This is a simple TextInput widget that uses my Currency object.
I placed my Currency object in the Django utils directory because I integrated a set of currency objects into the Admin app ( here ) and it was just easier to have everything within Django.
The rest of the series: Currency Object, Currency Form Field, Currency DB Field, Admin Integration
