As a beginner MAC OS user with Salesfoce

I am a window user & shifted on MAC recently, this move was not easy & come up with several issues. Struggling phase with MAC is still going on because when you start using MAC you realize that you don't know even simplest thing too :) a bit frustrating!


Couple of issued while setting up Eclipse + Force.com IDE for MAC OS, just sharing experience so you can save your time if you face this kind of issues.

1-In my eclipse I did not see autocomplete after foce.com ide installation, tried various tricks from internet but nothing works, after a lot of wasting time I came to know that I should install version 30 to see autocomplete feature, probably this is not available in latest releases.

Here is how you can do it- I am assuming you are already have an idea of below link
Foce.com IDE

When you add a "Foce.com IDE" & click on add there is a checkbox "Show Only latest Version Of Available Software", you need to uncheck it.
You will see couple of versions for Force.com IDE. You should select version 30 & after that install it.You will see autocomplete after this installation.


2-The other issue, which I was facing, is
 "An internal error occurred during: "Computing size". The profile is currently in use." 

After wasting a lot of time I came to know that, error is due to I am trying to install eclipse + Force.com Ide on FAT 32 partition. & Due to that it is not installing "Force.com IDE".
I moved it on MAC drive (Mac OS Extended (Journaled)) & that starts working.

3.I was trying to install the data loader on MAC but many people said dataloader is not build for MAC, it is build for windows only, after wasting some time, I got the version for MAC.

You can go to your salesforce org Setup >> Data Management >> Data Loader >> Download for MAC

4.I also tried if data loader command line tool can work on MAC, but still struggling with this. Probably it is not for MAC, OR it will take some time if any trick can work. But for now it is not working.

Also noticed that if you are using command line in windows & using latest version that will not work, you need to download version 30 for this & that will work.
You can download older version from this link.

5. As a beginner in MAC I noticed that I see Question mark for some app's. This one is not related to salesforce ☺.
When I click on them it will show a popup with that app & application folder. I don't understand it why it is doing like this even I have installed app.
At other hand when I am trying to removing some dmg file from hard drive it is showing a message that it can not be deleted.

Solution is very simple for this issue:-
a-when it shows a popup, you need to move that app in application folder, this is what it is trying to tell user by showing that popup but as a beginner it is not easy to understand.

b- When I did this, I could delete those dmg files too. To check from where app is working go to dock right click on app & click show in finder, it will show the place from where app is running.

c-All apps should run from application folder, so first move app in application folder & then drag & drop that app in dock. Right click on this icon & select "Keep this in doc" & that's it.

A Web Service CallOut Per Minute In Between Business Hours

There was a very specific requirement from customer, as per the requirement he wanted to call a external websrvice in every minute during the business hours. I tried several ways to do it but that was really not simple. Even I was not sure it can hit any governor limit. I did google a lot for this but there was no help in case of per minute. Finally started to get if there is any solution in salesforce for this, without having confidence is this really possible in salesforce. But finally I got the solution & the best thing is it works without hitting any kind of governor limits. Here is the solution which can help if you stuck this kind of requirement.

#1-Create a new object called “Scheduled_Job__c”. This object will have below fields –
Request_DateTime__c – Type DateTime
Response__c – Type Long Text Area(32768)

This object will be used in two ways latter-
#A-track the request time &
#B-What is the response from the external web service.
#2-I created a batch class which allows callouts.

global class ScheduleLeads implements Schedulable,Database.AllowsCallouts {
 global void execute(SchedulableContext ctx) { 
      init(); 
 }
}

#3-Created a method in this class called ScheduleJob which will basically can be called from execute anonymous to schedule this job.

public static void ScheduleJob(){
 boolean isNeedToSchedule = true;
 String strSchedule = '';
/*here notice that we are adding a minute in current time, means it will be scheduled for next minute, you can change it even if you want to call every n minutes*/
 DateTime dt = Datetime.now().addMinutes(1);
/*Let’s say business hours is from 10 AM to 8 PM*/
 if(dt.hour() >=19 && dt.minute() >= 59){ 
         isNeedToSchedule = false;
 }else{
     strSchedule = '0 ' + dt.minute() + ' ' + dt.hour() + ' ' + dt.day() + ' ' + dt.month() + ' ?' + ' ' + dt.year(); 
     isNeedToSchedule = true;
 }
 if(isNeedToSchedule){
   String cronid = System.schedule('CalloutService_' + Datetime.now().getTime(), strSchedule, new ScheduleVWLeads());
  
   List listOfScheduledJob = [Select Id,Response__c from Scheduled_Job__c Order by CreatedDate DESC LIMIT 1];
   if(listOfScheduledJob != NULL && !listOfScheduledJob.isEmpty()){
    /*try{ 
     delete listOfScheduledJob;
    }catch(Exception ex){
     system.debug('exqqq::--->>>>' + ex);
    }*/
   }
   Scheduled_Job__c objScheduledJob = new Scheduled_Job__c();
   objScheduledJob.Name = cronid;
   objScheduledJob.Request_DateTime__c = datetime.now();
   insert objScheduledJob;
 }      
}

#4-Create another method called init

@future(callout=true)
  public static void init(){
     HttpRequest req = new HttpRequest();
  Http http = new Http(); 
  req.setMethod('GET');
  String requrl = 'YOUR_WEBSERVICE_URL'+ '?type=' + XYZ;
  req.setEndPoint(requrl);
  HTTPResponse res;
  if(!Test.isRunningTest()){
   Blob headerValue = Blob.valueOf('YOUR_WEBSERVICE_USERID' +':' +'YOUR_WEBSERVICE_PASSWORD');
   String authorizationHeader = 'Basic ' + EncodingUtil.base64Encode(headerValue);
   req.setHeader('Authorization', authorizationHeader);
   req.setTimeout(120000);
   res = http.send(req);
  }else{
   res = new HttpResponse();
   res.setHeader('Content-Type', 'application/json');
   res.setBody('DUMMY_RESPONSE_IN_CASE_OF_TEST_EXECUTES');
   res.setStatusCode(200);
   res.setStatus('Ok');
  } 
  String resBody;
  if(res != NULL){
   resBody = res.getBody();
   JSONParser parser = JSON.createParser(resBody);
   while (parser.nextToken() != null) {
    /*PROCESS YOUR RESPONSE HEREE */
   }
   ScheduleJob();
  }
  
 }

Here one important point is we are calling the schedulejob method in init again so this is scheduled for next minute.
Now if you start this job at some particular time daily let’s say when business start 10 AM in morning, go to schedule job & schedule a job by using this class. That’s it. The job will start on regular time daily & in code we are having a condition when it will stop. So in this way the job will execute from 10 AM to 8 PM daily.
You can either keep ScheduleJob records for tracking or can delete if not needed. In the above code there is a piece of code which is commented & that is deleting the ScheduleJob object records.

Happy ending! :)

Avoid simultaneous update/ Control same record if already opened by someone in edit mode & show a message to end user

Recently I came across a requirement where client wanted to track if any other user also open the same record to edit, in this case he wanted to show a message to second user so he can edit the same record latter.

To solve this I created a custom setting let’s say Control_Record_Edit__c. Created few other fields to track edit mode –

Name
Edit_DateTime__c
User_Id__c

Name:- field will save record id which is opened in edit mode by someone.
Edit_DateTime__c:- field will tell us how long someone open a record in edit mode
User_Id__c:- field will tell us who open that record in edit mode.


Now let’s say we want to track lead record. We will create a new VF page that will be called LeadEdit.page. In this page we will have a function called init which will basically insert a record in our custom setting, so next time whenever someone open the same lead it edit mode we can check in code & show a message that another user is already opened this lead in edit mode.

<apex:page standardController="lead" extensions="LeadEditController" action="{!init}">
 <apex:form id="form1">
  <apex:outputPanel rendered="{!isNeedToShowMsg}">
   <apex:pageMessages id="error"/>
   <apex:commandButton value="Go To Lead" action="/{!objLead.Id}" style="margin-left: 20px;"/>
  </apex:outputPanel>
 </apex:form>  
</apex:page>

Class code is as below

public with sharing class LeadEditController {
 public Lead objLead {get;set;} 
 public boolean isNeedToShowMsg {get;set;}
 public LeadEditController(ApexPages.StandardController stdController){
  objLead = (Lead)stdController.getRecord();
 }
  
 public PageReference init(){
  isNeedToShowMsg = false;
  PageReference pr = NULL;
  List listOfControlLeadUpdate = [SELECT Id,User_Id__c,Edit_DateTime__c from Control_Lead_Update__c where Name=:objLead.Id and User_Id__c !=:Userinfo.getUserId() LIMIT 1];
  if(listOfControlLeadUpdate != NULL && !listOfControlLeadUpdate.isEmpty()){
   List listOfUser = [Select Id, Name from User where Id=:listOfControlLeadUpdate.get(0).User_Id__c LIMIT 1];
   if(listOfUser != NULL && !listOfUser.isEmpty()){
    String Msg = 'Another User ' + listOfUser.get(0).Name + ' already start editing the same lead at '+  listOfControlLeadUpdate.get(0).Edit_DateTime__c.format()  +', Please wait for sometime & click on edit button again!'; 
    ApexPages.Message apexmsg = new ApexPages.Message(ApexPages.Severity.INFO, Msg);
             ApexPages.addMessage(apexmsg);
             isNeedToShowMsg = true;
   } 
   
  }else{
   Control_Lead_Update__c objControlLead = new Control_Lead_Update__c();
   objControlLead.Name = objLead.Id;
   objControlLead.Edit_DateTime__c = datetime.now();
   objControlLead.User_Id__c = Userinfo.getUserId();
   try{
    insert objControlLead;
   }catch(Exception ex){
    system.debug('exception::-->>>' + ex);
   }
   pr = new PageReference('/' + objLead.Id + '/e?nooverride=1&retURL=/apex/LeadCancel?Id=' + objLead.Id);
  } 
  return pr; 
 }
 
 public PageReference initCancel(){
  LeadHandler.ReleaseEditModeForOthers(new List{objLead});
  PageReference pr = new PageReference('/' + objLead.Id);
  return pr;
 }
}

Here after this one other issue appear when user click on cancel, if user open a lead & click on cancel we should remove his record from custom setting but the problem is cancel override is not available in salesforce. To handle this we created another page that is called LeadCancel & we are passing it in the retURL parameter.

<apex:page standardController="lead" extensions="LeadEditController" action="{!initCancel}">

</apex:page>

now in the class code there is a method initCancel, that is basically deleting the record from custom setting if a user open a lead & click on cancel button. also we are passing this cancel page in retuURL parameter so when user click on cancel it will be back to our page.

There is only one point here which is important, if a user open a lead & close it by browser close button then we can not track that action & in that case no one can edit the same lead until that record does not removed from custom setting.
