我从麻雀开始,我想知道如何做这种类型的配置：
食谱有不同的成分@H_301_3@
我有两个模型：@H_301_3@
成分和食谱：@H_301_3@
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);
解决方法
检查下面的更新代码,特别是这部分：{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);
保存：@H_301_3@
var r = new Recipe();
r.name = 'Blah';
r.ingredients.push('mongo id of ingredient');
r.save();
