Why are my array's objects being destroyed on meteor insert? - mongodb

Question

This might have to do with me updating Meteor this morning.
Anyway here is some code:
//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))
It appears that insert is destroying the objects in the array somehow.
My original code has been working for weeks. Only this morning has it stopped. (There are other things besides meteor update that could be involved. I have added simpleschema and collection2. I also change some publish methods, but this code is fully run on the server.
Here is more code:
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)
_.each(paragraphs, function (paragraph, p) {
// console.log("paragraph", paragraph)
article.paragraphs[p] = {}
article.paragraphs[p].read = false
article.paragraphs[p].text = paragraph
article.paragraphs[p].index = p
// console.log("paragraphs[p]", article.paragraphs[p])
var sentences = splitParagraphIntoSentences(paragraph)
article.paragraphs[p].sentences = []
_.each(sentences, function (sentence, s) {
if (sentence !== "") {
article.paragraphs[p].sentences[s] = {}
// console.log("sentence", sentence)
article.paragraphs[p].sentences[s].text = sentence
article.paragraphs[p].sentences[s].read = false
// console.log("paragraphs[p].sentences[s]", article.paragraphs[p].sentences[s])
//console.log('splitter', splitSentenceIntoWordsForward(sentence))
var wordsForward = splitSentenceIntoWordsForward(sentence)
UserSentences.insert({user: Meteor.userId(), words: JSON.parse(JSON.stringify(wordsForward))})
// console.log("wordsForward new", wordsForward, JSON.stringify(wordsForward))
article.paragraphs[p].sentences[s].forward = {}
article.paragraphs[p].sentences[s].forward.words = wordsForward
// console.log('wordsForward', JSON.stringify(wordsForward))

Answer 1

Collection2 was causing the problem.
This is how I got around it:
UserSentences.insert({user: Meteor.userId(), words: wordsForward},
{bypassCollection2: true})
