", gameSchema);
mongoose.model("Genres", GenreSchema);
//-------------------------------------------------
Pada file yang Anda coba isi, letakkan ini di bagian deklarasi:
//-----------------------------------------------------
const Games = mongoose.model("Games", gameSchema);
//---------------------------------------------------
Last but not least, di mana Anda ingin mengisi:
//----------------------------------------------
Games.find({})
.populate("games")
.exec(function (error, games) {
//with games you can use things like game.field1, it is actually an JSON object! Print out games and see the fieds for your self, select one and call it using the dot notation!
console.log(games);
});
//---------------------------------------------
