Soozee Trigger to update a different custom object
trigger Trigger_Name on CustomObject__c (after insert) {
List<CustomObject__c> emailList = [select id from CustomObject__c where ID in :trigger.newMap.keyset()];
List<OtherCustomObject__c> recordsToUpdate = new List<OtherCustomObject__c>{};
for(CustomObject__c e: emailList){
for(OtherCustomObject__c le : e.letter__r.id ){

}Hello - I would like to update a field in one object based on the creation of a record in aother object.
I get this error when I try to save:
Save error: Loop must iterate over a collection type: Id
Help?
Try this
Assuming that the CustomObject__c has a lookup relation to OtherCustomObject__c
trigger Trigger_Name on CustomObject__c (after insert) {
Set<id> lids = new Set<id>();
List<CustomObject__c> emailList = [select id , letter__c from CustomObject__c where ID in :trigger.newMap.keyset()];
List<OtherCustomObject__c> recordsToUpdate = new List<OtherCustomObject__c>();
for(CustomObject__c e: emailList){
lids.add(e.letter__c);
}
List<OtherCustomObject__c> obj = new List<OtherCustomObject__c>([Select id,emailed__c,date_emailed__c from OtherCustomObject__c where id IN :lids]);
for(OtherCustomObject__c le : obj ){
le.emailed__c=true;
le.date_emailed__c = datetime.now();
recordsToUpdate.add(le);
}
update recordsToUpdate;
}
}

Is there any relation between the two objects??
Try this
Assuming that the CustomObject__c has a lookup relation to OtherCustomObject__c
trigger Trigger_Name on CustomObject__c (after insert) {
Set<id> lids = new Set<id>();
List<CustomObject__c> emailList = [select id , letter__c from CustomObject__c where ID in :trigger.newMap.keyset()];
List<OtherCustomObject__c> recordsToUpdate = new List<OtherCustomObject__c>();
for(CustomObject__c e: emailList){
lids.add(e.letter__c);
}
List<OtherCustomObject__c> obj = new List<OtherCustomObject__c>([Select id,emailed__c,date_emailed__c from OtherCustomObject__c where id IN :lids]);
for(OtherCustomObject__c le : obj ){
le.emailed__c=true;
le.date_emailed__c = datetime.now();
recordsToUpdate.add(le);
}
update recordsToUpdate;
}
}
Thank you so much! This worked great!
