"double opt-in" or "opt-in with confirmation".
by Brian Sullivan 30 Nov '10

30 Nov '10

I am looking for a strategy or samples (or even just a hint as to the best process) to create an email opt-in strategy in Zope. I am thinking that what you do is use some sort of hash or unique id creation mechanism (based on the email address, time or something else). Based on what I am seeing -- some sort of MD5(not totally sure what that means but I understand there are Python supplied functions to generate it) hash of a combination of the email address and date/time stored and then sent to the user should guarantee that it is unique, can't be auto generated by some bot and should allow verification on http access using the hash in the url? All the potential solutions I am seeing use Python 2.5 + -- the version of Zope I am using is based on Python 2.4.4. Anybody have any ideas or have implemented something like this?

Zope] problem installing Openflow product of zope on LINUX
by smita kamdar 29 Nov '10

29 Nov '10

HI, I want to install OpenFlow so that I can generate & add workflows in my project. Thanks for Your valuable suggestion.But I am specifically told to download & install ‘OpenFlow’ product of zope. Also a file named ‘expression.py’ does not exist in my OpenFlow-1.0.0 folder. My OpenFlow folder shows the following files & directories after installation – [test@test openflow-1.0.0]$ pwd /opt/zope/lib/python/Products/openflow-1.0.0 [test@test openflow-1.0.0]$ ls acinclude.m4 build-aux config.status udatapath debian m4 aclocal.m4 configure doc README.kernel autom4te.cache README.hwtables Makefile.am config.h configure.ac include bin config.h.in stamp-h1 controller INSTALL var boot.sh Makefile.in ChangeLog config.log sbin soexpand.pl COPYING tests utilities Lib share regress README third-party secchan Makefile I have downloaded openflow from http://www.openflowswitch.org/wp/downloads/. I think I have downloaded the wrong ‘OpenFlow’ software. >From where should I download ‘Openflow-1.1.0’ product that ships well with Zope2.11?? Thanks a lot!!

problem installing Openflow product of zope on LINUX
by smita kamdar 28 Nov '10

28 Nov '10

Hi, I am supposed to set up development environment for a project. & for that I have already installed Zope-2.11.4, Python-2.4.4, Egenix-2.0.6, Postgresql-7.4.13, & Psycopg-1.1.6 on a RedHat LINUX box. Now I need to install OpenFlow-1.1.0 in the Products directory of Zope. I tried installing OpenFlow source tar ball by the following instructions – ./configure Make Sudo make install All of the above commands worked successfully. But still I am not able to see the openflow product on the Zope Management Interface Screen. Can you please suggest something? It’s really urgent. Am I missing any steps while installing OpenFlow? Please Help me. Regards, Smita

Clock server
by Brian Sullivan 26 Nov '10

26 Nov '10

I am about to put the clock server function of Zope to work and am thinking about what happens if the server fires its request while a request is already in progress. Is there some sort of built in lock preventing this from happening? If not what is the most straightforward failsafe way to implement something that would lock on entry and unlock on exit?

AttributeError: @@plone
by Eddy Ilg 24 Nov '10

24 Nov '10

Dear Zope Users, we are trying to get an old plone application to work and keep getting the error message "AttributeError: @@plone". Some posts suggested it might be a zope/plone conflict, that's why we are also posting this to the zope list. The versions we are using are: Python: old=2.4.4 <-> new=2.4.6 Zope: old=2.9.6 <-> new=2.9.6 Plone: old=2.5.3 <-> new=2.5.3 We have already tried the migration assistant, but no luck. We moved the application by simply copying the instance directory and also tried setting up a new instance with plone 2.5.3 and installing the products manually. Both yield the same error. Is there anything special to consider when copying an instance from one server to another? The user permissions are set to the zope user. The complete traceback is as follows: ------------------------------------------------- 2010-11-24T15:45:32 ERROR root Exception while rendering an error message Traceback (most recent call last):

Zope directory in the Cloud

Is it possible to use some sort of Cloud service as a "directory" in Zope 2 (I guess what I am asking for is some sort of product to do this)?

urllib.urlopen inside a python-script? alternatives?
by stephan0h＠gmx.net 15 Nov '10

15 Nov '10

Hello, I'm trying to use facebook's single-sign-on mechanism with zope and querying account information for logged in facebook-users from within zope. For this I need to send url-requests from my zope-server to the facebook-servers and read the response. I tried to test the concept with a python-script: ############## import urllib cookie= request["fbs_" + "<the application id>"] args=dict(map(lambda x:x.split('='),cookie.split('&'))) url="https://graph.facebook.com/me?access_token="+args['access_token'] file = urllib.urlopen(url) resp=file.read() file.close() return args,url,resp ############## When running this an authentication-window pops up - and subsequently tells me: ----------- Error Type: Unauthorized Error Value: You are not allowed to access 'urlopen' in this context ----------- So the problem is with opening the external-url I suppose ... What's the Zope-way of doing this? - how can I tell it to get read information of another URL? thanks, stephan

Problem with browser:resourceDirectory in Zope-2.13.0 (final): ComponentLookupError

Hi, I have a problem with using browser:resourceDirectory in ZCML with the latest Zope-2.13.0 (final) from 05-11-2010.
