Question

这可能与我今天早上更新Meteor有关。

无论如何，这里有一些代码：

//this returns Words properly    
console.log('splitter', splitSentenceIntoWordsForward(sentence)) 

var wordsForward = splitSentenceIntoWordsForward(sentence)

 //if I remove this line then everything works.
UserSentences.insert({user: Meteor.userId(), words: wordsForward})

//If I don't remove the line above, this prints an array of empty objects like this: [ { }, { } ]
console.log("wordsForward new", wordsForward, JSON.stringify(wordsForward))

看来insert正在以某种方式破坏数组中的对象。

我的原始代码已经工作了好几周。只有今天早上才停止。（除了meteor更新之外还有其他的东西可以参与。我添加了simpleschema和collection2。我也改变了一些发布方法，但是这个代码完全在服务器上运行。

这是更多代码：

UserSentences = new Mongo.Collection('userSentences')
Schemas.UserSentences = new SimpleSchema({
    words: {
        type: [Object],
        label: 'Words',
        optional: false
    },
    user: {
        type: String,
        label: 'user id',
        optional: false
    }
})
UserSentences.attachSchema(Schemas.UserSentences)

Meteor.methods({
    createArticle: function (text, title, share) {
        var article = {}
        var wordsArray = []
        article.title = title
        article.userID = Meteor.userId()
        article.text = text
        article.public = share
        var id = Articles.insert(article)
        article.paragraphs = []
        var paragraphs = splitArticleIntoParagraphs(text)
        console.log("paragraphs", paragraphs)
        paragraphs = paragraphs.filter(String)
        console.log('paragraphs w/o empties', paragraphs)

Answer 1

Collection2导致了这个问题。

这就是我解决这个问题的方法：

UserSentences.insert({user: Meteor.userId(), words: wordsForward},
                     {bypassCollection2: true})

为什么我的数组的对象在流星插入时被破坏了？
