Yes of course, but I thought some "stock" date validators are worth to discuss. There are IS_INT_IN_RANGE and friends, then why not IS_DATE_IN_RANGE (maybe with defaults to None for both min and max date). > 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) But this way the validation is not built into the form/model :( > > On Jan 11, 6:13 am, "KONTRA, Gergely" <[email protected]> wrote: > > > Hi! > > I have a status "enumeration" for a status in one of my tables.
