migrate zclass to disk product
by Lee Harr 24 Jan '03

24 Jan '03

Hi; Anyone have any pointers for migrating a product from zclass to disk-based? I did some googling (with no success), and I am ready to do some experimentation, but I think I would rather hear/read from someone who has tried this before I start hacking things up. My best thought so far is just to hide the ZClass (Make its "Add list name" a blank string) then create a new disk product which takes over the "Add list name". Does that sound like the best plan? Is this going to cause confusion? What about meta_type conflict? Is it possible for a new product to take over and actually be the class for those already created instances? _________________________________________________________________ Protect your PC - get McAfee.com VirusScan Online http://clinic.mcafee.com/clinic/ibuy/campaign.asp?cid=3963

Accessing imported module function
by Stacy Roberts 24 Jan '03

24 Jan '03

I am in the process of developing a Python product for Zope. I have created several container (folderish) objects, and have come across a problem when two objects can recursively contain each other. For example, I will explain 3 of my modules: In module CITATION.py, I have the following import statement. This should place this module into my sys.modules dictionary. import CITEINFO class CITATION(Folder): <all the class stuff here> add_citeinfo=CITEINFO.add_citeinfo In module CITEINFO.py import LWORKCIT class CITEINFO(Folder) <all the class stuff here> def add_citeinfo(self, ..., ...): <function statements here> In module LWORKCIT.py class LWORKCIT(Folder) def add_lworkcit(self, ..., ...): <function statements here> This is where my problem lies. In the class statements, I need to gain access to the CITEINFO.py modules add_citeinfo function. The CITEINFO.py module exists in the sys.modules and I can retireve it with the following statement: module = sys.modules 'Products.METADATA.CITEINFO'] However, I do not know how to gain a reference to the add_citeinfo function. Inside my 'def add_lworkcit()' function, I make the follwoing call: withIt.manage_addProduct['METADATA'].add_citeinfo('citeinfo') It appears the add_citeinfo defined in the CITATION.py module is called (since I am unable to define a variable add_citeinfo in my LWORKCIT class. My 'citeinfo' object is added to Zope, but in the wrong namespace. 'withIt' is the LWORKCIT namespace I want the 'citeinfo' object created in. It seems to ignore this and create a citeinfo object in the CITATION object. If further information, explanation, or code is needed for someone to provide me with a little help, please ask and I will elaborate. Any insight into a solution would be greatly appreciated. Thank you in advance. __________________________________________________ Do you Yahoo!? Yahoo! Mail Plus - Powerful. Affordable. Sign up now. http://mailplus.yahoo.com

all work lost?
by Gerhard Venter 24 Jan '03

24 Jan '03

Hi We have a designer who has been trying to make our Zope/Plone test site look unique. She has done something that caused some of the Plone icons go missing. I could not fathom how to get it back, so I installed the Bubble Blue icon set from the Plone website, thinking it may replace any missing icons. The instructions said restart Zope, which I did. After the restart Zope reverted to how it was directly after it was installed (SuSE 8.1 RPM). Even the superuser password was back to the default, and all our work is missing. Or can it be retrieved?

OK, I have learned that ZPublisher is not a Zope product like CMF, and I have it in my filesystem where you said it was. I list the whole output at the end of this message. Thanks for your help.

problems for Zope Installation
by Cathy Nouvet 23 Jan '03

23 Jan '03

Hello, We are trying to install zope2.6 on Solaris 6.4.1. So we took the sources of zope but we could not reach the complete installation. We have downloaded the 2.1.3 version of Python as recommended for zope 2.6. After executing the instructions make and make install, we tried to execute the script w_pcgi.py. And when we launch the application (command "start"), there is a problem of linking libraries. We get this kind of error : Traceback (most recent call last): File "/usr/local/packages/zope/z2.py", line 247, in ? import os, sys, getopt, codecs, string File "/usr/local/lib/python2.1/codecs.py", line 10, in ? import struct,types,__builtin__ ImportError: No module named struct But codecs.py is a python library and so I don't understand. Could you please try to help us. Thank you Cathy and Damien

Non-persistent ZClasses?
by John Coleman 23 Jan '03

23 Jan '03

I am trying to create non-persistent ZClasses. I have seen no examples of this anywhere in the online Zope realm, but I have seen several references to "non-persistent wrapper classes," but no one seems to be able to provide an example. I could be going about my project incorrectly, but this really seems to be the best approach. Is anyone out there familiar with creating these and can give me some examples of constructors (python preferred, but will take whatever you have at this point!) and adding instances programmatically?

Database Adapter Madness
by Daniel Jackson 23 Jan '03

23 Jan '03

I'm writing a ZClass for a generic SQL table editor. It detects the format of the table, and generates a sortable table with add/edit/delete functions. The ZClass itself is tied to a Database Adaptor that has to be hardcoded to connect to a certian database. This is bad, I need each instance to point to a different database. I cannot find any way to change what database the DA connects to in python or by any other method. If you change the connection string, it affects all of the instances of the zClass. I'm at a loss for ideas on how to do this properly. Right now I have a Psycopg DA inside of the ZClass. Anyone have any hints?

Newbie adding users problems to Zope and Plone
by Sam Hunting 23 Jan '03

23 Jan '03

In my acl_users folder, there is only me: admin As admin, I have added several users: jack, etc. However, these users do not show up in the /acl_users folder at the contents tab. Yet, if I add one (say, "jack") I get the message: A user with the specified name already exists So if they exist, why aren't they in the folder? My second question: How the heck to I join a plone site? And how the heck do I add members to it?
