-

i following following tutorial:

http://mrhawley.com/

problem doesn't finish. however, point goes best tutorial around developing extjs app sencha cmd , using codeigniter backend framework.

i decided try fill in gaps , guess @ going. got create /read , update methods working nicely can't seem delete work.

here extjs store:

ext.define('bugtracker.store.user.userlist', { extend: 'ext.data.store', requires: [     'bugtracker.model.user.userlist' ], constructor: function(cfg) {     var me = this;     cfg = cfg || {};     me.callparent([ext.apply({             model: 'bugtracker.model.user.userlist',             autoload: false,             remotefilter: false,             remotesort: false,             pagesize: 5,             sorters: {                 property: 'username',                 direction: 'asc'             },             proxy: {                 type: 'rest',                 actionmethods: {                     create: 'post',                     read: 'get',                     update: 'post',                     destroy: 'post'                 },                 api: {                     create: 'index.php/user/new_user',                     read: 'index.php/user/get_users',                     update: 'index.php/user/update_user',                     destroy: 'index.php/user/delete_user'                 },                 reader: {                     type: 'json',                     root: 'data'                 },                 writer: {                     type: 'json',                     writeallfields: false,                     allowsingle: false,                     encode: true,                     root: 'data'                 }             }         }, cfg)]); } });

and here extjs controller: 

ext.define('bugtracker.controller.user.useradmin', { extend: 'ext.app.controller', refs: [     {         ref:'userform',         selector:'userform'     } ], init: function(){     this.control({         'maintoolbar button[action=openuseradminpanel]':{             click:function(){                 var panel =  ext.widget('useradminpanel');                 panel.show();             }         },         'userform button[action=saveuser]':{             click:function(button){                 var form = button.up('form').getform(),                     values = form.getvalues(),                     store = ext.getstore('user.userlist');                  if (form.isvalid()) {                     switch (button.gettext()){                         case 'save':                             store.create(values);                             break;                         case 'update':                             var record = form.getrecord();                             record.set(values);                             store.update();                             button.settext('save');                     }                     this.loaduserlist();                     this.resetform(form);                 }             }         },         'userform button[action=deleteuser]':{             click:function(button){                 var form = button.up('form').getform(),                     values = form.getvalues(),                     store = ext.getstore('user.userlist');                 if (form.isvalid()) {                     ext.messagebox.confirm('delete',                         'are sure want delete user "' + values.username + '"?',                         function(button){                             switch (button) {                                 case 'yes':                                     store.destroy(values.id);                                     break;                                 default:                                     break;                             }                         });                     this.loaduserlist();                 }                 this.resetform(form);             }         },         'userlist':{             afterrender:this.loaduserlist,              cellclick:function(grid,td,cellindex,record,tr,rowindex,e,eopts){                 var form = this.getuserform(),                     button = form.down('button[action=saveuser]');                 form.loadrecord(record);                 button.settext('update');             }         }     }); }, resetform:function(form){     form._record = null;     form.reset(); }, loaduserlist:function(){     var store = ext.getstore('user.userlist');     store.removeall();     store.load(); } });

as can see when click on delete button calls store.destroy , sends post call index.php/users/delete_user. however, sending empty array. have dumped out values.id , comes right id. have tried sending entire array. no matter sends empty array.

so dumping out 'data' key on backend determine being sent. coming empty array. however, noticed when called store.destroy(values) 'id' sent not part of data key. proceeded account , deletion works fine.

the reason confused because set reader , writer of proxy have root of "data". however, guess deleting items not fall under either of these , therefore not put id inside of 'data' root. thank @stormdrain giving me hint towards issue!

java - Copying object fields -

-
what best way of copying classes when need have 2 independent variables? have simple class: public class myclass { boolean = false; string b= "not empty"; } do need make method : assign(myclass data ) { a= data.a; b= data.b; } is there automatic method copy (duplicate) objects in java? do need make method : pretty close. instead of making method, should make constructor. such constructors called copy constructor , , create them this: myclass(myclass data) { = data.a; b = data.b; } and create copy of instance, use constructor this: myclass obj1 = new myclass(); myclass obj2 = new myclass(obj1); copy constructor can tedious : using copy constructor create deep-copy can tedious, when class has mutable fields. in case, assignment create copy of reference, , not object itself. have create copy of fields (if want deep copy). can go recursive. a better way create deep copy serialize , deserialize object. why not use clone()? ...

c++ - Clear the memory after returning a vector in a function -

-
i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.
