流星尝试创建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东西，并使用jQuery在其他地方更新它(给我一个休息时间，我是新来的)，之后我需要能够单击它并显示一些UI东西，这意味着ID.因此，我设置了ID变量，然后尝试，然后尝试在click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);
},

...

应该可以正常工作，但是我收到以下错误消息:

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

Uncaught Error: Invalid hexadecimal string for creating an ObjectID

一个断点显示该ID既是字符串，又是新插入文档的ID.这里可能出什么问题了?

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'}传递到 new MongoCollection() 来告诉Meteor使用Mongo样式ID. ，或者(可能更容易)如果newMessageID的值是insert()返回的_id，则仅使用newMessageID而不是new Mongo.ObjectID(newMessageID).

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().
