You can create your own field-level validators
class validator:
def __init__(self,error_message): self.error_message=error_message
def __call__(self,value):
if success: return (value,None)
else: return (value,self.error_message)
both form.accept and crud.create/crud.update take a parameter
onvalidation
onvalidation can point to a function that takes a form, reads
form.vars and writes form.errors
def f(form):
if not form.vars.a==form.vars.b: form.errors.b="should be == a"
form = crud.create(...., onvalidation = f)
