javascript - polyline in rails using js -


i'm trying draw simple polylines in js (rails) ain't showing anything.

function drawlines() {     var flightpath = new google.maps.polyline({     path: flightplancoordinates,     geodesic: true,     strokecolor: '#ff0000',     strokeopacity: 1.0,     strokeweight: 25,     map:map     });  flightpath.setmap(map); console.log('drawn'); }

i suggest code. in code, don't need use settings map:map.

try code

function drawlines(){          var flightpath = new google.maps.polyline({           path: flightplancoordinates,           geodesic: true,           strokecolor: '#ff0000',           strokeopacity: 1.0,           strokeweight: 25,          });         flightpath.setmap(map); }

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...

What is happening when Matlab is starting a "parallel pool"? -

running parallel cpu processes in matlab starts command parpool() according documentation , function: [creates] special job on pool of workers, , [connects] matlab client parallel pool. this function takes bit of time execute, on order of 30 seconds. in other multi-cpu paradigms openmp, parallel execution seems totally transparent -- i've never noticed behavior analogous matlab (granted i'm not experienced parallel programming). so, happening between time parpool() called , when finishes executing? takes long? parallel computing toolbox enables run matlab code in parallel using several different paradigms (e.g. jobs , tasks, parfor , spmd , parfeval , batch processing), , run either locally (parallelised across cores in local machine) or remotely (parallelised across machines in cluster - either 1 own, or 1 in cloud). in of these cases, code run on matlab workers , copies of matlab without interactive desktop. if you're intending run on remo...
