html5 - Router Outlet displays more than 1 component -


i having trouble seting navigation of app. reason router outlet have set keeps displaying components after clicking routerlink component, show them on after other , if keep clicking de links tables(thats components are) displayed 1 more time on view.

that's sidenav:

<ul id="sidenav"  class="side-nav">   <li> <div class="square " id="logocontainer">   <img src="../../assets/img/{{brand}}logo.jpg" id="logo" class="backimg"> </div> </li> <li><a routerlink="/admregiones">inicio<i class="material-icons">home</i></a> </li> <ul class="collapsible collapsible-accordion"> <li>   <a class="collapsible-header">regiones<i class="material-icons" style="padding-left: 15px">terrain</i></a>   <div class="collapsible-body">     <ul>       <li><a routerlink="/admregiones" class="waves-effect waves-blue"><i class="material-icons right" style="padding-left: 10px">add_location</i>  administrar regiones  </a></li>     </ul>   </div> </li> </ul> <li class="no-padding"> <ul class="collapsible collapsible-accordion">   <li>     <a class="collapsible-header">locaciones<i class="material-icons" style="padding-left: 15px">map</i></a>     <div class="collapsible-body">       <ul>         <li><a routerlink="/buscarlocacion"  class="waves-effect waves-blue"><i class="material-icons right" style="padding-left: 10px">location_searching</i>ir locación </a></li>         <li><a routerlink="/admlocaciones"  class="waves-effect waves-blue"><i class="material-icons right" style="padding-left: 10px">add_location</i>  administrar locaciones  </a></li>       </ul>     </div>   </li> </ul> </li> </ul>

this routes:

routermodule.forroot([   {     path: 'admlocaciones',     component: admlocacionescomponent   },   {     path: 'buscarlocacion',     component: buscarlocacioncomponent   },   {     path: 'admregiones',     component: admregionescomponent   } ])

here component display(both admregiones , admlocaciones practically same):

<div class="container col s8"style="padding-top: 4%;"> <a href="#modalnuevalocacion" class="waves-effect waves-light btn modal-trigger" (click)="openmodal(); exportedinitialize();">modal</a>  <table class="highlight striped center" id="tablalocaciones" onload="loadtablalocaciones()"> <hr> <thead> <tr>   <th>id</th>   <th>nombre</th>   <th>región</th>   <th>editar</th>   <th>eliminar</th> </tr> </thead> <tbody id="locacionesbody"> </tbody> </table> </div>

and app-component template:

<app-header></app-header>  <div id="body"> <router-outlet></router-outlet> </div> <app-locacion></app-locacion> <app-side-nav></app-side-nav>

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 ...
