Question

我正在使用SimpleSchema和Meteor来构建数据库条目。

问题是，我有一个数组数组，定义的模式不起作用。

这是一个文档示例：

Courses.insert({  
   "persian_title":"persian title",
   "english_title":"english title",
   "free_for_all":true,
   "price":1000,
   "is_offer":false,
   "offer_price":500,
   "Seasons":[  
      {  
         "title":"first Season",
         "free_for_all":false,
         "Episodes":[  
            {  
               "title":"first Episode",
               "length":"12:10:00",
               "url":"test"
            },
            {  
               "title":"second Episode",
               "length":"0:10:00",
               "url":"test"
            },
            {  
               "title":"third Episode",
               "length":"14:10:00",
               "url":"test"
            }
         ]
      },
      {  
         "title":"Second Season",
         "free_for_all":false,
         "Episodes":[  
            {  
               "title":"first Episode",
               "length":"12:10:00",
               "url":"test"
            },
            {  
               "title":"second Episode",
               "length":"0:10:00",
               "url":"test"
            },
            {  
               "title":"third Episode",
               "length":"14:10:00",
               "url":"test"
            }
         ]
      }
   ]
})

和架构：

Courses = new Mongo.Collection("courses");
var Schemas = {};
Schemas.Courses = new SimpleSchema(
    {
        persian_title: {
            type: String
        },
        english_title: {
            type: String
        },
        free_for_all: {
            type: Boolean
        },

        price: {
            type: Number
        },
        is_offer: {
            type: Boolean
        },
        offer_price: {
            type: Number
        },


        // Seasons

        "Courses.$.Seasons": {
            type: [Object]
        },
        "Courses.$.Seasons.$.title": {
            type: String
        },
        "Courses.$.Seasons.$.free_for_all": {
            type: Boolean
        },
        // Episodes
        "Courses.$.Seasons.$.Episodes": {
            type: [Object]
        },
        "Courses.$.Seasons.$.Episodes.title": {
            type: String
        },
        "Courses.$.Seasons.$.Episodes.length": {
            type: String,
            max: 8
        },
        "Courses.$.Seasons.$.Episodes.url": {
            type: String,
            max: 1000
        }


    });
Courses.attachSchema(Schemas.Courses);

问题是如何为数组数组定义Schema？

Answer 1

您必须使用PackageManager.COMPONENT_ENABLED_STATE_DISABLED_USER在架构中明确定义Seasons.$.Episodes。定义Seasons数组对象的模式，如下所示：

type: [Object]

如何在Meteor中定义嵌套数组的模式？
