I have a JSON file and I am trying to calculate the JSON file key based on the value and reformating it. My JSON file looks like below:
data=[
{
pet:'Cat',
fruit:'Apple',
fish:'Hilsha'
},
{
pet:'Dog',
fish:'Carp'
},
{
pet:'Cat',
fruit:'Orange',
fish:'Lobster'
}
];
I do like to calculate and formate it like below:
data=[
{
label:'Pet',
total:3,
list:[
{
name:'Cat',
value: 2,
},
{
name:'Dog',
value: 1,
}
]
},
{
label:'Fruit',
total:2,
list:[
{
name:'Apple',
value: 1,
},
{
name:'Orange',
value: 1,
}
]
},
{
label:'Fish',
total:3,
list:[
{
name:'Hilsha',
value: 1,
},
{
name:'Carp',
value: 1,
},
{
name:'Lobster',
value: 1,
}
]
},
];
If anybody can help me, it will be very help for me and will save a day.
I have fixed this task myself. If I have any wrong, you can put your comment fill-free :)
``
ngOnInit(): void {
this.dataService.$data.subscribe(data => {
// Create new object and calculation according to category
let petObj: any = {}
let fruitObj: any = {}
let fishObj: any = {}
data.forEach((el: any) => {
if (el.pet != undefined) {
petObj[el.pet] = (petObj[el.pet] || 0) + 1;
}
if (el.fruit != undefined) {
fruitObj[el.fruit] = (fruitObj[el.fruit] || 0) + 1;
}
if (el.fish != undefined) {
fishObj[el.fish] = (fishObj[el.fish] || 0) + 1;
}
});
// Create list according to category
let pet_list: any = [];
let fruit_list: any = [];
let fish_list: any = [];
for (var key in petObj) {
let pet = {
label: key,
value: petObj[key]
}
pet_list.push(pet)
}
for (var key in fruitObj) {
let fruit = {
label: key,
value: fruitObj[key]
}
fruit_list.push(fruit)
}
for (var key in fishObj) {
let fish = {
label: key,
value: fishObj[key]
}
fish_list.push(fish)
}
// Calculate total sum according to category
var totalPet = pet_list.map((res: any) => res.value).reduce((a: any, b: any) => a + b);
var totalFruit = fruit_list.map((res: any) => res.value).reduce((a: any, b: any) => a + b);
var totalFish = fish_list.map((res: any) => res.value).reduce((a: any, b: any) => a + b);
// Rearrange the JSON
this.rearrangeData = [
{
label: 'Pet',
total: totalPet,
list: pet_list
},
{
label: 'Fruit',
total: totalFruit,
list: fruit_list
},
{
label: 'Fish',
total: totalFish,
list: fish_list
}
]
console.log(this.rearrangeData)
// End rearrange the JSON
});
}

You can simplify your function. Take a look this one
group(oldData) {
const data = []; //declare an empty array
oldData.forEach((x) => {
//x will be {pet: 'Cat',fruit: 'Apple',fish: 'Hilsha'},
// {pet: 'Dog',fish: 'Carp'}
// ...
Object.keys(x).forEach((key) => {
//key will be 'pet','fruit',...
const item = data.find((d) => d.label == key); //search in the "data array"
if (item) { //if find it
item.total++; //add 1 to the property total of the element find it
// and search in the item.list the 'Cat'
const list = item.list.find((l) => l.name == x[key]);
//if find it add 1 to the property value of the list
if (list)
list.value++;
else
//if not, add to the list
//an object with property "name" and "value" equal 1
item.list.push({ name: x[key], value: 1 });
} else
//if the element is not in the "array data"
//add an object with properties label, total and list
//see that list is an array with an unique element
data.push({
label: key,
total: 1,
list: [{ name: x[key], value: 1 }],
});
});
});
return data;
}
You can use like
this.dataService.$data.subscribe(data => {
this.rearrangeData=this.group(data)
}
NOTE: this function the labels are 'pet','fruit' and 'fish' not 'Pet', 'Fruit' and 'Fish'
Did you try reading the text leading up to this exercise? That'd be my first approach. After that, I'd use reduce. You can do pretty much anything with reduce.
We are working with a 3rd party grid (telerik kendo) that has paging/sorting/filtering built in. It will send the requests in a certain way when making the GET call and I'm trying to determine if there is a way to translate these requests to AutoQuery friendly requests.
Query string params
Sort Pattern:
sort[{0}][field] and sort[{0}][dir]
Filtering:
filter[filters][{0}][field]
filter[filters][{0}][operator]
filter[filters][{0}][value]
So this which is populated in the querystring:
filter[filters][0][field]
filter[filters][0][operator]
filter[filters][0][value]
would need to be translated to.
FieldName=1 // filter[filters][0][field]+filter[filters][0][operator]+filter[filters][0][value] in a nutshell (not exactly true)
Should I manipulate the querystring object in a plugin by removing the filters (or just adding the ones I need) ? Is there a better option here?
I'm not sure there is a clean way to do this on the kendo side either.
I will explain the two routes I'm going down, I hope to see a better answer.
First, I tried to modify the querystring in a request filter, but could not. I ended up having to run the autoqueries manually by getting the params and modifying them before calling AutoQuery.Execute. Something like this:
var requestparams = Request.ToAutoQueryParams();
var q = AutoQueryDb.CreateQuery(requestobject, requestparams);
AutoQueryDb.Execute(requestobject, q);
I wish there was a more global way to do this. The extension method just loops over all the querystring params and adds the ones that I need.
After doing the above work, I wasn't very happy with the result so I investigated doing it differently and ended up with the following:
Register the Kendo grid filter operations to their equivalent Service Stack auto query ones:
var aq = new AutoQueryFeature { MaxLimit = 100, EnableAutoQueryViewer=true };
aq.ImplicitConventions.Add("%neq", aq.ImplicitConventions["%NotEqualTo"]);
aq.ImplicitConventions.Add("%eq", "{Field} = {Value}");
Next, on the grid's read operation, we need to reformat the the querystring:
read: {
url: "/api/stuff?format=json&isGrid=true",
data: function (options) {
if (options.sort && options.sort.length > 0) {
options.OrderBy = (options.sort[0].dir == "desc" ? "-" : "") + options.sort[0].field;
}
if (options.filter && options.filter.filters.length > 0) {
for (var i = 0; i < options.filter.filters.length; i++) {
var f = options.filter.filters[i];
console.log(f);
options[f.field + f.operator] = f.value;
}
}
}
Now, the grid will send the operations in a Autoquery friendly manner.
I created an AutoQueryDataSource ts class that you may or may not find useful.
It's usage is along the lines of:
this.gridDataSource = AutoQueryKendoDataSource.getDefaultInstance<dtos.QueryDbSubclass, dtos.ListDefinition>('/api/autoQueryRoute', { orderByDesc: 'createdOn' });
export default class AutoQueryKendoDataSource<queryT extends dtos.QueryDb_1<T>, T> extends kendo.data.DataSource {
private constructor(options: kendo.data.DataSourceOptions = {}, public route?: string, public request?: queryT) {
super(options)
}
defer: ng.IDeferred<any>;
static exportToExcel(columns: kendo.ui.GridColumn[], dataSource: kendo.data.DataSource, filename: string) {
let rows = [{ cells: columns.map(d => { return { value: d.field }; }) }];
dataSource.fetch(function () {
var data = this.data();
for (var i = 0; i < data.length; i++) {
//push single row for every record
rows.push({
cells: _.map(columns, d => { return { value: data[i][d.field] } })
})
}
var workbook = new kendo.ooxml.Workbook({
sheets: [
{
columns: _.map(columns, d => { return { autoWidth: true } }),
// Title of the sheet
title: filename,
// Rows of the sheet
rows: rows
}
]
});
//save the file as Excel file with extension xlsx
kendo.saveAs({ dataURI: workbook.toDataURL(), fileName: filename });
})
}
static getDefaultInstance<queryT extends dtos.QueryDb_1<T>, T>(route: string, request: queryT, $q?: ng.IQService, model?: any) {
let sortInfo: {
orderBy?: string,
orderByDesc?: string,
skip?: number
} = {
};
let opts = {

data.sort.forEach((s: any) => {
if (s.field.indexOf('.') > -1) {
var arr = _.split(s.field, '.')
s.field = arr[arr.length - 1];
}
})
}//for autoquery to work, need only field names not entity names.
sortInfo = {
orderByDesc: _.join(_.map(_.filter(data.sort, (s: any) => s.dir == 'desc'), 'field'), ','),
orderBy: _.join(_.map(_.filter(data.sort, (s: any) => s.dir == 'asc'), 'field'), ','),

There is no build in method to export jqgrid data to pdf. You have to use third party tools( I personally like iTextSharp which can be downloaded from Here . You have to create action method for printing the grid data in your controller.
Here is also another one example one guy made.
Here is also another example in trirand. If you see the source code they are using iTextHsarp.
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;

// This is the default action for the View. Use it to setup your grid Model.
public ActionResult ExportPDF()
{
// Get the model (setup) of the grid defined in the /Models folder.
var gridModel = new OrdersJqGridModel();
var ordersGrid = gridModel.OrdersGrid;
// Setting the DataUrl to an action (method) in the controller is required.
// This action will return the data needed by the grid
ordersGrid.DataUrl = Url.Action("PDFGrid_DataRequested");
// customize the default Orders grid model with custom settings
// NOTE: you need to call this method in the action that fetches the data as well,
// so that the models match
SetPDFExportGrid(ordersGrid);
// Pass the custmomized grid model to the View
return View(gridModel);
}
// This method is called when the grid requests data

I have a project in which I'm using the KendoUI Grid using the server to get the data instead of locally.
I'm not sure what the JSON response should be from my server to get grouping to work however. My goal is when the user drags a column to the grouping header that I know what kind of JSON response to give back so the GRID groups by that column and any other columns that might be added to that header.
Given the image above, how do I create a JSON response to fulfill it (so its showing what its supposed to grouped)? I get I have to do this on my own on the server but not sure how JSON needs to be formated. Furthermore if I want to show a 'count' field next to the groups when they are created so I know how many items are in each group (which I believe is the aggregate?)
My current grid codes looks like the following:
<div id="grid" style="height:100%;"></div>
<script>
$(window).on("resize", function() {
kendo.resize($("#grid"));
});
var crudServiceBaseUrl = "/api",
dataSource = new kendo.data.DataSource({

The current JSON it creates looks like this.
JSON
{"itemCount":"7","items":[{"id":"1","name":"Joe","phone":"(714)475-8651","email":"Joe#whatever.com"},{"id":"2","name":"Rachel","phone":"(563)812-4184","email":"rachel#yahoo.com"},{"id":"3","name":"John","phone":"(563)812-4184","email":"John#yahoo.com"},{"id":"4","name":"Richard","phone":"(563)812-4184","email":"Richard#yahoo.com"},{"id":"5","name":"Sister","phone":"(563)812-4184","email":"Sister#yahoo.com"},{"id":"6","name":"Brother","phone":"(563)812-4184","email":"Brother#yahoo.com"},{"id":"7","name":"Sibling","phone":"(563)812-4184","email":"Sibling#yahoo.com"}]}
I found an article here that looks close to what I want just hard to understand. This might also help.
I created JSFiddle that can be played around with, just needs to be supplied valid data.
Update
I got server paging to work! The first major change is on the transport for the datasource you have to change the parameterMap to send json so you can access what its trying to tell your server to change.
dataSource = new kendo.data.DataSource({
transport: {
read: {
url: crudServiceBaseUrl + "/companies",
dataType: "json",
type: "POST"
},
update: {
url: crudServiceBaseUrl + "/companies/update",
dataType: "json",
type: "POST"
},
destroy: {
url: crudServiceBaseUrl + "/companies/destroy",
dataType: "json",
type: "POST"
},
create: {
url: crudServiceBaseUrl + "/companies/create",
dataType: "json",
type: "POST"
},
parameterMap: function(options, operation) {
return kendo.stringify(options);
}
},
My datasource looks like above, but you could adjust to your needs. Next my php file below.
PHP
/companies
/**
* #Route("/api/companies", name="api_companies_read")
*/
public function apiCompaniesReadAction(Request $request)
{
$request_body = file_get_contents('php://input');
$json = json_decode($request_body);
//Based on the JSON Payload response adjust the search in the database
if($json){
$page = $json->page;
$pageSize = $json->pageSize;
$skip = $json->skip;
$take = $json->take;
}else{
$page = 1;
$pageSize = 20;
$skip = 1;
$take = 1;
}
$repository = $this->getDoctrine()->getRepository('AppBundle:Company');
/*
findBy(
array $criteria,
array $orderBy = null,
integer|null $limit = null,
integer|null $offset = null
)
*/
$company_total = $repository->findAll();
$company_records = $repository->findBy(array(),array(),$pageSize,($page-1)*$pageSize);
$data["total"] = count($company_total);
foreach($company_records as $company){
$temp["id"] = $company->getId();
$temp["name"] = $company->getName();
$temp["phone"] = $company->getPhone();
$temp["email"] = $company->getEmail();
$data["data"][] = $temp;
}
//converts data to JSON
return new JsonResponse($data);
}
Please remember the above is a Symfony 3.0 php implementation using annotations to set the route. The important part in that code is.
$request_body = file_get_contents('php://input');
$json = json_decode($request_body);
//Based on the JSON Payload response adjust the search in the database
if($json){
$page = $json->page;
$pageSize = $json->pageSize;
$skip = $json->skip;
$take = $json->take;
}else{
$page = 1;
$pageSize = 20;
$skip = 1;
$take = 1;
}
The file_get_contents('php://input'); gets the javascript object that the KendoUI control sends back.
UPDATE # 3 Got Server Sorting Working!
Below is an example implementaiton using Symfony 3.0 and Doctrine to do Server Sorting!
PHP
/**
* #Route("/api/companies", name="api_companies_read")
*/
public function apiCompaniesReadAction(Request $request)
{
$request_body = file_get_contents('php://input');
$json = json_decode($request_body);
//print_r($json);
//default parameters in case of error.
$page = 1;
$pageSize = 20;
$skip = 1;
$take = 1;
$sort = array();
//Based on the JSON Payload response adjust the search in the database
if(isset($json)){
$page = $json->page;
$pageSize = $json->pageSize;
$skip = $json->skip;
$take = $json->take;
if(isset($json->sort)){
//"sort":[{"field":"name","dir":"asc"}]}:
foreach($json->sort as $sortObj){
$sort[$sortObj->field] = $sortObj->dir;
}
}
}
$repository = $this->getDoctrine()->getRepository('AppBundle:Company');
/*
findBy(
array $criteria,
array $orderBy = null,
integer|null $limit = null,
integer|null $offset = null
)
*/
$company_total = $repository->findAll();
$company_records = $repository->findBy(array(),$sort,$pageSize,($page-1)*$pageSize);
$data["total"] = count($company_total);
foreach($company_records as $company){
$temp["id"] = $company->getId();
$temp["name"] = $company->getName();
$temp["phone"] = $company->getPhone();
$temp["email"] = $company->getEmail();
$data["data"][] = $temp;
}
//converts data to JSON
return new JsonResponse($data);
}
That first link is spot on. I had to export data from a grid to pdf and excel adhering to the grid grouping. I finally figured out the semantics. The grid has columns and data objects which you can get through grid calls. The data object holds the grouping information. Here is the processing operation.
In a nutshell, you have to recursively iterate the data object tpo determine the grouping. For each element in the data you need to inspect if the data[x].value exists. If it exists then it is a group object with child data. If it does not exists then you use the normal data[row][column].field to get to the child data. The trick here is to call a recurisive function for each point where dat[0].value has data and finally process the data[row][column] on the unwind.
Below is a js function you can use to inspect the Grid's json dta. I would add a group or two to your grid and see the difference between the data with/without grouping applied and that should be what you need to add to your data....I think you pretty much add data as data={[[],[]]}unless it is a group, then it is data={[value='groupName',{[],[]}]}.
function showData(gridName) {
var grid = $('#' + gridName).data('kendoGrid');
var data = grid.dataSource.data().toJSON();
console.log(data);
}
i'm having trouble trying to figure out how this is happening. i'm using Extjs and AJAX with JsonStore from my callback my page in ASP call the database and return some fields in this fields there is a Date and this date return the proper date ex.: "date_creat_post": "29\u002F04\u002F2011"...
Now once i look at my output from this in my page in a datagrid i'm getting the following:
04/05/2013 <----> the date it return in the callback is 04/05/2011
06/05/2012 <----> the date it return in the callback is 06/05/2010
07/04/2012 <----> the date it return in the callback is 07/04/2010
I looked all threw my code to see if they're is a place where i am adding 1 year to the date.
but can't find it. i have been trying now for at least 2 days to figure this out.

Thanks in advance i hope some on on the wicked web can help me....
cheers.
so after trying many solution giving to be i came to this has problem
finally the the date example after many attemps to format and inserting in my msSQL database
this problem is the problem : 13\09\2011 (d/m/Y) becomes this 09/01/2012 (d/m/Y) so for some reason the month 13 is being added to the month so say the 13 month doesn't exist so the date will go to 09/01/2012....
after looking again it's the format that doesn't seem ok so i changed it de (m/d/Y) and now im getting a sql error when i hit 13 day on my datefield in (extjs).
"The conversion of a varchar data type to a datetime data type resulted in an out-of-range value."
and on and on does anyone have any ideas now ????
Instead of using the built in Ext.util.Format.dateRenderer, you could try creating one of your own that parses the Date as desired.
ataIndex: 'date_creat_post',
header: 'Date Created',
renderer: daterenderer
And then a function for your daterenderer:
function dateRenderer(value, id, r) {
var myDate = r.data['date_creat_post'];
// do some things here to strip out the date and make it into a happy format
var d = new Date(myDate);
return d.format('d/m/Y');
}
