Arc v' Zope

Writing some basic view objects for the simple Zope 3 todo list.

Some complain that there are too many web frameworks" for Python. I don't.

To continue with the todo application, a new 'skin' needs to be defined and a simple template made.

Getting back to the exploring the todo list application for Zope 3, with a nod to its inspiration.

Linking to David Heinemeier's weblog and assorted thoughts about agile web development.

Phil Windley writes of recent encounters with large development teams who have no running code to show for their efforts. I can barely fathom such a thing.

Another unit test success story to remind myself the merits of testing in the future when I feel too rushed to set up that initial harness.

Adding basic ZMI add / edit support for Todo List and Todo.

Using ZCML to configure the Todo and Todo List classes into the Zope 3 system.

Zope 3 is interface driven and strives to be much lighter in code requirements than Zope 2. This is a look at a trivial todo example.

Zope X3 uses a JavaScript+XML based navigation tree in its default management interface skin. Here's how to make it work in browsers like Safari.

Installing Zope X3 3.0.0, as well as thoughts on what - at its heart - makes the core technologies of Zope still relevant to web development.

Paul Everitt finds an old floppy disk of Zope's predecessor, Principia. This beast waxes nostalgic.

After wrapping up a recent integration project, I start pining for some Zope 3 technologies and remember Five, a project that brings and adapts some core Zope 3 technologies for use in Zope 2 projects.

Today, I started work on bridging two systems together. Both were primarily written by me, but to serve different ends, and both are built on Zope 2.

I took a quick look at a SQL Object Support package for Zope 3 today, and was impressed by seeing Zope 3's adaptation principles in action.

Python is an excellent "solution building" language, great for building applications out of various services and components. But it can ably produce those too.

Zope 2.7 is finally out the door. Joy floods the land.

A look (or really - a guess) at what the Zope 2 roadmap looks like right now.

The core Plone team gets interviewed.

Using keywords to keep loose associations between that which updates data and that which queries it, should both want to use a cache.

I forgot just how big (and wide) a Zope 2 inheritance hierarchy can be...

I started evaluating RevisionManager today. RevisionManager is an unobtrusive CVS front end for basic Zope objects. So far, I'm pretty happy with the results.

A quick glance at various Form / Schema and Validation frameworks and libraries for Python and various Python web frameworks.

I go on and on about my little SQL and LDAP Table Gateways. But there's a particularly good reason...

As storage interaction mechanisms are becoming more abstract in my projects, a Schema Validator pattern has started to emerge as a means of ensuring what I store is in the format desired.

Using Zope's cache management system and third party cache managers can give Zope more room to execute its dynamic code while removing the burden of serving large static content. This can be done without losing any of Zope's excellent content management benefits, and without changing an application that uses stock Zope objects.

Zope 2.7.0b1 was released recently and I'm just now getting my first quick look at it. I'm thinking this...

An early morning reading about ACS 4 prompts thoughts about Zope 3 and the transition strategy that is already setting itself in place.

A look at using Python's pprint module with a logging system (zLOG is used in this example) to dump readable data structures to program logs.

A look at yet another "death of classes" post. I don't think classes are dying, but they have been terribly abused over the past decade. The tide is finally turning to smaller hierarchies and collaborating objects. I share some recent experiences with applying Zope 3 component style patterns to Zope 2 projects.

This week, I apply my RDBMS abstraction patterns to LDAP for delightfully rapid results.

A long post documenting a transition from chasing pure object-relational mapping to componentizing the data manipulation sequence and freeing myself of many headaches in the process.

Yes, it's been quiet lately. I'm buried deep in a project where I'm still (as always) wrestling with the...

This morning, I did a more thorough reading of the design outline that comes with Ape, and I think...

Now with two well designed frameworks that abstract persistence AND work with Zope (Ape 0.6, Modeling 0.9pre4), I can...

Shane Hathaway's APE 0.6 is out. APE (short for Adaptable Persistence) just might offer me the high level object-relational...

I'm still slogging away on multiple projects, trying to bring a big mess of scripts under some more component-like control...

I'm so tired, but thanks to all the daylight we're saving, my internal clock isn't telling me that it's...

A surprise series of events leads to a long-desired leap in architecture on a pair of Zope projects. One of the catalysts was a "From CMF to Zope 3" slide from Tres Seaver stating "Pluggable components are good; configurable components are better." The other catalyst was an application of a massive speedup to a critical piece of business logic in one application that had to be placed in another, only to realize how much the two code bases had forked - all in an area of customer-specific data requirements/configurations. In the course of a few hours, a configurable component solution steps into play to wean us off of the software configuration management difficulties presented by keeping important code in ZODB placed scripts. All this was done by using some common sense component design techniques, a bit of refactoring afforded by moving large scripts into classes, and use of Formulator to describe component configuration schemas. Read on for more details...

But Paul's cautionary articles are very much to the point. Even as the Zope development community is pushing the envelope...
