The word "students"
by Asad Habib 18 Nov '04

18 Nov '04

Is the word "students" a reserved word in Zope? Apparently, I named a list "students" and then tried to populate it with the result set of a query. This variable was never populated and Zope did not generate an error. Also, I tested my query independently through phpMyAdmin and the Z SQL interface and it passed. When I changed the name of this variable from "students" to "studentNames", everything worked. Also, this is the only variable named "students" in my application. Your input would be appreciated. Thanks. - Asad

Stop. ********************************************************************************************************* Later i tried to follow the instructions in the below link to install it. http://mail.zope.org/pipermail/zope/2002-June/116009.html But this time i got a different error message as mentioned below ********************************************************************************************************** >python setup.py install Traceback (most recent call last): File "setup.py", line 36, in ? raise exceptions.RuntimeError,'Python must be linked against -lpthread' RuntimeError: Python must be linked against -lpthread ********************************************************************************************************** Can someone please provide me some suggestion to make this right and get DCOracle2 installed for Oracle 9i.

RE: Left Menu (Frame) on ZMI not displaying (ARGH!!!!)
by Carl Batten 18 Nov '04

18 Nov '04

Paul, I have never experienced the left pane not loading, but I have often experienced it taking a very long time to load. It seems to be Zope's way of telling me that it is time to pack the database. Packing the database always fixes it. Then it gets slower and slower over time as edits swell the database. If you haven't packed your database recently, you might try it. Carl >Well, I moved Data.fs from the working server to the new server (after shutting Zope down >on both of course) and the problem STILL persists!!!! This is really frustrating .. I mean, >it worked fine for 3 days then suddenly doesn't work .. no errors in logs, what the ???? > >ANynody have any last suggestions before I resort to re-installing everything fresh from >source???

Zope startup error msgs
by John Poltorak 18 Nov '04

18 Nov '04

If Zope fails to start up none of its error msgs are recorded in event.log. Is this to be expected and if so how can I record why it has failed? -- John

Problem adding ZClass after upgrade to 2.7
by Anthu Nguyen 18 Nov '04

18 Nov '04

I just recently upgraded from 2.6 to 2.7 (running on Solaris). But now I can't add new ZClass objects anymore. I'm asked to login and then told I don't have permission. Copying, pasting, uploading new versions,etc of these objects is no problem. Any ideas on how to remedy this? TIA, Anthu

Re: Zope Digest, Vol 6, Issue 22

I also had a problem with ZSyncer 0.6 on a Zope 2.6.2 installation and I was attempting to do a sync with another Zope (plone) 2.6.2. I fixed the problem as follows (I can't promise this is a good fix, as it's a quickie but it seems to be OK): Around like 571 replace the code that looks like: full = obj.absolute_url_path() with try: full = obj.absolute_url_path() except: # absolute_url_path and virtual_url_path just don't work # in a apache proxy-vhm-zope situation, apparently. full = re.sub(r'.*?//.*?/',r'/',obj.absolute_url()) Greg Dudek > > > Syncing from A to B doesn't work at all.

acquisition
by Jason Leach 18 Nov '04

18 Nov '04

hi, So I have a cookie crumblier login manager. If I call a page that accesses login manager the macro/ZPT (through acquisition) references all my pages as: www.foo.com/login/mypage and www.foo.com/login/otherpage. I suppose its fry my references like href="mypage" in the Macro/Template. Do I need to fully qualify all the references with href="www.foo.com/mypage"? Jason.

Performance Zope & Caching with Squid
by Gregor Melhorn 18 Nov '04

18 Nov '04

Hello Zope-Users, First: I really don't know much about squid for now. Second: I've got the following problem on Zope Caching: My site has a high number of concurrent, authenticated users, that need to view private content (that's some kind of "worst case", isn't it? *G*). There is some frequently accessed content that may not be viewed by anonymous users, but is static to many authenticated users. Obvious solution would be using a RAM Cache manager, I suppose, so authorization is still done. Wouldn't it be faster to have the content cached by a proxy, taking the load from my ZEO-Clients (that would effectively only serve the same page over and over again)? Is it possible to somehow change the cookie user information that is submitted to Squid, so squid performs an authentication by itself? So I'd declare these (read-only) pages as cacheable, and Squid performs authentication before content is served. Is it possible to use Squid for ssl-encryption? Thanks in advance. Gregor

Re: [Zope] image objects into table via python script

Yes - in a ZPT referencing the image object automagically generates that tag. I was hoping I could get the same result in a python script without any 'gotchas'.

Thanks, I hadn't thought of that - tried it, but still get the error. It is reported as a TALES attribute error but I think that is just what bubbles up from whatever error is generated in the python script when it tries to do: print(item.art_image()) > Finally, you should re-think doing HTML in a script. That's really > what templates are for. You can use scripts for creating the list of > items or doing complex transformations, but actually creating the > HTML is not usually recommended. Yes, I know - unless as some say the TAL gets 'too' complicated or convoluted, in which case one 'should' move that logic to a python script - though perhaps not HTML generation. Anyhow...here is my situation: The number of items returned by a query will vary. So I need to generate a table with a fixed number of columns and a variable number of rows (last row not necessarily full). That is, a 2-D output, not just a 1-D list like in all the TAL 'repeat' examples I've ever seen or done so far. It was something I could figure out how to code in python. It was instant headache to try to code it in TAL. I am doing it with an explicit control variable in python - to know when to end one row and start another - and I don't know how that's possible in TAL. Is it? If someone can give an example in TAL of iterating over a variable number of items and generating a 2-D table with a fixed number of columns that would indeed be a more appropriate solution. thanks, John S. __________________________________ Do you Yahoo!?

PAFlow goes international
by Paolo Bizzarri 18 Nov '04

18 Nov '04

PAFlow is an open source software for document tracking and document management. It is currently being been developed following a series of requirements for the Italian public administration. Until now, PAFlow has been mainly an italian project. Even if it is used in several different public administrations here in Italy, we would love to have it used in an international contest. Also, we would like to take a more "open development" approach to the whole project. As such, we have done a couple of actions: - we have activated the mailing list "paflow-english", as current mailing list are in italian only. You can find it at: http://lists.sourceforge.net/lists/listinfo/paflow-english - we have provided a public CVS for the whole project, that mirrors our internal CVS every night. You can find it at: http://sourceforge.net/cvs/?group_id=7171. The web site for the project (currently in Italian only) is available at www.paflow.it. You can also download and try the latest version from the web site. We will try to provide more material as soon as possible. We are anyway open to input from other people. We really hope this project could be of interest for Zope users, and to find people interested in cooperating with us. Anyway now PAFLow is out in the wild. Regards.
