Question

Meteor的todos示例运行良好。但是，当我向Todos和Lists集合添加了一个模式时，我不断得到＆＃34;错误：列表ID必须是一个对象＆＃34;。任何帮助将不胜感激。

添加了： meteor add aldeed：simple-schema meteor add aldeed：collection2

这是添加到collections.js文件的新架构：

Lists = new Mongo.Collection('lists');

var Schema = {};

Schema.Lists = new SimpleSchema({
  name: {
    type: String
  },
  incompleteCount: {
    type: Number
  }
});

Lists.attachSchema(Schema.Lists);

Todos = new Mongo.Collection('todos');

Schema.Todos = new SimpleSchema({
  listId: {
    type: Object
  },
  text: {
    type: String
  },
  createdAt: {
    type: Date
  }
});

Todos.attachSchema(Schema.Todos);

没有其他改变。

在我开始流星之前，我做了一次＆＃34;流星重置＆＃34;。

尝试将新列表的_id（list_id）附加到Todos架构的listId对象时，bootstrap.js文件中出现以下错误：。。。 {姓名：＆＃34;最喜欢的科学家＆＃34;，项目：[＆＃34; Ada Lovelace＆＃34;，＆＃34; Grace Hopper＆＃34;，＆＃34; Marie Curie＆＃34;，＆＃34; Carl Friedrich Gauss＆＃34;，＆＃34; Nikola Tesla＆＃34;，＆＃34;克劳德香农＆＃34; ] } ];

     var timestamp = (new Date()).getTime();
     _.each(data, function(list) {
       var list_id = Lists.insert({name: list.name,
         incompleteCount: list.items.length});

       _.each(list.items, function(text) {     //line 43
         Todos.insert({listId: list_id,        //line 44
                       text: text,
                       createdAt: new Date(timestamp)});
         timestamp += 1; // ensure unique timestamp.
       });
     });

class DragAndDrop { item: Item; documentBody: HTMLBodyElement; constructor(documentBody: HTMLBodyElement, item: Item) { this.documentBody = documentBody; this.item = item; this.documentBody.addEventListener("mousedown", this.onmousedown); } onmousedown = (event: MouseEvent): void => { if (CollisionDetector.pointInRect(event.clientX, event.clientY, this.item)) { // Similarly ... } } }返回新创建的对象的_id，这是一个字符串，因此list_id变量返回一个字符串并使您的架构无效。将Schema.Todos listId类型更改为String而不是Object。

Lists.insert()

获取错误：将模式添加到Meteor中的todos示例后，列表ID必须是对象
