vue.js - How can I get data inside of Vue from database like config or smth> - 


var app = new vue({     el: '#app',      data: {         positions: []     },      created() {          axios.get('/config').then(function(response) {             this.$set(this.positions, "positions", response.data[0].dragedpositions);         });          console.log(this.positions.positions);     }  });

i have configs app in database , want use them inside of vue instance (here positions of elements). when im getting "this.positions.positions" im getting empty string.. how can that?

sounds want load config first , bootstrap application after that. use propsdata this:

axios.get('/config').then(function(response) {   new vue({     el: '#app',     props: ['positions'],     propsdata: {       positions: response.data[0].dragedpositions     },     created() {       console.log(this.positions);     }   }); });

i created little demo :)

const axios = {get () {    return promise.resolve({data: [{dragedpositions: [1,2]}]})  }}    axios.get("/config").then(function(response) {    new vue({      el: "#app",      props: ['positions'],      propsdata: {        positions: response.data[0].dragedpositions      },      created() {        console.log('created hook', this.positions);      }    });  });
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.3.4/vue.min.js"></script>    <pre id="app">positions = {{ positions }}</pre>

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 ...
