• Software Product: Zope MySQL Database Adapter, by "mordred"

  "mordred" has released an update to the MySQL Database Adapter, by Michel Pelletier (Portland). This release is 1.1.4, and fixes one bug:

  • Fixed a bug that caused Zope to fail on selecting aggregate functions such as select max(number) from table

• Software Product: ZWiki, by "simon"

  ZWiki is a Wiki web for Zope. Zope and Wiki are a good combination. Wiki assumes that, in general, users are trustworthy. Zope, with it's security and transaction history, makes it easy to trust users.

  ZWiki is a sort of anarchic collaborative authoring system. This version, 0.5, streamlines the default pages and UI, and disables the experimental catalog support. This release is intended to be immediately usable out of the box.

Zope.org items

• How-To: Changing Base Classes for a ZClass, by "AlexR"

  When you create a ZClass, you are given an opportunity to chose which classes it will inherit from. Since ZClasses are often used for rapid prototyping, you will not always select the correct classes the first time. It is quite a lot of work to create a new set of classes with the correct bases and to move all the contents into them from the old classes. Armed with this How-To, you will be able to change the base classes of a ZClass in-place!

• How-To: Serve PHP/Perl within Zope, by "Mamey"

  "As you migrate your site to Zope, you may want to embed a previously created PHP or Perl directory tree within Zope. Or perhaps you found a nifty web application that is coded in PHP/Perl and want to serve it within your Zope site." This is a bit more advanced than simply rewriting certain URLs to be served by a different server. This How-To will actually allow you to embed the external content in dynamic Zope pages.
