Thank you

Bhaiya, 28:31 pe joh bhi aapko name aur rating mile the, uspe query karke agar account list ka size >0 hojata toh pata chal jata duplicate hai ya nahi
lekin aap last me dubara 2 for loop kyu use kiye?

[@pantherschools]

inner loop will make sure ki hm add error sahi record pe kr rahe hai jiska duplicate hai na ki kisi bhi record me

[@devarghch]

@@pantherschools Got it Bhaiya! Aapka class sunke bahut maza aata hai aur seekhne ko bhi milta hai :D

[@rohittanwesh7608]

Thank you amit Bhai..but i have a doubt apex best practice says avoid SOQL inside for loop so why you use inside

[@pantherschools]

Hello 👋,
You should have watched the complete video because I have made the query on purpose and then removedb

[@sagarr7940]

Have a quick question on the soql query I’m not sure how we are adding a filter with list of new records. As these records are not yet committed to sf so how can we get the id from those records ? Can you give some insight on this please @pantherschool time stamp 19:28 min

[@pantherschools]

The scenario we are talking about here in this timestamp is for update and in case of before update we will have the records id

[@sagarr7940]

@PantherSchool how can we know that we need to type cast the values when we are passing Trigger.oldMap? also in the dispatcher System.TriggerOperation?

[@pantherschools]

Everytime you want to pass the Map from the Dispatcher class to the Handler class and those maps are part of the Trigger Context variable.

[@Harpreeth29]

Sir location record is created but under location record account field is blank
please tell me where I made mistake and if I use whatId then code is not running.
public static void createLocationUnderAccount(List accountList) {

List locationList = new List();

for(Account acc : accountList) {
// prepare a location record

for (Integer i = 0 ; i < acc.NumberofLocations__c ; i++ ) {
Location__c loc = new Location__c();
loc.Name = 'created from account Trigger ' + acc.Name;
loc.Account__c = acc.Id;
loc.OwnerId = acc.OwnerId;
locationList.add(loc);
}


}

insert locationList;
}

[@pantherschools]

check the event of your apex trigger. it should be after insert

[@Harpreeth29]

@@pantherschools Thanks sir now problem is solved and your playlist is very useful for understanding salesforce development.🙏🙏

[@rucha520]

How to handle first trigger in bulk scenario ?

[@pantherschools]

I didn't get which triggere you are talking about. But we have talked about how to make them bulkified

[@rucha520]

​​@@pantherschools in the first trigger prevent duplicate contact if we insert using collections then duplicates will be skipped.

At 43:34 you said u will explain later. Can u please tell where to find bulk handling

[@pantherschools]

@@rucha520 We have covered in the coming lectures. Please keep watching those.

[@nikhiltripathi2760]

List accList = [SELECT Id,Name,Rating FROM Account WHERE NAME =:acc.Name AND Rating=:acc.Rating AND ID !=:acc.Id];

[@pantherschools]

Good 👍
