I have the below data containing list of roomtypes.Each room type can have multiple rates and I want to show it in a data table but I am only able to show the roomtypes values.

The table should have three colums ie. Room Type, Availability, Rate
Under the Rate column i want to create another datatable that can show Rate type, Availability,Price.

The no. of rates available for a particular roomtype is not static.Hence I need to create a dynamic table.The table should look like this.
LWC template:
       
 <div style="height: 125px;">
                <lightning-datatable
                        key-field="id"
                        data={roomTypeList}
                        show-row-number-column
                        row-number-offset={rowOffset}
                        hide-checkbox-column
                        columns={columnList}>
                </lightning-datatable>
            </div>

.js file:

const columnList = [
    {label: 'Room Type', fieldName: 'title'},
    {label: 'Availability', fieldName: 'availableroom'},
    {label: 'Rates', fieldName: 'rates'}
];

searchroom({hotelid:this.hotelid,cindate:this.checkindate,coutdate:this.checkoutdate})
            .then(result =>{
                console.log(result);
                console.log('============result '+JSON.stringify(result));
                this.roomTypeList = result;
            })

result value::::::

Below is the json data i am recieving.I want to get the value of datetime,accesskey and accesssecret in apex
{"hotelogix":{"version":"1.0","datetime":"2019-11-13T05:40:14","response":{"status":{"code":0,"message":"success"},"accesskey":"0vi1yR7ssx4IMrw","accesssecret":"rbgTdw6kfpE8ZQV"},"request":{"method":"wsauth","key":"5151BE0BE4A9B667C07"}}}
I have used the online Hmac generator and tested an API. Now I want to do the same thing using apex code.

I am not getting the success method by using the mac code generated using the method "Crypto.generateMac()".

I am generating the mac code using the method generateHmacSHA1Signature and calling the endpoint url using the mac generated earlier.

Getting the response as invalid signature.
public class HMACGenearatorHandler {
     public void createJson(){
         String jsonString; // create json here
         String json = '{"hotel":{"version":"1.0","datetime":"2019-11-12T08:09:59","request":{"method":"wsauth","key":"5151BE0BE4A9B667C07C727602C2EF4589658741"}}}';
         String sText= json.replaceAll( '\\s+', '');
         String strMd5= EncodingUtil.base64Encode (Crypto.generateDigest('MD5', Blob.valueOf(sText)));
         sendRequest(sText);
      generateHmacSHA1Signature(sText,'8B434FB19209EEE32002073C8680464785236985');
     } 
    
    @future (callout=true)
	public static void sendRequest(String jsonString){
        HttpRequest req = new HttpRequest();
        req.setEndpoint(System.Label.EndPoint);
        req.setMethod('POST');
        req.setHeader('X-HAPI-Signature','b7ua89TY1m6hHawC8v+ETX/SK7o=');
        req.setHeader('Content-Type', System.label.Content_Type); 
        req.setBody(jsonString);
        Http http = new Http();
        if(!test.isRunningTest()){
            HTTPResponse res = http.send(req);
            System.debug(res);
            System.debug('resp body+++'+res.getBody());
        } 
    } 
     
    public static Blob generateHmacSHA1Signature(String canonical_str, String secreteKey){ 
             Blob mac = Crypto.generateMac('HMacSHA1', Blob.valueof(canonical_str), Blob.valueof(secreteKey));
        	 String strSignature = EncodingUtil.base64Encode(mac);
             System.debug('strSignature11++'+strSignature);
             return mac;
         }

hi,
I have a favourite button which fetches the items which has been ordered more than twice.
This is my controller

    Public List<Menu__c> favmenu {get;set;}

           if(favmenu.size()>0)
               nofavourites = 'Choose from your favourites';
           else
                nofavourites='No favourites yet';

When i m testing for favmenu.size()>0 ..... it is working fine....but for the else part, when the soql query is not fetching any item, it is showing the error

I have a variable 'd' that captures the current date time.
In the same page i have a button inside jquery which is redirecting to a new page in new window.
I want to pass the variable d  in the url.
Code:
var d = new Date();
The url is :   '<a href="/apex/vfp_KOT?oid=" class="js-newWindow" data-popup="width=500,height=600"><button type="button" class="btn btn-primary">Print KOT</button></a>&nbsp;&nbsp;&nbsp;&nbsp;'+

New Window :  
$(document).ready(function(){
            $('.js-newWindow').click(function (event) {
                event.preventDefault();
                var $this = $(this);
                var url = $this.attr("href");
                var windowName = "popUp";
                var windowSize = $this.data("popup");
                //alert($.session.get('sessionoid'));
                var noid = $.session.get('sessionoid');
                var urlnew = url+noid;
                window.open(urlnew, windowName, windowSize);
            });
        });
I have a jquery popup window which has image , Dish name,quantity and price for various rows. I am able to fetch the data for each row and save in the back end. Now I want to add one text box in each row , showing the remarks .But I am not able to save the remark data from frontend to backend.

Code:
var products = ProductManager.getAllProducts();
      $.each(products, function(){
        var total = this.quantity * this.price;
        $cartTable.append(
          '<tr title="' + this.summary + '" data-id="' + this.id + '" data-price="' + this.price + '">' +
          '<td class="text-center" style="width: 30px;"><img width="30px" height="30px" src="' + this.image + '"/></td>' +

I m getting the error System Exception: List has no rows for assignment to SObject
 
I am using a jquey incrementor and decrementor button in add to cart vf page for increasing and decreasing quantity.Initially i was using a number field 

and the code below is working fine to increment the cart value
 $(document).on("input", "." + classProductQuantity, function () {
      var price = $(this).closest("tr").data("price");
      var id = $(this).closest("tr").data("id");
      var quantity = $(this).val();
      alert(quantity);
      alert(price);
      $(this).parent("td").next("." + classProductTotal).text("Rs " + price * quantity);
      ProductManager.updatePoduct(id, quantity);

      $cartBadge.text(ProductManager.getTotalQuantity());
      showGrandTotal();
      showDiscountPrice();
    });

As number field is not working in tablet, I am using jquery to replace the number field.

var drawTable = function(){
      var $cartTable = $("#" + idCartTable);
      $cartTable.empty();

      var products = ProductManager.getAllProducts();
      $.each(products, function(){
        var total = this.quantity * this.price;
        $cartTable.append(

I am not able to understand what i should write for the PageReference.
I have a custom object Order__c with fields Tables__c(Table No) and Status__c(Picklist-In Progress/Completed). 
Another object Table__c having table no.
In the first page i have a lookup saying enter table number.....once i select a table no. and click next then from Order__c object i want to check if there is a record in custom order object with the table no. which i selected and status is equal to "In Progress".
if yes I want to store the existing order id in a variable 'existingorderid' and pass it in URL.
if no then set the existing order id as null.
Code-:
public with sharing class ctr_firstController {
 
       Public String tout { get; set;}
       Public String tablen{get;set;}
       Public  Tables__c  Table{get;set;}
       Public  Tables__c  Table1{get;set;}
       
       Public List<Order__c> eoid{get;set;}
       Public String exoid {get;set;}
       public String existingorderid {get;set;}
       
    public  ctr_firstController(){        
       Table = new Tables__c();
             
   }
   
   public Tables__c getTables() {
        return Table1;
    }

    public PageReference go() {
        
        String tableno =Table.TablesLU__c; 
       Table1 =  [select id, Name, Reserved__c from Tables__c where id=:tableno limit 1];
       Table1.Reserved__c= True;
       update Table1;
       
       eoid = [select id, name, Tables__c ,Status__c from Order__c where Tables__c=:Table1.Name and Status__c=:'In Progress' limit 1];
       if(eoid.size()>0)
           existingorderid = eoid[0].id;
       else
           existingorderid = null;

        pagereference ref = new pagereference('/apex/vfp_Home?exoid='+existingorderid+'&tablen='+tableno+'&tout=false');
        ref.setredirect(true);
        return ref;
        
        
    }




WHEN I AM USING THIS CODE ,THE NEXT PAGE URL IS SHOWING(exoid=null) instead of showing the id

I have used the online Hmac generator and tested an API. Now I want to do the same thing using apex code.

I am not getting the success method by using the mac code generated using the method "Crypto.generateMac()".

Getting the response as invalid signature.

I am using a jquey incrementor and decrementor button in add to cart vf page for increasing and decreasing quantity.Initially i was using a number field 

and the code below is working fine to increment the cart value
 $(document).on("input", "." + classProductQuantity, function () {
      var price = $(this).closest("tr").data("price");
      var id = $(this).closest("tr").data("id");
      var quantity = $(this).val();
      alert(quantity);
      alert(price);
      $(this).parent("td").next("." + classProductTotal).text("Rs " + price * quantity);
      ProductManager.updatePoduct(id, quantity);

      $cartBadge.text(ProductManager.getTotalQuantity());
      showGrandTotal();
      showDiscountPrice();
    });

As number field is not working in tablet, I am using jquery to replace the number field.

var drawTable = function(){
      var $cartTable = $("#" + idCartTable);
      $cartTable.empty();

      var products = ProductManager.getAllProducts();
      $.each(products, function(){
        var total = this.quantity * this.price;
        $cartTable.append(
          '<tr title="' + this.summary + '" data-id="' + this.id + '" data-price="' + this.price + '">' +
          '<td class="text-center" style="width: 30px;"><img width="30px" height="30px" src="' + this.image + '"/></td>' +
          '<td>' + this.name + '</td>' +

So, the problem is the value is increasing and decreasing properly.But when i am closing the cart ....the value is getting reset to the initial value...ie it is not holding the value.
User-added image
and also the quantity and price is not getting multiplied.
