javascript - Cannot send a file through FormData object in http request. Formidable cannot find any file in server end -


i want upload file angularjs in client side , nodejs , express in server side. in angular, i'm using lf-ng-md-file-input directive upload file. in server side, i'm using package formidable parse multipart form data. here html code:

<lf-ng-md-file-input lf-submit-label="upload" lf-files="files"      submit lf-on-submit-click="onsubmitclick"      ng-change="onsubmitfileschange()" progress> </lf-ng-md-file-input>

and angular code submit click:

$scope.onsubmitclick = function(files) {     console.log(files[0])            //this shows file object correctly     console.log($scope.file)     var formdata = new formdata()     angular.foreach(files,function(obj){         if(!obj.isremote){             console.log(obj)             formdata.append('files', obj.lffile);         }     });     formdata.append('source', $scope.file.source);     formdata.append('batch', $scope.file.batch);     (var pair of formdata.entries()) {         console.log(pair[0]+ ', ' + pair[1]);      }     $http.post(config.serverurl + "/upload", formdata, {         transformrequest: angular.identity,         headers: {'content-type': undefined}     }).then(function(result){         // sometingh          console.log(result)                       },function(err){         // sometingh     }); }

this server side code in node js:

var formidable  = require('formidable') app.use(express.static(__dirname + '/public')) app.post('/upload',function(req,res){     var form = new formidable.incomingform();     form.uploaddir = __dirname +'/public/uploads';     form.keepextensions = true;     console.log(form)     console.log(req.body)     //file upload path     form.parse(req, function(err, fields, files) {         //you can fields here         console.log("parsing")         console.log(fields)         console.log(files)     });     form.on ('filebegin', function(name, file){         console.log("file begin")         file.path = form.uploaddir + "/" + file.name;         //modify file path     });     form.on('progress', function(err) {         console.log("on progress")     });     form.on('field', function(err) {         console.log("fields found")     });     form.on('file', function(err) {         console.log("file found")     });     form.on('error', function(err) {         console.log("error occured")         res.sendstatus(400);     });     form.on('aborted', function(err) {         console.log("aborted")     });     form.on ('end', function(){         console.log("in end")         res.sendstatus(200);         //when finish process         }); });

but problem is, in server side, req.body showing other fields there nothing found in form. shows aborted due timeout. form.parse not working @ all.

please suggest how can find file in form object @ server side

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
