ExtJS: How to use alias/xtype to refer to other components -


i new in extjs , having in this fiddle simple application (which still not working) bind data store grid view. store like: 

ext.define('extapp.store.bookstore',{         extend: 'ext.data.store',         model: 'extapp.model.bookmodel',         fields: ['title', 'author', 'price', 'qty'],         data: [....some data.....] });

and call store inside of view dont know how that, view looks like: 

ext.define('extapp.view.bookview',{         extend: 'ext.grid.panel',         alias: 'widget.booklist',         title: 'book list',         store: **what should put here** });

one way found in internet can create store variable , put variable inside of view, like: 

var bookstore = ext.create('extapp.store.bookstore'); bookstore.load();

and inside view: store: bookstore .

but ask how can use alias or xtype in case instead of creating store variable? tried putting inside of store: alias: 'store.bookstore' , inside view called: store: 'bookstore', didnt work. tried using: xtype: 'store.bookstore' , store: 'bookstore', still same result, not working.

and can please explain me difference between alias , xtype, in case should use alias, case should use xtype? thank you!

add storeid in store config , set stores:[yourstore] in app.js

sencha fiddle

extjs alias vs xtype

ext.onready(function(){      ext.define('extapp.model.bookmodel',{         extend: 'ext.data.model',         fields: [             {name: 'title', type: 'string'},             {name: 'author', type: 'string'},             {name: 'price', type: 'int'},             {name: 'qty', type: 'int'}         ]     });      ext.define('extapp.store.bookstore',{         extend: 'ext.data.store',         alias: 'store.bookstore',         storeid :'bookstore',         model: 'extapp.model.bookmodel',         fields: ['title', 'author', 'price', 'qty'],         data: [             { title: 'jdbc, servlet , jsp',              author: 'santosh kumar', price: 300, qty : 12000 },             { title: 'head first java',              author: 'kathy sierra', price: 550, qty : 2500 },             { title: 'java scjp certification',              author: 'khalid mughal', price: 650, qty : 5500 },             { title: 'spring , hinernate',              author: 'santosh kumar', price: 350, qty : 2500 },             { title: 'mastering c++',              author: 'k. r. venugopal', price: 400, qty : 1200 }         ]     });       ext.define('extapp.view.bookview',{         extend: 'ext.grid.panel',         alias: 'widget.booklist',         title: 'book list',         store: 'bookstore',         initcomponent: function(){             this.tbar = [{                 text: 'add book',                 action: 'add',                 iconcls: 'book-add'             }];              this.columns = [                 {                     header: 'title',                     dataindex: 'title',                     flex: 1                 },                 {                     header: 'author',                     dataindex: 'author'                 },                 {                     header: 'price',                     dataindex: 'price',                     width: 60                 },                 {                     header: 'quantity',                     dataindex: 'qty',                     width: 80                 }             ];             this.callparent(arguments);         }     });        ext.application({         name:'extapp',         stores: [         'extapp.store.bookstore'     ],         launch: function(){             ext.widget('booklist',{                 width: 800,                 height: 300,                 renderto: ext.getbody()             });         }     }); })

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 ...
