Not able to run "find" query in remote mongodb collection using MongoClient in Node.js application -

- 

var express = require("express"); var bodyparser = require('body-parser'); var path    = require("path"); var objectid = require('mongodb').objectid; var mongoclient = require('mongodb').mongoclient,   format = require('util').format; var uri = 'mongodb://ac-00072810.devapollogrp.edu:27017/devdb';  mongoclient.connect(uri,function(err,db){      db.collection('transactionstatus',function(err,collection){          if(err){             throw err;         }         else{             collection.find({}).foreach(function(err,doc){                 console.log(doc);             });         }     }); });

getting error: 

[apol@ac-00067394 nodejs-testapp]$ node server.js body-parser deprecated bodyparser: use individual json/urlencoded  middlewares server.js:15:9 body-parser deprecated undefined extended: provide extended option  node_modules/body-parser/index.js:105:29 running @ port 3001 undefined

(note: mongodb version:3.0.2,node version:0.12.7, express version:4.12.4)

from mongo shell able details successfully. when trying fetch data using mongoclient form application getting error "undefined". tried possibilities. don't know doing wrong.

thanks in advance :)

at glance looks you're getting [foreach][1] behaviour wrong. callback passed foreach accepts 3 params: currentvalue, index , array, respectively, since it's core javascript function , not node-specific (which why followed err, doc convention).

try in else block:

collection.find({}).toarray(function(err, docarray){     console.log(docarray); });

i realize question might seem trivial some, it's these types of things find myself fighting quite bit , want make sense of despite seeming losing battle in .net (for me anyway). so, if following: using system.web; ... applicationuser user = system.web.httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); that produces error in title , red getowincontext() , error cannot resolve symbol 'getowincontext()' however, if following (remove system.web in front of httpcontext ), works expected (or @ least no errors): using system.web; ... applicationuser user = httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); however, if (same line that's working using system.web commented out): //using system.web; ... applicationuser user = httpcontext.getowincontext().getusermana...

mercurial graft feature, can it copy? -

-
there new feature in mercurial 3, called 'graft' (graft local). job of moving change-set different branch. is there way "copy" change-set branch? i interested in in moving stuff qa branch production branch, still need code reside in qa. want copy. found , have tried few things, maybe it'll become clear more tinkering , reading... does have better way of 'cherry picking' change-sets move cross branch (or trunk)??? graft copies changesets, doesn't move them. hg graft (emphasis mine): this command uses mercurial's merge logic copy individual changes other branches without merging branches in history graph. known 'backporting' or 'cherry-picking' . default, graft copy user, date, , description source changesets.
