reactjs - Redirecting to route from Node.JS server doesn't render the next page -


hi have react component renders form this:

<form onsubmit={this.onsubmit}>   <!-- bunch of inputs here --> </form>

where function onsubmit() makes post request /results using axios:

handlesubmit(e) {     var self = this;     e.preventdefault();     const {value1, value 2, ....} = this.state;     axios.post('/results', {         key1 : value1,         key2 : value2,         etc.     }).then(function(response) {       if (errors) {           self.setstate({errors: response.data.errormessage});       }      }).catch(function(error){       console.log(error);     });   }

i have route handler post request in server.js inserts data form database. if there errors it'll send data client, otherwise should redirect results page. handler looks this:

app.post('/results', function(req, res, next) {   const reportexists = report.findone({     attributes: ['caseid'],     where: {caseid : req.body.caseid},   }).then(report => {     if (report) {       console.log("report exists");       res.status(200).send({errormessage : "report has been submitted case id"});     } else {       const report = report.create(         {           // data form         }       ).then(() => {         console.log('record inserted successfully');         var caseid = req.body.caseid;         res.redirect("/results/" + caseid);         next();       })       .catch(err => {         console.log('failed insert record');         res.status(200).send({errormessage: "failed insert record"});       });     }   }); });

i have app.get('/results/:caseid') handler should render appropriate route results page. when record inserted doesn't redirect page, stays on same page form. question is, should redirecting page client or server?

submitting ajax call via client-side javascript gets response server, whatever is. redirect not automatically processed browser, it's ajax response javascript. client-side javascript decide redirect response.

you have couple choices. detect redirect response in client-side javascript , set window.location new location , manually tell browser go new page. or, let browser submit form rather client-side javascript , browser follow redirect response automatically.

also, should not calling next() after call res.redirect(). once you've sent response, should not enable other route handlers execute.

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
