Trailhead class error

This is the Challenge:

To pass this challenge, create an Apex class that inserts a new account named after an incoming parameter. If the account is successfully inserted, the method should return the account record. If a DML exception occurs, the method should return null.The Apex class must be called 'AccountHandler' and be in the public scope.
The Apex class must have a public static method called 'insertNewAccount'.
The 'insertNewAccount' method must accept an incoming string as a parameter, name the account after the parameter, insert it into the system and then return the account record.
The 'insertNewAccount' method must also accept an empty string, catch the failed DML and return null.


My Class:

public class AccountHandler {

    public static Account insertNewAccount (String accName, Account a) {
         try{   
          a.name = accName;
    
         insert a;
        return a;
        }
        catch(Exception e) {
            return null;
        }
    }    
}

I think this line has you confused:

The 'insertNewAccount' method must accept an incoming string as a parameter, name the account after the parameter, insert it into the system and then return the account record.

It isn't saying that there should be an account parameter following the string parameter, its saying that the method should take a single string parameter and use that as the name of the account. Thus the account should be a method variable rather than a parameter.

Hi Andrea lanni, 

Your code has worked well thank you, could you please reveal on thing for me. 

what is mean of this line: "name the account after the parameter" 
Andrea IanniAndrea Ianni
It sounded a little "weird" to me too. I interpreted it as: "use the String passed as parameter for giving the name to the Account".

while i am executing  this program i am facing this error like 

Challenge not yet complete... here's what's wrong: 
There was an unexpected error in your org which is preventing this assessment check from completing: System.DmlException: Delete failed. First exception on row 0 with id 0019000001Q83SEAAZ; first error: FIELD_CUSTOM_VALIDATION_EXCEPTION, Account has relatedList so deletion is not possible: []

I wrote a trigger for delete. from where this error is rising but why is it checking over it.
Thanks in advance.
monika sdfcmonika sdfc
after deleting this delete trigger then it works..but why can any explain it.
Andrea IanniAndrea Ianni
The problem is that your account had "children", as Contacts, Opportunities, and so on. When you tried to delete it Salesforce returned the error because otherwise the look-ups on the "children" pointing to that account you wanted to delete would have pointed to something not existing.

I guess that you deleted the "children" with your trigger. Then you were able to delete the Account too.

The only question is: why the deletion of the Account? Maybe you have something that triggers the deletion somewhere conncted to that code. I'm sorry I cannot help you more than this.

Do not use 'account' in  Account account = new Account(Name = name);
User 'acc' or something else.
Check if it helps.

@Andrea Ianni - could you break down your code a bit, just to help my understanding? I had a very similar peice of code as yours, but mine didn't work because instead of:
public static Account insertNewAccount (String accName)

I had

public static Account insertNewAccount (String asd) 

Now, does accName have to be something specific? I don't quite understand...
Andrew Smith 40Andrew Smith 40
Also, I found this is bare essential, minimum amount of code to make this work (I tend to like the SIMPLIEST version of anything, then add on what's needed from there):
 
public class AccountHandler {

    public static Account insertNewAccount (String accName){
          
            try{
                Account asd = new Account(Name=accName);
                insert asd;
            } catch(Exception e){
                return null;
            }
        
    }
    
}

If you have this error :
There was an unexpected error in your org which is preventing this assessment check from completing: System.DmlException: Delete failed. First exception on row 0 with id 0019000001Q83SEAAZ; first error: FIELD_CUSTOM_VALIDATION_EXCEPTION, Account has relatedList so deletion is not possible: []

You should look in your Account triggers and delete the one causing the probleme.

Hi all,

try using the code.

public class AccountHandler {
    public static Account insertNewAccount(String accName){
       Account asd = new Account();
               asd.name = accName;
        try{
            insert asd;
                      
        system.debug('insreted'+asd.name);
        return asd;
        }
        catch(Exception e){
        system.debug('Exception');   
        return null;
    }
    }
    }

 

And below on anonymous window
AccountHandler.insertNewAccount('testsample');

 

 

Rgards,

Anamika
