What's the typical conversion from a TALES expression with spaces to a PythonScript argument?
by Simon Bayling 15 Oct '03

15 Oct '03

Hello, How do you convert the spaces in a TALES expression? e.g. <td tal:content="repeat_object/person id">placeholder</td> to <td tal:content="python:container.script_id_converter(repeat_object.??)">pla ceholder</td> At the moment I'm using <td tal:define="tmp repeat_object/person id" tal:content="python:container.script_id_converter(tmp)">placeholder</td> but there must be a nicer way than that (probably a common one I've missed seeing in the Zope Book somewhere) Cheers, Simon Bayling

Problems installing the MySQL drivers
by Florian Lindner 15 Oct '03

15 Oct '03

Hello, I try to install the Zope MySQL drivers, instructions from http://heanet.dl.sourceforge.net/sourceforge/mysql-python/ ZMySQLDA-2.0.8.tar.gz I dowloaded the python driver and the Zope DA from http://sourceforge.net/projects/mysql-python I did a: bastet:~/MySQL-python-0.9.2 # python setup.py build bastet:~/MySQL-python-0.9.2 # python setup.py install (as root) I used my /usr/bin/python to compile it, the same I used to build Zope. All seemed fine. Then I extracted the Zope DA from the Zope directory /opt/Zope2.7 it extracted into ./lib/python/Products/ZMySQLDA/ When I try to startup Zope bastet:/var/zope/bin # ./runzope ------ 2003-10-15T16:07:17 INFO(0) ZServer HTTP server started at Wed Oct 15 16:07:17 2003 Hostname: localhost.localdomain Port: 8080 ------ 2003-10-15T16:07:17 INFO(0) ZServer FTP server started at Wed Oct 15 16:07:17 2003 Hostname: bastet Port: 8021 ------ 2003-10-15T16:07:17 INFO(0) Zope Set effective user to "zope" ------ 2003-10-15T16:07:21 ERROR(200) Zope Could not import Products.ZMySQLDA Traceback (most recent call last): File "/opt/Zope-2.7/lib/python/OFS/Application.py", line 534, in import_product product=__import__(pname, global_dict, global_dict, silly) File "/opt/Zope-2.7/lib/python/Products/ZMySQLDA/__init__.py", line 91, in ? import DA File "/opt/Zope-2.7/lib/python/Products/ZMySQLDA/DA.py", line 92, in ? from db import DB File "/opt/Zope-2.7/lib/python/Products/ZMySQLDA/db.py", line 89, in ? import _mysql ImportError: libmysqlclient_r.so.12: cannot open shared object file: No such file or directory Traceback (most recent call last): File "/opt/Zope-2.7/lib/python/Zope/Startup/run.py", line 27, in ? run() File "/opt/Zope-2.7/lib/python/Zope/Startup/run.py", line 24, in run start_zope(opts.configroot) File "/opt/Zope-2.7/lib/python/Zope/Startup/__init__.py", line 50, in start_zope starter.startZope() File "/opt/Zope-2.7/lib/python/Zope/Startup/__init__.py", line 218, in startZope Zope.startup() File "/opt/Zope-2.7/lib/python/Zope/__init__.py", line 46, in startup _startup() File "/opt/Zope-2.7/lib/python/Zope/App/startup.py", line 47, in startup OFS.Application.import_products() File "/opt/Zope-2.7/lib/python/OFS/Application.py", line 512, in import_products import_product(product_dir, product_name, raise_exc=debug_mode) File "/opt/Zope-2.7/lib/python/OFS/Application.py", line 534, in import_product product=__import__(pname, global_dict, global_dict, silly) File "/opt/Zope-2.7/lib/python/Products/ZMySQLDA/__init__.py", line 91, in ? import DA File "/opt/Zope-2.7/lib/python/Products/ZMySQLDA/DA.py", line 92, in ? from db import DB File "/opt/Zope-2.7/lib/python/Products/ZMySQLDA/db.py", line 89, in ? import _mysql ImportError: libmysqlclient_r.so.12: cannot open shared object file: No such file or directory bastet:/var/zope/bin # What's wrong?

Zope start finished
by Ulla Theiss 15 Oct '03

15 Oct '03

Hello list, we have a local Zope installation on a laptop to present our product. Our problem is, that starting Zope lasts a relative long time and we have no feedback when our product is ready to work. Is there a possiblity to show the user e.g. a message box when zope and the product are ready to work and the user can start the presentation? For example is there a method that can be overwritten in order to do that? Many thanks in advance, Ulla.

Re: [Zope] Connecting to Zope with a Thick Client
by Etienne Labuschagne 15 Oct '03

I know that OSE is very complete and quite stable. On the other hand Twisted seems more Python and less C++, but I don't know how mature it is. It may be that they are not really comparable and that one will be much better suited to what I'm trying to do - will have to inverstigate . . .

FYI: Epoz 0.6 with CSS-Support
by Maik Jablonski 15 Oct '03

15 Oct '03

Hi to all, today I've released Epoz 0.6 - the CSS-Support-Release. If you ever used Epoz, you should upgrade. If not, you should have a look...:) What is Epoz? Epoz is a cross-browser-wysiwyg-editor for Zope/Plone/Silva etc. Epoz can easily be integrated into your own applications too (one line of code). Where can I see a demo? http://mjablonski.freezope.org/epoz/test.html/edit What has changed in 0.6? - Epoz renders now the wysiwyg-textarea with your given css-styles. This gives you a more realistic feeling about the look of your work (esp. in Plone). Many kudos to Ariel Sebbag for the solution to a real problem!!! - Fixed issue for from time to time disabled wysiwyg-areas on Mozilla. Removed EpozTimeOut by a try-catch-poll in order to get Mozilla working in wysiwyg-mode. Many thanks to Guido Wesdorp for this idea!!! - Improved Table-Popup: Now you can insert tables with or without heads. - Added nowrap-style around Epoz-Toolbar so buttons won't break onto two lines. Where can I buy Epoz? Nowhere... Epoz is for free. Epoz is developed for the project e-teaching@university (powered by Bertelsmann-Foundation / Germany) at the University of Bielefeld as contribution to the Zope/Plone-Community and is released under the Zope Public License. Where can I download Epoz? http://zope.org/Members/mjablonski/Epoz/ Hope you like it...:) Cheers, Maik

RE: [Zope] Invalidate RAM cahce manager programatically
by Jim Kutter 15 Oct '03

15 Oct '03

Ok here's what I was doing wrong. What I neglected to mention was that I am also using a ZCatalog to kind of cache SQL results, and facilitate searching. The catalog is what returns the SQL results to the script for rendering. What I discovered was that calling catalog_object doesn't re-catalog the SQL results like I thought it would. I had to uncatalog_object first, then catalog_object to have the changes from the database kick in. I presumed that multiple calls to catalog_object would overwrite the ZCatalog's entry with new data. Thanks mucho for everyone's help. -jim -----Original Message----- From: Jim Kutter Sent: Thursday, October 09, 2003 10:55 AM To: Dan Pierson Cc: zope(a)zope.org Subject: RE: [Zope] Invalidate RAM cahce manager programatically I found the Zcachable_invalidate call yesterday after my first post, but I couldn't get it working properly, and figured it was the wrong way to go.

Hi Chris, Thanks for the response back. I usually post back to the group once I have the answer or solution to my problem but I am cc'ing the list here. You had originally asked me to give you more information on the dates and that I should look at the bobobase_modification_time. I do not know how to look that the bobobase_modification_time so I looked up methods on how to look at that off of some other sites but from what you stated below I do not really need to look it. > No, because it'd be the wrong thing to use in this > case. My question was because > you may already be using it without knowing it, > hence the problems you're having.
