以下服務器方法因爲找不到用戶而導致重複密鑰錯誤。一個典型的查詢是:{服務:{Facebook的:{ID:「XXXX」}}}在服務器上查找流星用戶

Meteor.methods 
    getUser: (query, data = {}) -> 
    user = Meteor.users.findOne(query) 
    return user if user? 
    user = _.extend(data, query) 
    user._id = Meteor.users.insert user 
    return user 

這是我的理解是服務器的方法有機會獲得在集合中的所有文件,爲什麼不能在用戶找到但插入由於重複的Facebook ID失敗?

這在我的osx dev環境中完美工作,但在我的ubuntu服務器(捆綁)上失敗並且在NODE_ENV = production下運行。

這裏是日誌輸出:

data: { services: { facebook: { id: 'xxxx' } } } (the query provided to getUser) 
data: undefined (the result of findOne) 
data: Exception while invoking method 'getUser' MongoError: E11000 duplicate key error index: thunderstruck.users.$services.facebook.id_1 dup key: { : "xxxx" }

我剛剛得到它的格式化查詢是這樣的:{「services.facebook.id」:「xxxx」}似乎嵌套太深了。我使用node-inspector在服務器上嘗試了各種查詢,發現嵌套3深度的查詢總是返回undefined。仍然不清楚爲什麼深層嵌套在OSX上工作並在Linux上失敗。 –

這些都是不同的MongoDB的查詢,你一定要你切換到虛線樣式。請參閱Mongo Dot Notation文檔。

Meteor.users.find({"services.facebook.id": "foo"}) 

將返回任何具有您正在查找的嵌入屬性值爲foo的文檔。

Meteor.users.find({services: {facebook: {id: "foo"}}}) 

只匹配與正是該結構的文檔。如果嵌入式Facebook文檔有其他字段,則不匹配。生產數據庫中的文檔很可能具有更多字段,因此您無法獲得匹配結果。
