[Zope3-dev] getting started with AJAX
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. ___ Zope3-dev mailing list Zope3-dev@zope.org Unsub: http://mail.zope.org/mailman/options/zope3-dev/archive%40mail-archive.com

Hello!
I use http://script.aculo.us/ AJAX-library. I attach my
'AutoCompleteWidget' for Zope3.

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('.', ',')

there are packages for zope3 which include javascript libraries you may need http://svn.zope.org/z3c.javascript regards, bernd On 19.05.2006, at 11:45, Sam Stainsby wrote: Hi all, Just wondering what the current status of AJAX in Zope 3 is and how best to get started with it.

Re: [Zope3-dev] [ANN] win32-trunk-pyds
[Stephan Richter] Tim has not been updating them recently. After Jim updated the C code in the adapter lookup code, they were invalid. Adam has picked up Tim's work there. [Benji York] As of 5/1 Tim was still willing to build them (as stated in a message to zope3-dev). I don't think that's changed. If he happened to miss a change requiring a recompile, just drop him a line and I'm sure he'll update them. I'm no longer routinely building, or running, Zope3 on Windows, so I'll indeed only update Zope3 .pyds if/when someone emails me saying that's needed. And right, I'm happy to do so. If Adam is paying more attention to Zope3, and especially if has an automated way to keep his Windows Trunk zipfile release up to date, that's probably better all around. If that is the case, then I should remove the old pyd .zip files from my member page, and plant a link there to Adam's gimmick instead. Adam, do you intend to keep Trunk up to date now? ___ Zope3-dev mailing list Zope3-dev@zope.org Unsub: http://mail.zope.org/mailman/options/zope3-dev/archive%40mail-archive.com
