[Zope3-Users] Principal annotations
Chapter 27 of the Zope 3 book and the docstring for IPrincipal in Zope 3.2 both suggest Zope has the ability to provide a browser view of principal annotations. That would be a really great bit of functionality to have! Unfortunately, AFAICT, the system doesn't work at all in Zope 3.2. The Zope 3 book says you have to create an Authentication Service, but no such thing exists anymore. Instead, I created Pluggable Authentication Utility and put a principal folder inside it. But principals created this way are InternalPrincipal objects which do not implement IPrincipal, so they don't have the extra view I registered. I could find no other way to visit a user object in the management interface. Therefore, views of IPrincipal are currently never used. Was this an accident? Did it work at one time? Are there plans to make principal annotation views work again? And how can I edit user annotations in the meanwhile?

[Zope3-Users] Database access problem from form support Class
Zope-3.2.0: I have a MySQL database Utility installed that works fine
via its Test tab, via an SQL Script, and with that script called from a
page template. I want to to use a simple query from a class that
supports a form in a context that has nothing to do with the database.
The code I have tried looks like this:
from zope.app.rdb import queryForResults
from zope.app.rdb.interfaces import IZopeDatabaseAdapter
class EditRoles:
This class reads a form data and updates Permissions
def getPrincipals(self):
try:
connection = zapi.getUtility(IZopeDatabaseAdapter, 'mysql')
except KeyError:
raise AttributeError(The database connection '%s' cannot be
found. % ('mysql'))
query = select * from z3users
result = queryForResults(connection, query)
And when I try to invoke the form I get this error
File /usr/local/Zope320i/lib/python/cefsite/browser/editroles.py,
line 47, in getPrincipals
result = queryForResults(connection, query)
File
/home/ceford/temp/Zope-3.2.0/build/lib.linux-i686-2.4/zope/app/rdb/__init__.py,
line 401, in queryForResults
cursor = conn.cursor()
AttributeError: 'MySQLdbAdapter' object has no attribute 'cursor'
Can anyone suggest what I might be missing or suggest another way of
accessing the database?

[Zope3-Users] How to begin?
Hello to everyone on zope3-users! I have a task of developing a web application bye the end of September, thus giving me a roughly half a year window to learn Zope3 and develop at least semi usable application. I took the time and browsed most of the available Python web frameworks, and narrowed it down to Zope3 and Django (possibly TG). I mostly decided to go with Zope3 because it looks more like a complete and homogeneous product, although still rather unfinished. Django sure does look quite simpler with a less steep learning curve, but since I have a time to spare, and I want to invest it in learning a good web framework, Zope3 seems like a way to go. Those who think otherwise, say so, it's still not late to go the other way :). My first goal is to develop a simple encyclopedia-like web page, with a page for adding content, one for searching inserted entries and a hierarchical listing of inserted entries. Ofcourse, some basic user authentication is needed, but nothing fancy. So, is there a documentation/book/HOWTO anything targeted for us beginners that step by step explains how to build a simple web site? Currently I'm stuck with Zope3Book, but I can't quite make heads from tails :(. So, what am I to do to get myself started towards developing my application? Is there somewhere a nice introduction beginner-level text that explains Zope3 fundamental concepts and some simple things you can do with it? I would hate myself if I had to give up on Zope3 just because a lack of documentation :(.

I was just wondering whether I need to buy Philipp von Weitershausen's book in addition to the Stephan Richter book I already have. On Amazon it looks like it has a more example-based approach.

Re: [Zope3-Users] Database access problem from form support Class
To answer my own question for the record, the query call I had that
looked like this:
result = queryForResults(connection, query)
should have looked like this:
result = queryForResults(connection(), query)
However, it would be helpful to know whether calling the database
adapter utility directly has hidden implications - the thread safety
field of IManageableZopeDatabaseAdapter returned 0 (Threads may not
share the module) and I don't know what to do about it, if anything.

This is just work for you, but you could put up a list mapping recipe description to thread. But then others could help distill and annotate the recipes. On the question of where to put it, I have a heretical suggestion: plone.org. Plone developers are trying to understand Zope 3.

Re: [Zope3-Users] How to begin?
In comparison to the cost of six months of your time the books are cheap! I refer to Phillip von Weiterhausen's book a lot, and when I don't understand something I see what Stephan Richter's book has to say. They are both good, even though a little behind the current Zope 3 version. You will soon outgrow the very short on-line tutorials. I find that problems arise when I want to do something that isn't in the books and I have to use the Introspector, read the source code or search the mailing archives. This week I spent an entire day trying to work out how to do something that turned out to be three lines of code, and another day on something that was effectively similar. Very satisfying when it all works though! Cliff Karlo Lozovina wrote: Hello to everyone on zope3-users!
