Meteor 在尝试创建 ObjectID 时返回无效的十六进制字符串错误? [英] Meteor returns invalid hexadecimal string error trying to create ObjectID?

问题描述

我正在向数据库中插入一些内容并使用 jQuery 在其他地方更新它(让我休息一下，我是新手)，之后我需要能够单击它并显示一些 UI 内容，这意味着获取ID.所以我设置了 ID 变量，然后尝试然后尝试在点击事件中使用它:

I'm inserting some stuff into the database and updating it elsewhere using jQuery (give me a break, I'm new), after which I need to be able to click it and display some UI stuff, which means getting the ID. So I set the ID variable and then try and and then try and use it in the click event:

...

"click .message-entry" : function (e) {
    var id = this._id || new Meteor.Collection.ObjectID(newMessageId);
    Session.set('singleMessageId', id);
},

...

原则上应该可以工作，但是我得到以下错误返回:

Should work in principle, however I get the following error returned:

未捕获的错误:用于创建 ObjectID 的十六进制字符串无效

断点显示ID既是字符串又是新插入文档的ID.这里可能出了什么问题?

A breakpoint reveals that the ID is both a string and the ID of the newly inserted document. What could be going wrong here?

推荐答案

默认情况下，Meteor 不使用 Mongo 的十六进制对象 ID.您可以通过将 {idGeneration: 'MONGO'} 传入 new MongoCollection()，或者(可能更容易)只使用 newMessageID 而不是 new Mongo.ObjectID(newMessageID)，如果newMessageID的值是insert()返回的_id.

By default, Meteor doesn't use Mongo's hexadecimal object IDs. You could either tell Meteor to use Mongo style IDs by passing {idGeneration: 'MONGO'} into new MongoCollection(), or (probably more easily) just use newMessageID instead of new Mongo.ObjectID(newMessageID), if the value of newMessageID is the _id returned by insert().
