Trigger to update parent checkbox if child record has atleast 1 checkbox ticked.

I have the following requirement :

object : Product
fields: 
1. New (checkbox)
2. Old ( checkbox)
3. Sold(checkbox)
4. Out of stock(checkbox)
5.Item (lookup to Itemsale)

object: Itemsale

1. New (checkbox)
2. Old ( checkbox)
3. Sold(checkbox)
4. Out of stock(checkbox)

how to write the trigger so that atleast one record of itemsale has "New" checked then it will update parent field "New" as checked?

Hi Shraddha,

This might help you 
/* Please update object names and fields accordingly */

trigger sampleTrigger on Itemsale(after insert){
	set<Id> productIdsToUpdt = new set<Id>();
	for(Itemsale oItem:Trigger.New){
		if(oItem.new){
			productIdsToUpdt.add(oItem.productId__c);  //assuming productId__c is field name for relationship
		}
	}
	
	if(productIdsToUpdt.size()>0){
		list<Product__c> productsToUpdt = new list<Product__c>([SELECT id FROM Product__c WHERE ID IN :productIdsToUpdt]);
		update productsToUpdt
	}	
}

 

Thanks,
N.J

You might have to update all expected fields in if condition you you want to update multiple fields on parent.
