更改猫鼬架构视图模型

Question

我有问题，在猫鼬的相关模式： 我有3层架构：

var recipeProductSchema = new mongoose.Schema({ 
    product: { type: mongoose.Schema.Types.ObjectId, ref: 'Product' }, 
    productWeight: Number 
}, {toJSON: {virtuals: true}}); 

var recipeSchema = new mongoose.Schema({ 
    name: String, 
    products: [RecipeProduct] 
}) 

var productSchema = new mongoose.Schema({ 
    name: { 
     type: String, 
     required: true 
    }, 
    weight: { 
     type: Number, 
     required: true 
    }, 
    price: { 
     type: Number, 
     required: true 
    } 
}) 

当我想创建一个产品配方我送：

{ 
    "name": "Cake", 
    "products": [ 
     { 
      "product": "597a517b7c2e8508c8cc3f3a", 
      "productWeight": 50 
     } 
    ] 
} 

但是，当我得到关于食谱的详细信息我得到这个：

{ 
    "_id": "597f7d0ce25d1413149aa30d", 
    "name": "Cake", 
    "products": [ 
     { 
      "product": { 
       "_id": "597a517b7c2e8508c8cc3f3a", 
       "name": "Sugar", 
       "weight": 400, 
       "price": 40 
      }, 
      "productWeight": 50, 
      "_id": "597b825a61736b1adcb0ed0f", 
      "productPrice": "5.00", 
      "id": "597b825a61736b1adcb0ed0f" 
     } 
    ] 
} 

是否有可能使这两个json相似吗？ 因为在编辑配方视图中，我不想在数据发送之前更改配方的产品对象;

我想给这个JSON：

{ 
    "name": "Cake", 
    "products": [ 
     { 
      "product": { 
       "id": "597a517b7c2e8508c8cc3f3a" // or "_id" 
      }, 
      "productWeight": 50 
     } 
    ] 
} 

而且我想获得：

{ 
    "_id": "597f7d0ce25d1413149aa30d", 
    "name": "Cake", 
    "products": [ 
     { 
      "product": { 
       "_id": "597a517b7c2e8508c8cc3f3a", 
       "name": "Sugar", 
       "weight": 400, 
       "price": 40 
      }, 
      "productWeight": 50, 
      "_id": "597f7d0ce25d1413149aa30e", 
      "productPrice": "5.00", 
      "id": "597f7d0ce25d1413149aa30e" 
     } 
    ] 
}

尝试做一个儿童/父母关系

var recipeProductSchema = new mongoose.Schema({ 
    product: [productSchema], 
    productWeight: Number 
}, {toJSON: {virtuals: true}}); 

var recipeSchema = new mongoose.Schema({ 
    name: String, 
    products: [recipeProductSchema] 
}) 

var productSchema = new mongoose.Schema({ 
    name: { 
     type: String, 
     required: true 
    }, 
    weight: { 
     type: Number, 
     required: true 
    }, 
    price: { 
     type: Number, 
     required: true 
    } 
}) 

，并做了$push进入您的创建功能。

您还可以在您的获取功能中使用猫鼬填充
