[Zope-PTK] PTK - Putting it all together

Greetings Zope-PTKists -

I need help understanding how to make this leap:

1. I can successfully install the PTK (ie, the
installed products PTKBase and PTKDemo plus
the [no adjective] product DemoPortal) and
make a portal with them. No problem.

2. Although the PTK seems to do much of what
I want, I'm going to have to make several
mods/additions. It is completely beyond me
(at the moment) how it is intended that I
take the PTK pieces and make a portal look
and act the way that I want.

What I think I know:
o I should NOT be customizing DemoPortal [.per

on 26 Feb 2000]
o I should make my own equivalent of DemoPortal
that uses PTKBase (and PTKDemo?) to do what
I need. But how?

I've looked at everything I can find (documents, HowTo's, mailing list
archives) but there is something missing for me. Maybe I could write a
HowTo if I could only figure out how PTK is intended to be used.

Note: This is not a question about understanding the smaller pieces such as
Python, HTML, OO, etc. Rather, it is about a larger understanding. I guess
my question could be restated as:

Given that I can successfully install
and run Zope/PTK/ZServer, how do I take
the PTK and make *my* site from it?

Dazed and Wandering,

Re: [Zope-PTK] PTK - Putting it all together [In reply to]

This is a great question. I'd like to add a bit to it:

I'd assume that to create a new portal type, you'd inherit from the classes that
"Control_Panel/Products/DemoPortal/Portal" inherited from. If you look at it's base
classes, they are ZObject, _ZClass_for_DemoPortalBase, and
_ZClass_for_PortalObjectBase. Since the _ZClass_for* classes aren't in python
anywhere, and they don't show up on the list of classes to inherit from (for a new
ZClass), then where are they defined, and how can they be used?

I can see that they must be derived from DemoPortalBase and PortalObjectBase, but
don't know how.

Thanks,
-Paul

The "_ZClass_for_*" classes are "shims", created when the corresponding Python
classes are registered as base classes by their products (see the
registerBaseClass() method in $ZOPE_HOME/lib/python/App/ProductContext.py). You
can, in essence, ignore them, and imagine that the ZClass which you make is
derived directly from the equivalent Python base class.
