Solve the following python programming problem given the following code:
@ skipUnlessDBFeature ('supports_transactions') 
def test_reuse_cursor_reference(self) : 
    '
        Make sure transaction closure is enforced even when the queries are performed
        through a single cursor reference retrieved in the beginning
        (this is to show why it is wrong to set the transaction dirty only when a cursor
        is fetched from the connection).
        ' 
    @ commit_on_success 
    def reuse_cursor_ref() : 
        '
            Fetch a cursor, perform an query, rollback to close the transaction,
            then write a record (in a new transaction) using the same cursor object
            (reference). All this under commit_on_success, so the second insert should
            be committed.
            ' 
        cursor = connection.cursor () 
        cursor.execute ('INSERT into transactions_regress_mod (fld) values (2)') 
        transaction.rollback () 
        cursor.execute ('INSERT into transactions_regress_mod (fld) values (2)') 
reuse_cursor_ref () 
    transaction.rollback () 
    self.assertEqual (Mod.objects.count (), 1) 
    obj = Mod.objects.all () [0] 
    self.assertEqual (reuse_cursor_ref.fld, 2) 

    
    

    Fix the buggy line: self.assertEqual (reuse_cursor_ref.fld, 2)

#Here is Python program to fix the buggy line: self.

self.assertEqual (obj.fld, 2)
