Old or removed or deleted portal tool or configlet causes problems on reinstall — by Darrell Kingsley — last modified Mar 13, 2014 12:40 PM
When you have added a configlet (or possibly a tool) to a portal and then decided to remove the product or that you didn't need the configlet and so removed it from the product, this causes errors, particularly when you try to install or reinstall other products that contain configlets, as it looks for the configlet in some deep tool registry.

Stay logged in on a Plone site — by Darrell Kingsley — last modified Mar 13, 2014 12:53 PM
The move from Plone 2.5 to 3.x meant you have to use a different way of allowing your site users to remain logged in.
Running Zope/Plone scripts from the command line — by Darrell Kingsley — last modified Mar 13, 2014 12:53 PM
You need a whole special load of stuff to run Plone or Zope scripts for the command line. These centre around getting hold of the portal object from which everything else is available, setting a fake request object so you can traverse around the site and setting a user so you have permission to do whatever it is you want to do. Then at the end you have to commit your transaction and sync the zeoclients.

Create new style portlets and override existing ones — by Darrell Kingsley — last modified Mar 13, 2014 12:57 PM
New style Plone 3/Plone 4 portlets are more powerful and faster than Plone 2 style portlets, but adding news ones and overriding existing ones does look much more complex at first. But like everything Plone, once you've got the hang of it, it's really not too bad.

URL encoding in a script for Plone — by Darrell Kingsley — last modified Mar 13, 2014 01:03 PM
Sometimes you might need a bit of URL encoding in a python script, for example while writing an URL in a text email which is then auto-translated into a link by the mail client. It's not obvious how to do it, but it is easy.
