php - Laravel 5.4 - Updating a File record -


i'm pretty new laravel, i'm trying learn of basics. have managed create crud file upload. did created resource controller. store method:

public function store(request $request) {          $this->validate($request, [             'name' => 'required',             'avatar' => 'required|image|mimes:jpeg,png,jpg,gif,svg',             'boat_type' => 'required',             'rooms' => 'required',             'price_per_hour' => 'required',             'price' => 'required',         ]);         $boat = new boat($request->input()) ;             if($file = $request->hasfile('avatar')) {                 $file = $request->file('avatar') ;                 $filename = $file->getclientoriginalname() ;                 $destinationpath = public_path().'/img/boats/avatars/' ;                 $file->move($destinationpath,$filename);                 $boat->avatar = $filename ;             }             $boat->save() ;             return redirect()->route('management.index')                         ->with('success','new boat added!');     }

this method works fine, able upload , store details database , able manipulate in view.

but when try use update method have exact code.. yet when try update post can updated except avatar variable. updates stores in strange format. here update method

public function update(request $request, $id)     {         $this->validate($request, [             'name' => 'required',             'boat_type' => 'required',             'rooms' => 'required',             'price_per_hour' => 'required',             'price' => 'required',         ]);          $boat = boat::find($id);       if($file = $request->hasfile('avatar')) {                 $file = $request->file('avatar') ;                 $filename = $file->getclientoriginalname() ;                 $destinationpath = public_path().'/img/boats/avatars/' ;                 $file->move($destinationpath,$filename);                 $boat->avatar = $filename ;             }             $boat->save() ;         $boat_update = $request->all();         $boat->update($boat_update);         $request->session()->flash('alert-success', 'boat updated!');         return redirect('/management');     }

when edit avatar variable stores in /img/boats/avatars/c:\xampp\tmp\phpfa50.tmp

i'm not sure wrong. appreciated.

  1. $boat->save() ; don't need save before update -> remove it

  2. $boat_update = $request->all(); -> filename not in there

  3. $boat->update($boat_update); fields $fillable? if yes need add new filename array

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
