node.js - 如何在 Mongoose 中保存对象数组

Question

我有这个来自角度的数据

 {
     "name": "Test name",
     "conditions": [
        {
         "id": "56a53ba04ce46bf01ae2bda7",
         "name": "First condition"             
        },
        {
         "id": "56a53bae4ce46bf01ae2bda8",
         "name": "Second condition"
        }
     ],
     "colors": [
        {
         "id": "56a545694f2e7a20064f228e",
         "name": "First color"
        },
        {
         "id": "56a5456f4f2e7a20064f228f",
         "name": "Second color"
        }
     ]
}

我想将它保存在 mongoDb 的 ProductSchema 中，但我不知道如何为此创建架构

var ProductSchema = new Schema({
    name: String,
    conditions:  [Array],
    colors: [Array]
});

以及如何将其保存到服务器 Controller 中的模型

 var product = new Products({
    name: req.body.name,
    conditions: req.body.conditions,
    colors: req.body.colors
});

当我使用此架构和此 Controller 时，我在集合中得到空记录，但名称和 ObjectId 除外。如何创建正确的 Schema 和 Controller ？

您需要在创建架构后创建一个 mongoose 模型，然后您可以保存它。试试这样的:

var ProductSchema = new Schema({
name: String,
conditions:  [{}],
colors: [{}]
          });

var Product = mongoose.model('Product', productSchema);

var product = new Product({
    name: req.body.name,
    conditions: req.body.conditions,
    colors: req.body.colors
});

product.save( function(error, document){ //callback stuff here } );
