javascript - No connection events are being fired - Mongoose 4.7.1 & Express -


i having issues connecting express app mongodb via mongoose. there no complicated set up, basic:

var mongoose = require('mongoose');  mongoose.connect('mongodb://localhost/homeapp');  var db = mongoose.connection;  db.on("connecting", function(){     console.log("connecting db..."); });  db.on('connected', function(){     console.log('connected db'); });  db.on('error', function(error){     console.log('error'); });

simple enough, right? none of these events being fired. mongo running ok , it's on default port. have tried changing localhost 127.0.0.1 , checked contents of etc/hosts file , seems ok. if mangle uri string like:

'mongoldb://lclhost/homeapp'

i error saying cannot connect, expected seems connection being made/attempted nothing happening.

i've logged contents of db.db console , noticed connected: false, suggests it's not attempting connect?

any ideas? mongoose 4.7.1 running on macos sierra 10.12.5.

thanks in advance!

figured it! tried using mongodb client without mongoose , worked expected, knew connection ok , left blame mongoose.

turns out not using 4.7.1 had thought, , running npm install mongoose --save had in fact installed version 3.x, not compatible latest version of mongodb according mongoose docs. http://mongoosejs.com/docs/compatibility.html

upgrading version number in package.json file 4.7.1 fixed issue.

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer

jquery - Responsive Navbar with Sub Navbar -

good day, forgive me nav vocabulary not best. if question confusing apologize. i'm working on navigation bar needs centered on page @ 768px , above. items in nav open (or perhaps toggle) subnav lives directly below. these nav should appear centered on page. i have been able work through responsive portion of nav bar, having main items align vertically , sub nav menu of each item roll out below, , gave them indent separation. working well. however, issue not responsive side, behavior @ width greater 768px. happens toggling menu's sub navigation pushes other main items down page below sub nav. here's code: $(document).ready(function () { //stick in fixed 100% height behind navbar don't wrap $('#slide-nav.navbar-inverse').after($('<div class="inverse" id="navbar-height-col"></div>')); $('#slide-nav.navbar-default').after($('<div id="navbar-height-col"></d
