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

Date utility for Zope (V2)
by Brian Sullivan 10 Nov '10

10 Nov '10

I am looking for a standard way (from a python script in Zope) to define and manipulate time intervals for periodic events. I need to define things like every weekday at 8 am, the 2nd day of every month at 8am, every weekday at 8am, 10am and 3pm in addition to easy things like everyday at 1pm. Does such a standard exist - perhaps with a library to manage the conversion to real times? On another forum this http://labix.org/python-dateutil was suggested -- it looks to be close to what I was thinking -- but I am not totally sure how I can use it in Zope (a level of incompetence issue no doubt). Is there something else Zope(not Plone) ready? Or alternately how would I use this in Zope?

Order of Indexes when reindexing
by Sascha Welter 09 Nov '10

09 Nov '10

Hi Zopistas! I have a funny situation here, where aparently the order in which indexes are rebuilt during an object reindex introduces some random error. There are 2 kinds of objects: jobs and documents. Documents are for this example invoices that invoice one or multiple jobs. Each job can be invoiced in zero, one or multiple invoices. Due to modelling the way people work, the link is done from the document to the job, i.e. in the document we store the IDs of jobs that are invoiced. The job can find the documents that it's invoiced in via a Catalog search. Each job needs a "most relevant invoice" date, if the job has 2 invoices, the date of the invoice with the highest amount is the "most relevant" date. That's childs play. It gets put into a DateIndex. The problem appears when reindexing either a job (on editing the job) or when reindexing all the catalog: Apparently sometimes, the "most relevant date" index gets calculated when the "job-to-document" index is still empty. Result is that about 5-10% of "jobs" have an empty value in the "most relevant date" index. What strategies are you following for avoiding one index to depend on another? Or am I doing something wrong and I'm the only one who got a problem which seems to be angled on the order with which indexes are emptied and reindexed? Thanks for any hints! Regards, Sascha
