Hi all,
Just wondering what the current status of AJAX in Zope 3 is and how best
to get started with it. I believe it would be useful to my work, but I'm
not sure where to start. I know work is going on, but not sure what is
going to be officially part of Zope 3 and what is just proof-of-concept.
I'll probably go with whatever is likely to become part of official Zope 3
or its extensions.
My specific interests for the moment are AJAX-enabled widgets, such as a
dropdown widget whose vocabulary changes based on the selection in a
different dropdown within the same form. I don't want to pre-cache all
possible vocabs, since there could be a quite a few large vocabs in my
application. Perhaps there is a better way to do it, but I don't want to
reload the entire page to update the widget. It is an
accounting/inventory application that requires fast data entry.
Any tips on how to get a Zope 3 sandbox into s state where I can do this
sort of thing, and any specific tips for AJAXifying widgets?
Cheers,
Sam.

Hello!
I use http://script.aculo.us/ AJAX-library. I attach my
'AutoCompleteWidget' for Zope3.
#-*- coding:utf-8 -*-
$Id$
from zope.interface import implements
from zope.app import zapi
from zope.app.form.browser import TextWidget, FloatWidget
from zope.app.form.interfaces import ConversionError
from zope.proxy import removeAllProxies
from z3fin.schema import convert_decimal
template = %s
div class=autocomplete id=%s_autocomplete/div
script type=text/javascriptnew Ajax.Autocompleter('%s', '%s_autocomplete', '%s/auto_complete', {})/script
class AutoCompleteWidget(TextWidget):
cssClass = 'actextType'
def __call__(self):
url = zapi.absoluteURL(self.context.context, self.request)
html = super(AutoCompleteWidget,self).__call__()
res = template % (html, self.name, self.name, self.name, url)
return res
# Decimal widget
class DecimalWidget(FloatWidget):
def _toFieldValue(self, input):
if input == self._missing:
return self.context.missing_value
else:
try:
return convert_decimal(input)
except:
raise ConversionError(_(Invalid floating point data), input)
def _toFormValue(self, value):
Converts a field value to a string used as an HTML form value.
This method is used in the default rendering of widgets that can
represent their values in a single HTML form value. Widgets whose
fields have more complex data structures should disregard this
method and override the default rendering method (__call__).
if value == self.context.missing_value:
return self._missing
else:
res = removeAllProxies(value).to_eng_string()
return res.replace('.', ',')
