How do I integrate zope with apache
by Mosquito 05 May '03

05 May '03

Hey there, I'm using linux 8.0 with KDE Desktop. I've got zope running on a medusa server at the moment, the one it came with. I've also got an apache server running and I was wondering how I can integrate the zope interface to be used with my linux apache server. I'm a total linux nub so go easy on me . ~Mosquito

Zope Server on Linux
by Mosquito 30 Apr '03

30 Apr '03

Hello everyone, I'm new to LINUX, ZOPE, PYTHON, and this mailing list. I have a ZOPE server running on Linux and I'm trying to get my forums to work. They require PHP and mySQL both of which I have but I'm not sure how to install them into my ZOPE server. Any suggestions? ~Mosquito

Zope Win32 service (was RE: [Zope] Binary Compatibility)
by Adam Getchell 09 Apr '03

09 Apr '03

Lukas, It doesn't appear to be the case if you're running Zope under Windows. Uninstalling Zope-2.5.1 doesn't remove the Zope service, and when you install 2.6.0 the Zope service pointing to $INSTANCE_HOME/bin/lib/win32/pythonservice.exe no longer functions. Is there a workaround for this? (ie, a way to uninstall and reinstall the service). I've seen this happen on 3 zope machines, so it's reproducible. Thanks, -----Original Message----- From: Lukas Zapletal [mailto:lzap@root.cz] Sent: Tuesday, October 22, 2002 5:41 AM To: zope(a)zope.org Subject: [Zope] Binary Compatibility Dears When I move out data.fs from v2.5.1, install 2.6.0 and move data.fs back will everything ok?

Virtual Host Monster does not work with the absolute_url()
by Tom Cameron 14 Feb '03

14 Feb '03

I am finding that the Virtual Host Monster does not work with the absolute_url() method of several objects. It seems to work fine for all other things, but when I try to call the URL of an object like this..... <dtml-in "thismodel.getReports()"> <A HREF="<dtml-var "_['sequence-item'].absolute_url()">?assessmentid=<dtml-var thisassessment>" TARGET="_newer"><dtml-var "getTitleOrId()"></A> </dtml-in> It always returns the path back to the real root of Zope. It completely ignores that there is a Virtual Host Monster. I am certain that my Apache rewrites are ok, Ive been using it for many months with no problem. It is just the absolute_url() method that does not work. Any hints? Tom

XMLDocument
by Einar Næss Jensen 04 Feb '03

04 Feb '03

I am using the product XMLKit and its XMLDocument and XMLproxy. (have tried ParsedXML, but it doesn't seem to display my norwegian characters and I don't have time to look into that matter). XMLproxy works just the way i want it. now, inside this xml there is a few lines i want to extract: <CELL ROWSPAN="1" COLSPAN="1"> <emnekode>hfmv302 <A ID="pgfId-999230" /> </emnekode> </CELL> What i want from this is: <a href="some_url#pgfid-999230">hfmv302</a> when i add "emnekode" to the entities to view, nothing happens. However, if <A> contains data i may extract this by calling <dtml-var A> at the opening tag. I am puzzeled. First of all i would very much apreciate if somone could point me to any documentation on XMLKit. second: if somone understand what i want from the above text, maybe could tell me if I am on the right track when trying to extract data from the xml-document. Are there other ways to do this? how? Thanks to everyone who have answered my recent postings. Einar -- Einar Næss Jensen Avdelingsingeniør EDB-HF 735 90750

Missing pyexpat.so in Zope 2.6 binary for linux
by Johan Lübcke 21 Jan '03

21 Jan '03

Hi! When I have a PageTemplate with a non-standard content type (text/vnd.wap.wml) I get an error: -- 8< -- Site Error An error was encountered while publishing this resource. Error Type: ImportError Error Value: cannot import name expat -- 8< -- It works on the Windows version but on linux (Zope-2.6.0-linux2-x86.tgz) I had to copy the file pyexpat.so from another Python2.1 installation. Is there a better way to do it? (Would compile my own solve this?) And where should I report the bug? / Johan Lübcke

RE: Zope and MySQL on Windows
by Deb B. 15 Jan '03

15 Jan '03

I came to this group today to see what I could find on a particular ZOPE/MySQL issue I'm having. It relates to this thread, somewhat. I hope someone can give me some insight. I have ZOPE installed on a WIN98 machine that is acting as a temporary server until we go through a complete network upgrade to Windows 2000 Server, et. al. I have a development workstation that is using Windows 2000 Professional. This machine is where I have installed MySQL. So, I have ZOPE on one machine and MySQL on the other. I installed the myODBC from mysql.com because I couldn't get any of the ZMySQLDA/MySQLdb products to work on any version of Windows (obviously it favors the Unix/Linux environment). Well, Windows is what I'm stuck with now. I created databases, set up my ODBC connections, set up my Z SQL Methods and SQL Forms (depending upon which databases I access) and can access the databases with beautiful results on my ZOPE pages......BUT.....the results are extremellllllllllllllllllllly slow in coming. Even small databases with just a few records take forever to come up even with the most basic of SQL statements using either SQL Forms (for example, my Purchase Order database): <dtml-var standard_html_header> <dtml-if CheckPermissions> <dtml-unless REFERER><dtml-call "REQUEST.set ('REFERER',HTTP_REFERER)"></dtml-unless> <dtml-unless sqf_edit_method><dtml-call "REQUEST.set ('sqf_edit_method','edit')"></dtml-unless> <h3>> <dtml-var title_or_id>: <dtml-var document_title> (List)</h3> <P> <a href="&dtml-URL2;/">Up</a> - <a href="&dtml-REFERER;">Back</a> - <a href="list?REFERER=&dtml-REFERER;">List</a> - <a href="add?REFERER=&dtml-REFERER;">Add</a> <br><br> <table CELLSPACING='&dtml-table_cell_spacing;'> <tr BGCOLOR='&dtml-internal_title_color;'> <th>P.O.#</th> <th>Order Date</th> <th>P.O.

It's daaaaaaaaaaaaaaawwwwwwwwwwwwwwwggggggggggggggg slowwwwwwwwwwwwwwwww though. I even went so far as to perform table structure tests on my MySQL databases to ensure I was optimizing them for the fastest performance. Any searches done through a MySQL client returns quick results but I want all of their access to these databases to be web- based (i.e., through ZOPE site). Help! Thanks.
