This is a very important question that i would like to complement.
You can use a single custom validator for any kind of parse you want to
perform on any particular field, like this.
class process_field():
def __init__(self, func):
self.func = func
def __call__(self, value):
return (self.func(value), None)
db.define_table("people",
Field("name", "string", length=50,
requires=process_field(str.capitalize))
)
This passes a function to the validator (proccess_field) and outputs the
result of the inserted value. This way you dont need to create many
validators for each field.
I dont know what None is supposed to be, does anyone knows about it?
Thanks.
