Just tried it, but it doesn't seem to be very useful since you cannot specify and validator arguments, and I had to fix some things first (see http://bitbucket.org/cito/formencode/changeset/e39881f76131). I've added the examples to our Wiki now: http://wiki.w4py.org/webwareandformencode.html -- Christoph -- ___ Webware-discuss mailing list Webware-discuss@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/webware-discuss
Re: [Webware-discuss] Example howto use FormEncode with Webware-1.1b1
Thank your for your excellent help.
The basic example works.
Next step is your SchemaBuilder suggestion.

Thanks, I was not aware of that example. Seems it was actually written
for Paste WebKit (http://pythonpaste.org/webkit/).
As you noticed it uses htmlform which is deprecated; you must use
htmlfill directly. You must also add a name="color" attribute to the
checkboxes to make these work.
It seems your problem is that the formencode errors are now unicode, so
you must encode these. Here is how I got it working with the current
Webware (I simplified it a bit by not using Webware actions):
class form(Page):
schema = FormSchema()
def awake(self, trans):
Page.awake(self, trans)
try:
fields = self.request().fields()
if 'name' in fields:
fields = self.schema.to_python(fields, self)
else:
fields = self.getDefaults()
except formencode.Invalid, e:
errors = dict((k, v.encode('utf-8'))
for k, v in e.unpack_errors().iteritems())
else:
errors = None
self.rendered_form = formencode.htmlfill.render(form_template,
defaults=fields, errors=errors)
def writeContent(self):
self.write(page_style % self.rendered_form)
def getDefaults(self):
return dict(age='enter your age', color=['blue'])
Let me know how it works for you.
Btw, instead of using a schema, you could also embed the validation info
in the form template and use the SchemaBuilder to parse these.
