Followup to "Best of Breed Controllers"

My prior post regarding Best of Breed Controllers got more notice than I had anticipated, I definitely didn't expect the interesting discussion regarding object publishing history it spawned.

But first, some corrections:

• Kevin Dangoor points out that CherryPy allows for computed URL traversal by having the parts of the URL passed into a default function with a function signature like def default(self, other, parts, of path):. On a side-note, I believe David Creemer is using this aspect in his use of Routes integration with CherryPy to some extent.
• Mike Watkins gives a great overview of Quixote on his blog. He also shows how it fits into the categories I mentioned above and points to a hello world web app that again looks similar to the other frameworks.
• Adiran Holovaty notes that Django controllers can be callable's too, and that my example is somewhat misleading regarding the amount of code required for a basic controller. This is because the example I took from the Django documents was from a fairly advanced controller that was doing a lot of work.
• Robert Brewer mentions that CherryPy controllers can be any callable that allows an “exposed” attribute to be set on it, though they tend to be class methods as its easier to hook them into the cherrypy.root handler tree. Also, CherryPy doesn't officially advocate any templating language.

In a way, Phillip J Eby's correction regarding the history could be in the list above. However, it really wasn't my intention to get into a discussion regarding object publishing history. For anyone considering making YAPWF, I'd definitely advocate catching up on lessons learned in the past as it makes no sense to repeat their mistakes. I think in hindsight, a better heading for that section would've been Who didn't do it first as the real intention of the section was so that people wouldn't assume one of the frameworks I mentioned was the first to come up with it.

For those interested in the history of Zope, its predecessor Principia and Bobo, I'd highly suggest reading the above link to Object Publishing along with Phillip Eby's comment and Paul Everitt's response. I've found it all rather fascinating as most of the frameworks I showed looked so similar to Bobo. So nice to know that an old Python ‘adage' I read (probably on some comparison of Python and Ruby) seemed to hold up here. If you give the same task to a dozen Python programmers, the solution is going to look quite similar.
