使用Mongo和Keystone JS存储对象数组的字段类型

Question

我有一个模型，并且我需要一个字段来存储对象数组，但我不知道其结构。

用混合类型扩展基础架构无效

var Schema = mongoose.Schema;
MyList.schema.add({
ImageData: {type:Schema.Types.Mixed}, // for storing entire JS objects
});

我想保存的数据

 ImageData :  [ 
       { 
          "Uri":"Test.com",
          "Hash":"42e04950d6f11cd5350e3179083c7c7f",
          "Path":"/public/server/img/de29d68ab3594032bef70ead0b0d8fc2.jpg"
       },
       { 
          "Uri":"Test.com",
          "Hash":"42e04950d6f11cd5350e3179083c7c7f",
          "Path":"/public/server/img/de29d68ab3594032bef70ead0b0d8fc2.jpg"
       }
    ]

我的模特

Data.add({
    name: { type: String, required: false },
    Type: { type: Types.Select, options: 'New, Used,', index: true },
    ImageData: { type: Types.TextArray },
    content: {
        brief: { type: Types.Html, wysiwyg: true, height: 150 },
        extended: { type: Types.Html, wysiwyg: true, height: 400 },
    },
});
