This was also one of the strangest things I found out with formlib.....
I found that returning {} also works.
The validator is supposed to return a list of errors. Neither '' nor {}
are lists. () is a list. I use
@form.action("Cancel", validator=lambda *a: ())
def cancel(self, action, data):
...
But this is clearly a design weakness if there is no other way of
doing it. Something like validator=NULL_VALIDATOR would be fine, or
some kind of decorator.
+1 for allowing
@form.action("Cancel", validator=form.no_validation)
I added something similar to plone.app.form, but there really, really
should be support for this use case in formlib in a non-hacky way.
We happily accept patches through collector entries. Actually, aren't
you a committer? :)
No, not yet, paperwork scares me. And I'm looking into it. I'm just not
quite sure I (want to) understand the full validation mechanism in
formlib. We could obviously have such a null-validator in formlib itself
for import. However, I wonder if it shouldn't be something a bit less
hacky, e.g. a different type of decorator or some different option
passwed to the @form.action decorator.
