how to Automatically calculate expiry date in backpack laravel? -


i have field name month want when user set month automatic calculate created at month , upload database.

ps - sorry new @ laravel

please see edit:

my store method looks like

<?php  namespace app\http\controllers\admin;  use backpack\crud\app\http\controllers\crudcontroller;   // validation: change requests match own file names if need  form validation use app\http\requests\clientsrequest storerequest; use app\http\requests\clientsrequest updaterequest; use carbon\carbon;   class clientscrudcontroller extends crudcontroller { public function setup() {      $this->crud->setmodel('app\models\clients');     $this->crud->setroute(config('backpack.base.route_prefix') . '/clients');     $this->crud->setentitynamestrings('clients', 'clients');      $this->crud->setfromdb();  }  public function store(storerequest $request) {     // additional operations before save here       $start_day = carbon::parse($request->created_at);     $expiry_day = $start_day->addmonths($request->month);     $request->input($expiry_day);      $redirect_location = parent::storecrud($request);     // additional operations after save here     // use $this->data['entry'] or $this->crud->entry     return $redirect_location; }  public function update(updaterequest $request) {     // additional operations before save here     $redirect_location = parent::updatecrud($request);     // additional operations after save here     // use $this->data['entry'] or $this->crud->entry     return $redirect_location; }

}

assuming mean months ammount ( i.e monthly payment )

you can in store method i.e:

$start_day = carbon::parse($request->created_at); //get carbon instance created_at date $expiry_day = $start_day->addmonths($request->user_selected_months); //add x months created_at date

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 ...
