[ZDP] BackTalk to Document Zope Developer's Guide (2.4 edition)/Components and Interfaces
Tue, 03 Dec 2002 01:06:46 -0500
A comment to the paragraph below was recently added via http://www.zope.org/Documentation/Books/ZDG/current/ComponentsAndInterfaces.stx#2-4
Here is a very simple component that says hello. Like all components,
this one generally consists of two pieces, an interface, and an
from Interface import Base
""" The Hello interface provides greetings. """
def hello(self, name):
""" Say hello to the name """
__implements__ = Hello
def hello(self, name):
return "hello %s!" % name

This information and these sorts of examples as presented here by themselves are all but useless to someone
very new to Zope development. Where do these classes go? How do I install them in Zope? How do you
instantiate the classes? How do you access the instantiations? How can I experiment with this code? You seem
to be presenting all the high-level information without any practical information on how you actually put it
to use. The equivalent would be a beginner's book on Python that assumed you would read the source code for
the interpreter to discover how to invoke it. It seems to me there is a large gap between what you would
learn from the Zope Book and what you need to make use of the information presented here.

I must say I have to agree with Chris.
A few days ago I picked up a PHP book, and in 20 minutes I was up and running with my first PHP code
I'm keen to choose Zope because I've been using Python for while but all this documentation is so nebulous!
I've been reading for days and am still totally vague as to how to get even something elementary happening.
I know there are fabulous people behind Zope and Python. I wish they could hear comments such as those of

I'm sure you were up and running quickly with PHP. But it's likely that you could have been up and running in
Zope as well in the same amount of time by reading the Zope Book. My advice is to not read this guide until
you've thoroughly read the Zope Book and done a little Zope development.
Zope is loosely the equivalent of PHP, Apache, and Oracle wrapped up into a single piece of software, so it
makes sense that it would take more time to grok than straight PHP. That said, there is a gap between the
Zope Book and this guide. It's likely that that gap will need to be filled by 3rd-party published books.

New developers can be attracted to hacking code, by allowing them to see the key points of technology are.
With this example as many other ones, -> zope book, web,
there is alot of information missing, as one can learn from inferred data from other places. This just sucks.
I love python, because it is consice, to the point,
with this stuff, its just superfrustrating. very many people i know gave up, because they wanted all the
details, and all they were given is a gobs of vague ideas, and some code that did not relate, as in between
examples, so it was hard to make out what the hell is going on.
