Ronny,
This is fabulous...thank you so very much. If you don't mind me
asking, can you give me an example of how you implemented this method
in your Class? In my case, I've defined the field as a DecimalField
type, but that brings up an error. Did you define some sort of custom
save method around that? Thank you; I really appreciate it.
