Re: [Zope3-Users] Resource lookup by resource name
Hi Andreas,
I had a requirement where I needed to manage the resource directories
dynamically. So I developed some of following code. I guess this might
be of help.
Functions to work with browser resources at run time
#python imports
import logging
# zope imports
from zope.publisher.interfaces.browser import IDefaultBrowserLayer
from zope.interface import Interface
from zope.component.globalregistry import getGlobalSiteManager
from zope.app.publisher.browser.resourcemeta import (CheckerPublic,
DirectoryResourceFactory,
allowed_names, NamesChecker )
def registerResourceDirectory(name, resourcedir,
layer=IDefaultBrowserLayer,
permission='zope.Public'):
This function registers a resource directory with global registry
logging.info('Registering %s as %s' , resourcedir, name)
if permission == 'zope.Public':
permission = CheckerPublic
checker = NamesChecker(allowed_names + ('__getitem__', 'get'),
permission)
factory = DirectoryResourceFactory(resourcedir, checker, name)
gsm = getGlobalSiteManager()
gsm.registerAdapter(factory, (layer,), Interface, name)
return True
def unregisterResourceDirectory(name,
layer=IDefaultBrowserLayer):
logging.info('Removing %s' , name)
gsm = getGlobalSiteManager()
gsm.registerAdapter(None, (layer,), Interface, name)
return True

Re: [Zope3-Users] Multi platform dev environment
Hi Edward, Philipp's book (2nd edition which I use) is written with Zope 3.3 in mind. This was released few years ago. Since then, there has been quite a lot of evolution in terms of how zope 3 is organized, how instances are created etc. - People now use zc.buildout commonly for creating instances and distributing applications. - zopeproject is one recipe for zc.buildout way of doing things. - People in the zope 3 development community are generally using zc.buildout - zopeproject based buildouts I believe can be distributed in its entirety. They contain all the eggs necessary for your application. I for myself, have continued to stick with the Zope 3.3.1 for this long as Philipp's book covered it in quite detail and migrating to the newer ways of organizing applications would require some work.

Re: [Zope3-Users] Multi platform dev environment
Hello, I have been using Zope 3 primarily on Windows platforms for last 2.5 years. This is what I do for the typical setup: - Install Python 2.4.4 - Install Python for Windows extensions for Python 2.4 - Install Zope 3.3.1 (the binary installer) - Go to C:\Python24\Scripts - Use mkzopeinstance script to make a zope instance - Checkout my application packages into the zope instance - Run my application Using the binary installers for everything works fine for me. Apart from these, I use some more packages: - ReportLab - Python Imaging Library - z3c.rml - etc. My SVN repository consists of my application package only. I don't check in the zope instance to SVN. After checking out the application package in my zope instance, I need to copy the application-configure.zcml into zope instance's etc\package-include directory. The zope 3.3.1 instances work perfectly as Windows services out of the box. At times I experimented with virtualenv, and grok. But haven't been able to stabilze their workflows on Windows so far.

Re: [Zope3-Users] Wiki proposal
Hello, I had seen a site new.zope.org coming up sometime back which was using Sphinx for the documentation of Zope 3. Though there was never a public announcement of the website on this mailing list. The approach seemed promising. It somehow supported integration of work from multiple contributers from different websites. For example, z3c.form documentation was integrated from Paul Cauldner's website. Unfortunately today it seems that the website has gone somewhere else and I don't know where it is. Further digging shows that its now accessible at http://docs.zope.org/. I think I missed out when this change happened. There seems to be another thing coming up (which I noticed today). http://docs.zope.org/zopetoolkit/ . Seems like zope 3 is going to be called zope toolkit from 3.5 onwards. I have accidentally discovered it today. This site is also developed in Sphinx. I am not sure what is the process for contributing to these documentation websites Overall, to me it seems that Sphinx based documentation is better compared to a Wiki based documentation. One can focus on writing documentation using simple text editors. The http://www.zope.org/ website talks about becoming a contributor, but thats focused on becoming a developer.

Remember authentication and authorization are two different things. I'm not really sure.

[Zope3-Users] A question regarding zope generations
Hi, I have a small doubt regarding zope3 generations. In the current way of doing things: - one should first put a dummy schema manager, restart the zope, so that a generation 0 is assigned to the application. - one should then put the actual site specific schema manager which would use the evolution scripts from this point onwards in development. I essentially have a web based application product and the users have no idea of zope and python as such. The product is shipped to them, the installer installs the whole zope 3 instances and services by itself and starts them. For the upgrade case, the installer (NSIS based) stops existing zope 3 services (Win32), replaces the software and then restarts the services. Unfortunately, I didn't have setup the dummy schema manager in the earlier version of the product. Now that I need to send an upgrade, I am facing the dilemma of how to setup the evolution scripts. As doing that would require doing more complicated processing in the installer. (stop the services, put code for dummy schema manager, start the services, ensure that database schema generation has been setup for the product, stop the service again, put the new code and the regular schema manager, start the service again). This would complicate my installer a bit more. Its already quite complicated. I don't know if this is quite a common use case scenario for zope based applications. I am sure its not relevant for applications which are based on a website and managed by an expert, but for products with zope built-inside, may be this could be of use. As of now, I am thinking of a following solution. For the current upgrade, I will have some code which will automatically evolve the existing installation during startup (i.e. DatabaseOpenedEvent) and actually assign a generation number in the root[generations_key]['product_name'] key.

Hi,
apart from Session Credentials, I would also have Zope Realm

For the normal browser based access, the session credentials plugin
does the work.
For XMLRPC access, I fall back on 'Zope Realm Basic-Auth'.
The URL for XMLRPC server proxy would include login and password
information like:
objProxy = xmlrpclib.Server('http://login:[EMAIL

I've gone back into the 22auth example of Phillip von Weitershausen's

made some simple modifications to elucidate my question in a simple
environment
which I describe here:
created a zope 3 instance
created a site named wcsite
created a folder named rfolder
created a recipe named r1
created a recipe named r2
configured a PAU (at the wcsite level)

Access using a browser works fine. If I attempt to access an object
that an unauthenticated
user has no access to, I'm presented with a login page and after
logging in, I acquire and retain access
until I logout. That's good.
I modified Phillip's example python code worldcookery/xmlrpc/
recipe.py to authenticate using
a user=u1 and password=p1 (or so I think, hence my problem). That
program is shown below.
To test:
First, in a browser I log in a manager and I edit the wcsite roles
and permissions to grant the Site Manager role to All Users.
then run
displayandedit.py http://sasa.local:8080/wcsite/rfolder/r1
This works fine, so I'm able to locate and access and edit the recipe
data
Next, (using a browser and logged in as the site manager)
I edit the wcsite roles and permissions to UNSET the Site Manager
role to All Users and
grant the Visitor of the WorldCookery website role to All Users.
Further, I edit wcsite/rfolder/r1 to grant the Site Manager role to
user u1
So, the user r1 can read everything on the site but can only edit
wcsite/rfolder/r1
Now, I rerun displayandedit.py http://sasa.local:8080/wcsite/rfolder/r1
and get an Unauthorized error:
xmlrpclib.ProtocolError: ProtocolError for sasa.local:8080/wcsite/
rfolder/r1: 401 Unauthorized

Couldn't find any particular event that is sent at that time. But looking
at: zope.app.main.main, i tried:
from twisted.internet import reactor
def shutdown():
#shutdown code here.
pass
reactor.addSystemEventTrigger('before',
'shutdown', shutdown)
and this seems to work. (did this under an event handler for
DatabaseOpenedWithRootEvent).
Just want to confirm, is it the right way to do, or there is some better way
to do things?
