That seems to be the problem, I find ZClasses to fill a role for
intermediate skill level developers to create rich objects and
applications. The replacement at this difficulty level hasn't appeared
yet. My impression is that ZClasses will continue in Zope 2.x, but it
hasn't been enhanced or touched at all. The ZClasses implementation
seems to be solid. There are shortcomings with ZClasses when you try to
do too much with them. Some of the Zope 2 books have nice examples are
how and what you can do with ZClasses.
That said, I picked up Stephen Richter's book on Zope 3, very nicely
done... Zope 3 seems to be maturing pretty fast, and some/most of the
new features have been adapted to the older Zope 2 architecture (a
project called Five). If you're going to make a large investment in
time... and you're just getting started, I'd pick up this book, and see
if you can handle the difficulty level of Zope 3, at this point. Zope 3
technologies seem to be the New Way. Although advanced, Zope 3 seems
to be the result of a lot of self-examination of the triumphs and
mistakes of Zope 2... a few things I picked out an re-thought
organization scheme of naming, libraries, etc., the use of
interfaces/contracts Generally cleaner and more pythonic, allowing
much more power and flexibility... removing much of the mystery of Zope
2 inner workings and naming conventions.
As for DTML, the old way, DTML is a tag-based way to create web
interfaces, similar to CFML, PHP, ASP... inline tagging around and
within the HTML. The new way, is markedly different, and difficult to
get your head around at first, called ZPT (Zope Page Templates). ZPT
uses XML and an attribute system to embed commands in an HTML page,
without ruining your ability to use WYSIWYG editors like Dreamweaver,
etc. ZPT is highly regarded here on this list, and probably will win
out in the end. But there are enough DMTL folks, that DTML will be in
Zope 3 until ZPT takes over.
There is a Zope 3 mailing list, that might be helpful.
Just my observations and impressions,

Thanks a million... it works great...
but when you said that ZClasses and DTML are the old way... what is
the new way... I just started using Zope so I not quiet up to date...
would you mind fill me in so I could look it up?

Hey,
As you'll hear shortly, ZClasses DTML are the old way to do
things, and are not highly recommended, at this point. Having
said that, I've had success using them.
To Add a ZClass into anything folderish, I've used...
dtml-call
RESPONSE.redirect('manage_addProduct/WWAudioClip/WWAudioClip_factory')
where WWAudioClip was the name of the Product and its ZClass
I place this in a DTML Method that is at the point I wish the
ZClass object to be created, a target if you wish. Works fine.
This will call the Add method in your ZClass.
To Add a regular file object somewhere, I've used..
dtml-call this().manage_addFile(File_object_ID,
File_object_contents, File_object_title, content_type='audio/mpeg')
Parameters Zope ID to be set, Contents (string, whatever), and
Zope Title, and mime-type (optional)
Google Zope manage_addFile for more info
HTH,
Jon

I want to create a empty file in a ZClass object when I first
created the ZClass object. How do I do that using DTML??
