following code grid. createwbdgriddata triggers database service call , creates table . gridsource json data getting database after converting through json convert function.

$(document).ready(function() { var param ="hole_diameter|4.875_casing_id|5.5_gravel_pack|net_perf_thickness|perf_diameter|perf_gravel_perm_@19k|gravel_beta_factor_@19k|shot_density"; $.when(getwbdgriddatabywell(param)).then(function (data) { }); });  function createwbdgriddata(gridsource) { if (gridsource == undefined) return; console.log(gridsource); $("#grid").kendogrid({     datasource: {         data: gridsource,         schema: {             model: {                 fields: {                     parametername: { type: "string" },                     zone_1: { type: "number" },                     zone_2: { type: "number" },                     zone_3: { type: "number" },                 }             }         },         //  pagesize: 20     },     //height: 550,     //scrollable: true,     //sortable: true,     //filterable: true,     //reorderable: true,     resizable:true,     //pageable: {     // input: true,     //numeric: false     //},     columns: [         { field: "parametername", title: "lucius 01", width: 300 },         { field: "zone_1", title: "zone 1", width: 100 },         { field: "zone_2", title: "zone 2", width: 100 },         { field: "zone_3", title: "zone 3", width: 100 },     ] }); }

controller

var dspstore = "system.sources.db.mssql.dspstore";  function getwbdgriddata(queryname, param) { var vardata = createparamquery(dspstore, queryname, param); callservice(getwbdgriddatacompleted, vardata); }  var getwbdgriddatacompleted = function (result) { if (vardatatype == "json") {     var myitems = $.parsejson(result.getdataitemsresult);     createwbdgriddata(myitems);  } }

service call

function callservice(servicecompleted, vardata) { $.support.cors = true; $.ajax({     context: this,     disablecaching: false,     headers: {         "access-control-allow-origin": '*',         'accept': 'application/json',         'content-type': 'application/json'     },     type: vartype, //get or post or put or delete verb     url: varurl, // location of service     data: vardata, //data sent server     //contenttype: varcontenttype, // content type sent server     datatype: vardatatype, //expected data format server     processdata: varprocessdata, //true or false     success: function (msg) {//on successfull service call         servicecompleted(msg);     },     error: servicefailed// when service call fails }); }

ok , understand there 8 parameters first column , have have has 3 more items user can edit if below . 

$("#grid").kendogrid({     datasource: {       transport: {          read: function (options) {              $.ajax({                 url: "/your controller/your read action",                 datatype: "json",                 cache: false,                 success: function (result) {                   options.success(result);                 },                 error: function (result) {                   options.error(result);                  }                });              },         update: function (options) {              $.ajax({                 url: "/your controller/your update action",                 datatype: "json",                 cache: false,                 data:{model:options.data.models},                 success: function (result) {                   options.success(result);                 },                 error: function (result) {                   options.error(result);                  }                });              },           parametermap: function (options, operation) {             if (operation !== "read" && options.models) {               return { models: kendo.stringify(options.models) };               }             }           },         schema: {           model: {             fields: {              parametername: { type: "string",editable: false },              zone_1: { type: "number",editable: true, validation: { required: true } },              zone_2: { type: "number",editable: true, validation: { required: true } },              zone_3: { type: "number" ,editable: true, validation: { required: true }},                 }             }         },          pagesize: 10     },     resizable:true,     columns: [         { field: "parametername", title: "lucius 01", width: 300 },         { field: "zone_1", title: "zone 1", width: 100 },         { field: "zone_2", title: "zone 2", width: 100 },         { field: "zone_3", title: "zone 3", width: 100 },     ] }); }

use model specify editable , non editable fields , data source data parameter not use unless doing local calls , server calls call function shown above.

and controller action should below : (i assume using mvc)

 [httpget]   public actionresult readgridjson()    {       return json(yourlist, jsonrequestbehavior.allowget);    }   [httpget]       public actionresult updategridjson(yourmodeltype model)        {                 update db , retun updated item          return json(updateitem, jsonrequestbehavior.allowget);        }

hope helps , more infor check out api doc http://docs.telerik.com/kendo-ui/api/web/grid

python - Django-cities exits with "killed" -

i trying install django-cities on server 500mb ram. whenever run: manage.py cities the system exits saying killed. trying run: manage.py cities --import=country --force worked, guessing matter of running out of memory. to bypass, tried refer package local copy of cities' data file. still didn't work. any ideas on how can migrate data without having increase memory on server? based on suggestion comments, solved setting temporary swap file. if unfamiliar it, can follow these steps: set swap file touch /var/swap.img chmod 600 /var/swap.img set swap file size cd /var dd if=/dev/zero of=/var/swap.img bs=1024k count=1000 this create 1gb swap file. prepare disk image mkswap /var/swap.img activate swap memory swapon /var/swap.img once done, can turn off swap image: swapoff /var/swap.img more information on virtual memory , swap files can found here: https://www.digitalocean.com/community/tutorials/how-to-configure-virtual-me
