Masie Update a child object based on update on parent object
Hi
May someone please help, I have an object called the rebate that has a lookup relationship to the account object. I want when a field is updated on the account object a field should also be updated on the rebate object but I am having a problem with this trigger.
trigger updateStartDate on Rebates__c (after insert, after update,before update){
Set<Id> accountIds = new Set<Id>();
for(Rebates__c reb :trigger.new){
accountIds.add(reb.Company__c);
}
Map <ID,Account> updateAccounts = new Map<ID,Account>([Select id, Date_Installed__c from Account where id IN: AccountIds]);{
for(Rebates__c reb :trigger.new){
accountIds.add(reb.Company__c);
if(reb.From_Install_Date__c == true && updateAccounts.get(reb.Company__c).Date_Installed__c != null){
if(reb.Product__c == '1t200000024Dtm')
{
reb.Start_Date__c = reb.First_Day_of_the_Month__c;
accountIds.update(reb);
}
else
{
reb.Start_Date__c = reb.Install_Date__c;
accountIds.update(reb);
}
try
{
update accountIds;
}
catch (system.DmlException e)
{
system.debug (e);
}
}
}
}
}

If this is a scenario, then why not write a trigger on account. And when updated, you can identify that this account is associated with which rebate using SOQL and then you can update the rebate too.
I will try that- thanks.
{
set<id> set1=new set<id>();
list<contact> conlistnew=new list<contact>();
for(account acc:trigger.new)
{
set1.add(acc.id);
}
list<contact> conlist=[select id,name,accountid from contact where accountid in:set1];
for(account tempacc:trigger.new)
{
for(contact tempcon:conlist)
{
if(tempacc.id==tempcon.accountid)
{
tempcon.update_from_account__c=tempacc.contact_update_fiels__c;
conlistnew.add(tempcon);
}
}
}
update conlistnew;
}
Your trigger helped me model mine. You are a life saver
Map<id, Account> accountMap = new Map<Id,account>
([select id,name,Phone,(select id,Phone from contacts) from account where id in :trigger.newmap.keyset()]);
list<contact> conupdatelist = new list<contact>();
for (account acc: trigger.new){
list<contact> conlist = accountMap.get(acc.id).contacts;
for(contact con : conlist )
{
con.phone = acc.phone;
conupdatelist.add(con );
}
}
update conupdatelist;
}
