Best described as a "web Application Server for Py Thon".
This Wi Ki is in ZWiki, which runs on ZoPe. Running on zope-space that I'm renting (not dedicated hardware).
Supports a text format called Structured Text.
A key product for Zope is the Zope CMF.
I've been unhappy with the zope books I've read/browsed. Probably better off with the [[http://www.zope.org/Documentation/Books/ZDG/current/ |developer's guide]] Jeffrey PShell recommendations (Jul'03):
I try to do a lot of "Product" based development, and I strive to do smaller components with a clean inheritance model. I think they key is just doing smart Python development. Or just smart OOP development, meaning - smaller classes, lots of collaborators. My primary critique of Zope 2 has long been its inheritance tree mess. Zope 3 aims to fix this.
Since Products are written in clean Python, they're a bit easier to do unit tests. Instead of testing the web side, you test the Model (or at least, the Model parts), preferably by aping the Controller parts (the methods that will interact with web forms). The CMF has a large body of unit tests, none of which is dependent on a web setup or even a persistent ZODB connection. It takes some work to set up a test harness, but it can be done. There should be enough examples floating through the Zope and CMF core to provide examples of how to do that.
For testing web stuff, I know they've come up with some Functional Tests for Zope 3. Richard Jones has released Web Unit (I believe) that can set up web requests and test responses.
ZPT is a heavily established Zope 2 technology. It's been in the core since Zope 2.4 and works great. I love it. I can't imagine any other way of templating. (Template System)
Formulator product (does this work happily with SQL databases?)
I would recommend avoiding ZClasses. I'd also get familiar with the OFS package, particularly the differences between OFS.Simple Item.Item (not persistent) and OFS.Simple Item.Simple Item (persistent); learn Object Manager; learn the classes that make up a Folder; and become familiar with Class Security Info (should be documented in the Zope Developers Guide). This is useful even for non-CMS related stuff. I'm making applications now out of fairly simple persistent objects that load all their page templates off of the file system (out of the product) instead of the ZODB. The objects in question are the View/Controller pair of the application and then talk to other classes and objects inside the Product to do validation, LDAP communication, etc. In total - there are five objects that are put into the ZODB that make the application work.
Docs to help learn:
the Zope Book, available in print and in free HTML. Seems a little content-mgmt focused to me
links to intro dev pieces
process recommendations - stay away from the ZMI for any real development.
Jeffrey PShell on the ZoPe inheritance tree
Mar'02 tutorial on building "job list/board" app with Zope3 - business classes vs ZPT, etc.
Basic intro/weird notes:
- strange restriction on spacing for 'dtml-let' - 'dtml-let value = "expression"' does not work, but 'dtml-let value="expression"' works fine
One of the big questions when using Zope as an application server instead of just a content management system is which kind of custom code to use: [[http://www.google.com/search?q=zope+products+%22external+methods%22+zclasses+%22python+scripts%22&hl=en&lr=&ie=UTF-8&oe=utf-8&start=0&sa=N |search]]
Python Script-s: can only use a subset of python libraries
ZClass-es - see Death to zClasses vs this note on using them as starting point
Products - use a minimal facade if appropriate
External Method-s: gets context information in an obscure and often confusing way (intro )
SQL interaction (using an RDBMS instead of ZODB)
Ian Bicking isn't happy with it
