Creating a Foreign Key relationship in Mongoose

Question

I'm beginning with Mongoose and I want to know how to do this type of configuration:

A recipe has different ingredients.

I have my two models:

Ingredient and Recipe:

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

Answer 1

Check Updated code below, in particular this part: {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); 

To Save:

var r = new Recipe();  r.name = 'Blah'; r.ingredients.push('mongo id of ingredient');  r.save();
