-

i'm using kendo grid, server side filtering , server side sorting. in data source transport read method field null. suggestions?

this code initializing grid:

var griddatasource = new kendo.data.datasource({             transport: {                 read: {                     url: '@url.action("read", "gridmodule")',                     type: 'post',                     contenttype: 'application/json'                 },                 parametermap: function (options) {                     options.assignmentfilters = assignmentfilters;                     return json.stringify(options);                 }             },             pagesize: 20,             serverpaging: true,             serversorting: true,             serverfiltering: true,             schema: {                 model: {                     fields: {                         lastsurveydate: { type: "date" },                         lastnotedate: { type: "date" }                     }                 },                 data: "data",                 total: "totalrows"             }         });          var $grid = $('#gridassignments');          if (e.firstload) {             $grid.kendogrid({                 scrollable: true,                  pageable: {                     refresh: true,                     pagesizes: [20, 50, 100, 500, 1000],                     buttoncount: 12,                     messages: {                         display: "showing {0}-{1} {2} provider contacts",                         empty: "no contacts match filter criteria",                         itemsperpage: "contacts per page"                     }                 },                 reorderable: true,                 navigatable: true,                 change: gridonchange,                 databound: gridondatabound,                 datasource: griddatasource,                 columnreorder: gridcolumnreorder,                  columnhide: gridcolumnhide,                 columnresize: gridcolumnresize,                 columnshow: gridcolumnshow,                 columnmenu: {                     sortable: false,                     messages: {                         columns: "choose columns",                         filter: "filter",                        }                 },                 resizable: true,                 height: '720px',                 filterable: {                     extra: false,                     operators: {                         string: {                             contains: "contains",                         },                         date: {                             lt: "is before",                              gt: "is after",                             equal: "on"                         }                     }                 },                 selectable: "row",                 sortable: {                     mode: "single",                     allowunsort: true                 },                 columns: [ @html.raw(model.gridcolumns.columns) ]         });         } else {             $grid.data('kendogrid').setdatasource(griddatasource);         }

for runs same problem...

in case code worked fine until added 2 fields schema.model.fields. reason field in read method of grid module null. default fields treated strings when added 2 new properties no default used.

i had add grid's fields

            schema: {                 model: {                     fields: {                         lastsurveydate: { type: "date" },                         lastnotedate: { type: "date" },                         firstname: { type: "string" },                         lastname: { type: "string" },                         hasneweval: { },                         hascommitmentstoget: { },                         onprioritylist: { type: "string" },                         hasproductsbelowminimum: { type: "hasproductsbelowminimum" },                         points: {},                         title: { type: "string" },                         provider: { type: "string" },                         phone: { type: "string" },                         timezone: { type: "string" },                         touches: { type: "string" },                         lastnotetext: { type: "string" },                         verbalaging: { type: "string" }                     }                 },

that worked me.

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.
