Plone Conference 2009 – Hardening Plone

kc — Thu, 29 Oct 2009 14:17:38 +0000

This year I’m attending the Plone Conference 2009 in Budapest. Today is the second day and as always with Plone conferences the vibe is great and it’s interesting to see the different talks.

Together with my collegue Kees Hink we gave a presentation about Hardening Plone.

For a customer who needed a DMS to exchange documents with third parties we hardened the Plone stack. Several highlights of the hardening part are modifcations in the OS,� two technical audits, a process audit and adding some extra products in Plone. Here’s is the recorded stream of the presentation: http://www.ustream.tv/recorded/2446265. Here are the slides:

Zope Formlib cancel button

kc — Tue, 20 Jan 2009 10:10:44 +0000

For a Zope FormLib based form I wanted a ‘Cancel’ button. I tried some googling but couldn’t find any info on it. Here it is, it isn’t so hard:

First do some imports:

from plone.app.form.validators import null_validator
from Products.statusmessages.interfaces import IStatusMessage

The cancel function:

@form.action(“Cancel”, validator=null_validator)
def action_cancel(self, action, data):
….context = aq_inner(self.context)

….IStatusMessage(self.request).addStatusMessage(_(‘Cancelled’), type=’info’)

….self.request.response.redirect(\
….context.absolute_url()+’/@@mypage’)

nb. wordpress messes with the indentation, hence the dots. time for a code mark-up plugin….

KSS, client action on server

kc — Tue, 13 Jan 2009 16:52:36 +0000

I’m using KSS in Plone to ajaxify user interface actions. When you’ve got a server-side KSS method and would like to call a client action, here’s how it is done:

self.commands.addCommand(‘alert’, ‘.dummy-selector, message=’I'm called from the server!’)

self.commands.addCommand(‘myKssAction’, ‘my-selector’, param_1=”, param_n=”)

This way you can do necessary things (like storing data from a form), update the info on the page and using the above to call a Jquery function to do fancy style effects.

Simple as that!
