以下服务器方法抛出重复键错误,因为找不到用户。典型的查询如下:{services: {facebook: {id: 'XXXX'}}}。
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
据我了解,服务器方法可以访问集合中的所有文档,那么为什么无法找到用户却因为重复的Facebook ID而插入失败呢?
在我的OSX开发环境中,这个功能运行得非常完美,但在我的Ubuntu服务器(已捆绑)上以及在NODE_ENV=production下运行时会失败。
以下是日志输出:
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" }
