You don't explain whether you are using oldforms or newforms here. For newforms, override the Field class(es) that you wish to customise and write new clean() methods. Your methods could just call the super-classes clean, catch ValidationError and replace it, or do something more if you wanted. For oldforms, you would need to replace the validator_list entries in the Fields you are interested in, I guess. Have a look at the source code (django/db/models/fields/__init__.py) to see how validator_list is used in each class you are interested in. In either case, if you are creating a form directlly from the model, instead of manually, you pretty much have to live with the error messages we give you. The automatic creation is always designed for teh simple, straightforward case. Any customisation requires a bit of code on your part.
