Could you implement a FormValidator subclass which took a table name
as a parameter to __init__? That way you could use the plain old
@validate. (untested code follows)
class TableValidator(FormValidator):
def __init__(self, name, *l, **kw):
real_validator = formsByTable[name]
self.__dict__.update(real_validator.__dict__) # tricky, don't
know if this will work....
