SFDC_Learner Updating same object field in trigger.new (before update) call
trigger AccDescriptionUpdate on Account (before update) {
set<Id> setIds = new set<Id>();
for(Account objA : trigger.new){
setIds.add(objA.id);
}
system.debug('----set Ids are --->'+setIds);
List<Account> lstA = [select id,name,(select id,name from Contacts) from Account where id in : setIds];
system.debug('---lstA is --->'+lstA);
String sDesc ='';
for(Account objA : lstA){
Integer i= objA.contacts.size();
integer j=1;
for(Contact objC : objA.contacts){
if(j <= i-1){
sDesc = sDesc + objC.name + ',';
j++;
}
else{
sDesc = sDesc + objC.name;
j++;
}
}
system.debug('---sDesc is --->'+sDesc);
objA.description = sDesc; // In before insert why its not updating to my account.
system.debug('---objA.description is --->'+objA.description);
}
}
how can i update the description file in before update event.
I have modified the code, try this :
trigger AccDescriptionUpdate on Account (before update) {
set<Id> setIds = new set<Id>();
for(Account objA : trigger.new){
setIds.add(objA.id);
}
system.debug('----set Ids are --->'+setIds);
List<Account> lstA = [select id,name,(select id,name from Contacts) from Account where id in : setIds];
system.debug('---lstA is --->'+lstA);
String sDesc ='';
for(Account objA : lstA){
Integer i= objA.contacts.size();
integer j=1;
for(Contact objC : objA.contacts){
if(j <= i-1){
sDesc = sDesc + objC.name + ',';
j++;
}
else{
sDesc = sDesc + objC.name;
j++;
}
}
system.debug('---sDesc is --->'+sDesc);
Account acc = trigger.newMap.get(objA.Id); //you have to change the value which is the in the trigger i.e Account present in the trigger.new or trigger.newMap
acc.description = sDesc; // In before insert why its not updating to my account.
system.debug('---acc.description is --->'+acc.description);
}
}
Hope it helps.
It causes,
System.FinalException: Record is read-only
.
Might be your trigger is calling for after update also I think.
Can you just copy the above code in new account trigger and test it once.
It works for me.
