Membuat hubungan Kunci Asing di Mongoose

Periksa Kode yang diperbarui di bawah ini, khususnya bagian ini:{type: Schema.Types.ObjectId, ref: 'Ingredient'}

var mongoose = require('mongoose');
var Schema = mongoose.Schema;

var IngredientSchema = new Schema({
    name: String
});

module.exports = mongoose.model('Ingredient', IngredientSchema);

var mongoose = require('mongoose');
var Schema = mongoose.Schema;

var RecipeSchema = new Schema({
    name: String,
    ingredients:[
      {type: Schema.Types.ObjectId, ref: 'Ingredient'}
    ]
});

module.exports = mongoose.model('Recipe', RecipeSchema);

Untuk Menyimpan:

var r = new Recipe();

r.name = 'Blah';
r.ingredients.push('mongo id of ingredient');

r.save();
