Natural Sort Grocery Crud results
===

Grocery Crud provides the function order_by:

    void order_by(mixed $order_by [, string $direction] )

However the field I need to sort is a varchar and I need to perform natural sorting. The MySQL query which correctly sorts the list is as follows:

    ORDER BY 0+'field_name' ASC

Is there any way to specify '0+' in Grocery Crud?


thanks
