angular - How to perform hide and show buttons in listview items without removing DOM in angular2 nativescript -


i need perform hide , show buttons in listview items programatically based on condition.

below have tried *ngif condition. removing dom entirely.so shows secondvisible layout buttons entirely.

html file:

// inside listview ng-template :   <button *ngif="firstvisible" row="0" col="2" text="first"> </button>   <stacklayout *ngif="secondvisible" row="0" col="2">     <button text="second" > </button>     <button text="group"  </button>  </stacklayout>

ts file:

  if(avail == true){              this.firstvisible = true;             this.secondvisible = false;             } else {              this.firstvisible = false;             this.secondvisible = true;             }

is there other way perform hide , show button programatically without removing dom in listview except *ngif condition. 

<button [hidden]="firstvisible" row="0" col="2" text="first"> </button>

using hidden property hide dom , not delete entirely, if want show use:

<button [hidden]="!firstvisible" row="0" col="2" text="first"> </button>

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
