Because valid html requires a non-empty action, I'd like to make the
effort to specify self-submission as easy as possible. I've been
thinking along these lines:
FORM(..., _action=request._self)
where:
class Request(Storage):
...
def _self(self):
return URL(r=self, args=self.args)
or two methods, if there's a reason you don't want the args. Depending
on which is more commons, _self() and _self_args() or _self() and
_self_only, say.
Or even simpler:
FORM(..., r=request)
where FORM would fill in action with a self-reference if it's not
otherwise specified (instead of setting it to '' as it does now). (And
depending on whether we need with-args and without-args flavors.)
Again, the general idea is that a) valid html is highly desirable, b)
self-submission is a very common case, and consequently c) it's
worthwhile making that case as concise as possible.
