I have used form.element to prepopulate a form :
form = crud.create(db.data, onaccept=give_update_permission)
# add current date as default form
form.element('input', _name="date")['_value'] =
> time.strftime("%Y-%m-%d")
At this point, form is still not a string but an HTML Helper which provides
DOM access.... (Correct me if I'm wrong).
Are there some cons for this method (I prefer it as it does not alter the
model defaults).
