Updating model from directive in angularjs -


i have directive drag , drop.

the drag , drop works well, have problem updating model. after drop text textarea, text showing ok, model not updating.

what missing here?

//markup

 <textarea drop-on-me id="editor-texto" ng-trim="false" ng-model="mymodel"  name="templatesms.template">test.</textarea>

//directive

angular   .module('clinang')   .directive('dragme', dragme)   .directive('droponme', droponme);  dragme.$inject = [];  function typeintextarea(el, newtext) {   var start = el.selectionstart   var end = el.selectionend   var text = el.value   var before = text.substring(0, start)   var after  = text.substring(end, text.length)   el.value = (before + newtext + after)   el.selectionstart = el.selectionend = start + newtext.length   el.focus() }  function dragme() {   var ddo = {     restrict: 'a',     link: function(scope, element, attrs) {       element.prop('draggable', true);       element.on('dragstart', function(event) {         event.datatransfer.setdata('text', event.target.id)       });     }   };   return ddo; } droponme.$inject = []; function droponme() {   var ddo = {     restrict: 'a',     link: function(scope, element, attrs) {       element.on('dragover', function(event) {         event.preventdefault();       });       element.on('drop', function(event) {         event.preventdefault();         var data = event.datatransfer.getdata("text");         var x=document.getelementbyid(data);         typeintextarea(event.target,x.getattribute('data-value'))       });     }   };   return ddo; }

update textarea model inside typeintextarea function , using $apply run digest cycle update model change across whole app. current structure of directives link functions you'll need pass scope typeintextarea function (as parameter). function be:

function typeintextarea(scope, el, newtext) {   var start = el.selectionstart   var end = el.selectionend   var text = el.value   var before = text.substring(0, start)   var after  = text.substring(end, text.length)   el.value = (before + newtext + after);   scope.mymodel.textnote = el.value;   el.selectionstart = el.selectionend = start + newtext.length;   el.focus(); }

and droponme function be:

function droponme() {   var ddo = {     restrict: 'a',     link: function(scope, element, attrs) {       element.on('dragover', function(event) {         event.preventdefault();       });       element.on('drop', function(event) {         event.preventdefault();         var data = event.datatransfer.getdata("text");         var x=document.getelementbyid(data);         typeintextarea(scope, event.target,x.getattribute('data-value'))         scope.$apply();       });     }   };   return ddo; }

check out example (i don't know element you're dragging e.g. i've considered span element & used innerhtml ):

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 ...
