Sphinx is already on our future list: http://wiki.w4py.org/futurework.html You can use the Wiki to add recipes and tutorials as drafts; they don't need to be polished. The Wiki and the existing docs can then be used as a starting basis for creating the Sphinx docs (which should be tested and proof-read). Anything that has become obsolete or has been taken over to the Sphinx docs can then be removed from the Wiki. -- Christoph -- ___ Webware-discuss mailing list Webware-discuss@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/webware-discuss -- ___ Webware-discuss mailing list Webware-discuss@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/webware-discuss

Btw, I just fixed the original Webware example in FormEncode which was broken because of the missing HTMLForms and had some more small problems (e.g. the Unicode issue you reported).

Re: [Webware-discuss] Example howto use FormEncode with Webware-1.1b1 (2)
Thank you for your reply
My test setup is:
. fedora 11
. python 2.6
. formencode in site-packages/formencode
(had to add the i18n directory) from [2]
. webware-1.1.b1
. using utf-8
I got the example from a direct download from formencode.org:
. [2] svn co http://svn.colorstudy.com/FormEncode/trunk FormEncode
(examples directory: WebwareExamples/index.py)
. you may switch language for formencode in awake
. some lines in save are experimental.
I made some changes following your suggestions.
The german version doesn't break HTTPResponse anymore,
but I still don't understand the mechanics of error catching and so on.
My aim is to have a basic example I can use for my next steps.

Generally, you must output ordinary (encoded) strings in Webware, not
unicode. It's best to always use the same encoding (e.g. latin-1 or
utf-8) and work with encoded strings everywhere inside Webware.

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.
