javascript - How to pass props to all routes in vue.js? -


i want pass base_url components. app.js like:

<template> <router-view></router-view> </template>  <script> import addjoke './components/addjoke.vue' import showjokesall './components/showjokesall.vue'  export default {    components: {     'add-joke': addjoke,     'show-jokes-all': showjokesall   },    data () {     return {         base_url : 'http://127.0.0.1:8090'            }   } } </script>  <style>  </style>

and routes.js:

import showjokesall './components/showjokesall.vue'; import addjoke './components/addjoke.vue';  export default [   {path:'/', component: showjokesall, props: {base_url: 'http://127.0.0.1:8090'} },   {path:'/add', component: addjoke, props: {base_url: 'http://127.0.0.1:8090'}  }   ]

and in showjokesall component have:

<script> import axios 'axios';      export default {         name: 'showjokesall',         props: ['base_url'],       data () {         return {             jokes:[]                     }       },       methods: {       },        created() {         axios.get( base_url + '/api/jokes').then( response => this.jokes = response.data);      } } </script>

but components not received base_url.

[vue warn]: error in created hook: "referenceerror: base_url not defined"

how can fix this?

to access prop define props: ['base_url'], use this.base_url:

axios.get( this.base_url + '/api/jokes').then(/*...*/)

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 ...
