Abhinav Admin Requesting for the After Triggers Code for the Following Requirement
Hi all, I Have Two Objects called Student and Payment Student is the Master Object and Payment is the Child Object In those i have a common field called Fee When i enter a Fee field in the parent object its child objects also fill with the same value so can any one tell me the code for this to achieve After Triggers
I think the easiest is a cross object formula to get the common field displayed on the child record. Something such as:
Student_and_Payment_Student__r.Fee__c
If you want to use a trigger try this:
//I think you would be fine to just use a before trigger
trigger AddFeeToChildren on Student_and_Payment_Student__c (before update, before insert) {
//create map with Id (later referenced as parent Id) and Fee
Map<Id, String> studentAndPaymentMap = new Map<Id, String>();
//creat set to store Id's for query
Set<Id> studentAndPaymentId = new Set<Id>();
for(Student_and_Payment_Student__c spsId : trigger.new){
studentAndPaymentId.add(spsId.Id);
}
//fiil map
for(Student_and_Payment_Student__c sps : trigger.new){
studentAndPaymentMap.put(sps.Id, sps.Fee__c);
}
//get all child payments
List<Payment__c> payment = [Select Id, ParentId, Fee__c from Payment__c where ParentId =: studentAndPaymentId];
for(Payment__c p : payment){
p.Fee__c = studentAndPaymentMap.get(p.ParentId);
}
update payment;
}
Cheers,

Trigger updateFee on Students__c (After insert,After update)
{
set<ID> Ids = new set<ID>();
if(Trigger.isInsert || Trigger.isUpdate)
{
for(Students__c s : Trigger.New)
{
Ids.add(s.ID);
}
}
System.debug(Ids);
List<Students__c> lststdnt = [Select Id,Name,Fee__c from Students__c where Id IN : Ids];
List<Payment__c> lstpymnt = [Select Id,Name,Total_Fee__c from Payment__c where Student_Name__c IN : Ids];
System.debug(lststdnt);
System.debug(lstpymnt);
List<Payment__c> updatepymnt = new List<Payment__c>();
for(Payment__c p : lstpymnt)
{
//p.Total_Fee__c = Student_Name__r.Fee__c ;
updatepymnt.add(p);
}
update updatepymnt;
}
