coffeescript - collection.find "fields" option interfere with "selector" argument -


i'd publish online users list clients, , exclude 'username' properties due security reasons. have following server side publish:

meteor.publish 'onlineusers', ->     users = meteor.users.find         "services.resume.logintokens.0":             $exists: true

and works fine, producing following output:

console.log users.fetch()  >> [{         id: 'kfney2anhwzc4w4zx',        createdat: fri jan 31 2014 20:04:40 gmt+0400 (msk),        <...>    },     {   _id: 'tlnbhoqcex46v5l7s',        createdat: fri jan 31 2014 20:05:04 gmt+0400 (msk),        ...    }]

but add "fields" option publish arguments, result empty list:

meteor.publish 'onlineusers', ->     users = meteor.users.find         "services.resume.logintokens.0":             $exists: true         fields:             username: true      console.log users.fetch()  >> []

so questions are:

  1. does "find" method query fields included result cursor?
  2. if it's so, best practice publish subset of fields each user?

upd: andrew mao noticed, had mistake while using coffeescript syntax. without preceeding comma fields option part of first argument object. correct method call should following:

meteor.users.find     "services.resume.logintokens.0":         $exists: true     ,          fields:             username: true

you're using coffeescript , making mistake syntax. fields needs key in second argument find, not first one. 1 way can write is

meteor.publish 'onlineusers', ->     users = meteor.users.find {"services.resume.logintokens.0": {$exists: true}},         { fields:             { username: true }         }

all curly braces optional above, , used show structure. can omit them once become more familiar coffeescript. all-important comma has between arguments somewhere.

c# - OpenXML hanging while writing elements -

i have program pulls data database, caches file , exports data multiple formats (excel, excel 2003, csv). i'm using openxml sdk 2.0 excel work. these export processes run in parallel (using parallel.foreach ), , amount of data can pretty large - e.g. csvs 800mb. during these larger exports, i've noticed writing of xml documents hang. instance, if have 8 exporting in parallel, @ point "pause". hang around same point: //this.writer openxmlwriter created worksheetpart. this.writer.writeelement(new cell() { cellvalue = new cellvalue(value), datatype = cellvalues.string }); when happens, pause debugger (vs2013 in case) , notice threads blocking around same portion of code - bit deeper in openxml sdk - stem call openxmlwriter.writeelement . i dug through source using justdecompile didn't find answers. appears there intermediary stream in use writing isolated storage , is, reason, blocking. underlying stream each of these filestream . here screenshot ...
