Question

我从角度

获得此数据

 {
     "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"
        }
        ]
}

我希望将它保存在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]
          });

以及它如何保存到服务器控制器中的模型

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

当我使用这个Schema和这个控制器时，我得到除了name和ObjectId之外的集合中的空记录。如何创建正确的架构和控制器？

Answer 1

创建架构后，您需要创建一个猫鼬模型，然后您可以保存它。尝试这样的事情：

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 } );

Answer 2

当然，以上答案有效，请将其视为替代。

var defaultArray = ["A","B","C"];
var schemaDef = mongoose.Schema(       
  permission: { type: Array, default: defaultArray },
);
