i facing issue when failover happens in mongodb replica set. app fails reconnect newly elected primary server , fails perform subsequent write operations. restarting app reconnects successfully. the failover happens instantly , new primary elected. however, app fails connect new primary. mongodb version: 3.2.6 mongoose version: 4.3.4 node.js version:0.10.26 any appreciated. i have primary, secondary , arbiter set running in 3 different nodes. how connect using mongoose , failover works fine. mongoose.connect('mongodb://user:pwd@a.com:27017,b.com:27017,c.com:27017/dbname'); so, expect mongodb:// variables.

i have complex object (a user object) has nested arrays , nested objects within it. i have search filter relatively complicated (checkboxes determining items returned, along search input). currently search in object so: for(var key in item){ if(item[key] && item[key].length && string(item[key]).tolowercase().indexof($rootscope.filt.searchfilter.tolowercase()) !== -1){ realsave = true; } } however, works first layer of objects within item; need search objects within objects. how can this? simpler way above? (note, can't use ng-repeat="item in items | searchfilter" needs parse checkboxes , return values accordingly. try realsave = (json.stringify(item).indexof($rootscope.filt.searchfilter.tolowercase()) !== -1) (it's long line, scroll right) it transform whole object single string, can search sub-string you're looking anywhere inside it.

i'm preparing sequence diagram project. made following sequence diagram retailer updating inventory it's confusing me because first time use technique real project.i have used database object here , don't know whether right or wrong. , thing need clarify using updating meant both editing/add new item inventory. wrong way? or else can draw separately? the following image part of updating process, 1 take , correct me if did mistake.(updateui- user interface).thanks in advance. it not right. there couple of issues: your database never issue messages actions inside db not exposed. call crud outside db. you mix synch/asynch (likely unwillingly). filled arrows synch, unfilled ones asynch. main page v in mvc , updateui c. controller act on click user , interact db. so guts here more reasonable sketch:

let me explain problem giving example: imagine creating blog application in users can leave comments, need ensure if user human or not. keep in mind due limitations, can't use google recaptcha, have create own captcha code. so far there no problem since there bunch of samples on internet , of them use sessions keep last created code , of them use encrypted key, in url or hidden input in forms. firstly, if use sessions i'm not able display several blog posts contain unique captcha code can validate them after user submission because keep last generated random code. secondly, if use encrypted key , reveal in output html or in query string easy robots use generated key several times unless store these keys after submission. if choose use disposable keys have search database every time prevent generating duplicated random code. the question what's best approach let users open several posts , leave comment each 1 less code , i/o complexity.
