Meteor 的 todos 示例运行良好。但是,当我向 Todos 和 Lists 集合添加架构时,我不断收到“错误:列表 id 必须是一个对象”。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 文件中的新架构:
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);
其他一切都没有改变。
在我开始流星之前,我做了一个“流星重置”。
这是尝试将新列表的 _id (list_id) 附加到 Todos 架构中的 listId 对象时来自 bootstrap.js 文件的错误:。. . {名称:“Favorite Scientists”,项目:[“Ada Lovelace”、“Grace Hopper”、“Marie Curie”、“Carl Friedrich Gauss”、“Nikola Tesla”、“Claude Shannon”]}];
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.
});
});
(STDERR) throw(ex);
