javascript - How to filter json based on a query dynamically generated? -


i want filter json object using js angular project. json structure this:

{  "docs": [ {   "firstname": "",   "lastname": "",   "birthdate": "",   "city": "",   "country": "" }, {   "firstname": "",   "lastname": "",   "birthdate": "",   "city": "",   "country": "" } ] }

the query builder similar angular-query-builder

the query like:

(firstname = tom or (firstname = jerry , lastname = jack))

based on query js function should filter json object , console resulting json .

you can use custom filter (if don't want use query builder) filter out values based on firstname , lastname

function myctrl($scope){      $scope.people = {   "docs": [  {    "firstname": "tom",    "lastname": "larry",    "birthdate": "",    "city": "",    "country": ""  },  {    "firstname": "jerry",    "lastname": "jack",    "birthdate": "",    "city": "",    "country": ""  },  {    "firstname": "tom",    "lastname": "thomas",    "birthdate": "",    "city": "",    "country": ""  },  {    "firstname": "jerry",    "lastname": "gaer",    "birthdate": "",    "city": "",    "country": ""  }  ]  }      $scope.myfilter = function(item){          if((item.firstname == "tom")||(item.firstname == "jerry"&&item.lastname == "jack")){              return true;          }      };  }
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>  <div ng-app>      <div ng-controller="myctrl">         <ul>             <li ng-repeat="person in people.docs | filter:myfilter">  {{person.firstname}} {{person.lastname}}             </li>         </ul>      </div>  </div>

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 ...
