Apex trigger: Auto populating a field

Hi,

 

I have created a trigger tfor custom object to auto populate the owner name (lookup) in another field under same object,

 

Here is the code:

 

trigger setOwnerName on Partnership__c (before insert) {
Map<Id,String> userMap = new Map<Id, String>();     
for (User u : [Select Id, Name From User]) 
{        
userMap.put(u.Id, u.Name);  
}   
for (Partnership__c a : Trigger.New)
 {     
 if(a.Account__c == 'AAA Drawloop Testing')
 {
 a.Owner_Name__c = userMap.get(a.OwnerId);   
}
}

 

 

I created a test trigger but I am getting error : System.StringException: Invalid id: AAA Drawloop Testing

 

private class setOwnerNameTest{
    public static TestMethod void OwnerNameinsert(){
           Partnership__c acc = new Partnership__c();
           acc.Account__c = 'AAA Drawloop Testing';
           insert acc;
           test.startTest();
           Partnership__c accNew = new Partnership__c(); 
           accNew.Account__c = 'AAA Drawloop Testing';
           insert accNew; 
           system.assert(accNew.id == null); 
        test.stopTest();
    }
}

 

What I am doing wrong. Please help?

First, here is a small rewrite of the trigger to optimize it:

 

trigger setOwnerName on Partnership__c (before insert) {

Map<Id,User> userMap = new Map<Id, User>([Select Id, Name From User Where ID IN (Select OwnerID From Partnership__c Where ID IN :trigger.new)]);     

   
for (Partnership__c a : Trigger.New)
 {     
 if(a.Account__c == 'ACCTID')
 {
    if(userMap.containsKey(a.ownerID) 
        a.Owner_Name__c = userMap.get(a.OwnerId).Name;   
  }
}
}

 

Secondly,

 

In the test class you need to create the account, then put that ID in Account__c

 

private class setOwnerNameTest{
    public static TestMethod void OwnerNameinsert(){
           Partnership__c acc = new Partnership__c();
           Account acct = New Account(
              Name = 'Test Account',
              ANYADDITIONALREQUIRED FIELDS
            );
            Insert acct; 
          acc.Account__c = acct.ID;
           insert acc;
           test.startTest();
           Partnership__c accNew = new Partnership__c(); 
           accNew.Account__c = acctID;
           insert accNew; 
           system.assert(accNew.id == null); 
        test.stopTest();
    }
}
