welcome a bit and that maybe I just need to go off into a dark cave with just me, Zope and an Internet connection for about three months and then emerge an expert. :-)
Dan, Don't get discouraged. <g> You can download and install FreePM or email me privately and I will give you access to the demo site. http://www.freepm.org:8080/freepm_download It is a medical records application. It isn't pretty (I'm not a graphics person) but it does work and it is built with ZClasses. The demo doesn't have the latest changes I made where I finally figured out how to move all of the code into the Product to make upgrading a site easier. But, you can browse through the ZClasses and maybe I can answer a few questions for you. Everything I learned about how to make them work is in the list archives and How-To's. BTW: The only thing I wasn't able to do with ZClasses was get the performance I wanted/expected. I also want to overload a couple of the ZODB classes so that I can create my own audit trails. So, I am moving to a Python based Product. I hope I can accomplish that since products are loaded last. No, it wasn't easy to understand how to write a Python Product, it was easy to 'do'. May I even say that it is simpler than it sounds? But, search the Zope site for 'minimal' there are two How-To's and then look at the code for a couple of the other smaller products like BTreeFolder or CookieCrumbler. Cheers, Tim
