Solve the following python programming problem given the following code:
@ method_decorator (catch_and_raise_exceptions) 
def get_total_row(self) : 
    def _clean_total_row(val, col) : 
        if isinstance (val, numbers.Number) : 
            return val 
else : 
            if col.calculate_total : 
                return 0 
return '' 
def _get_relevant_column_ids(col, column_id_to_expanded_column_ids) : 
        return column_id_to_expanded_column_ids.get (col.column_id, [col.column_id]) 
expanded_columns = get_expanded_columns (self.column_configs, self.config) 
    qc = self.query_context () 
    for c in self.columns : 
        qc.append_column (c.view) 
session = connection_manager.get_scoped_session (self.engine_id) 
    totals = qc.totals (session.connection (), [column_id for col in self.column_configs for column_id in _get_relevant_column_ids (col, expanded_columns) if col.calculate_total], self.filter_values) 
    total_row = [_clean_total_row (totals.get (column_id), col) for col in self.column_configs for column_id in _get_relevant_column_ids (col, _clean_total_row)] 
    if (total_row and (total_row [0] is '')) : 
        total_row [0] = ugettext ('Total') 
return total_row 

    
    

    Fix the buggy line: total_row = [_clean_total_row (totals.get (column_id), col) for col in self.column_configs for column_id in _get_relevant_column_ids (col, _clean_total_row)]
