Why do you want to recode into DTML? I think that is piece of good code and much faster than DTML. You could try following replacing (original line of your code, follows with DTML code), but not tested: > rec = context.test_select_sql() <dtml-call "REQUEST.set(rec , test_select_sql())"> > print "Fields definitions" Fields definitions > recordset = rec.dictionaries() <dtml-let "recordset = rec.dictionaries()" > rownum = 1 <dtml-call "REQUEST.set(rownum,1)" > for record in recordset: <dtml-in recordset> > print "Row %d" % (rownum), "check", record Row <dtml-var rownum>, check <drml-var sequence-item><br> > rownum = rownum + 1 <dtml-call "REQUEST.set(rownum,rownum+1)" </dtml-in> and so on on the rest of code. > for key in record.keys(): > print key, "=", record[key] > print "-" * 80 > return printed

read-only-database
by Ulla Theiss 17 Mar '09

17 Mar '09

Hello list, I want to run the database in read-only mode from CD and configured it accordingly in the zope.conf: read-only-database on enable-product-installation off zserver-read-only-mode on Starting Zope, I get the following error: Traceback (most recent call last): File "\Programme\Zope\lib\python\Zope2\Startup\run.py", line 56, in ? run() File "\Programme\Zope\lib\python\Zope2\Startup\run.py", line 21, in run starter.prepare() File "E:\Programme\Zope\lib\python\Zope2\Startup\__init__.py", line 98, in pre pare self.startZope() File "E:\Programme\Zope\lib\python\Zope2\Startup\__init__.py", line 257, in st artZope Zope2.startup() File "E:\Programme\Zope\lib\python\Zope2\Startup\__init__.py", line 47, in sta rtup starter.setConfiguration(cfg) File "D:\Programme\Zope\lib\python\Zope2\App\startup.py", line 56, in startup File "D:\Programme\Zope\lib\python\DBTab\DBTab.py", line 96, in getDatabase File "D:\Programme\Zope\lib\python\DBTab\DBTab.py", line 113, in _createDataba se File "E:\Programme\Zope\lib\python\Zope2\Startup\datatypes.py", line 163, in o pen DB = self.createDB() File "E:\Programme\Zope\lib\python\Zope2\Startup\datatypes.py", line 160, in c reateDB return ZODBDatabase.open(self) File "D:\Programme\Zope\lib\python\ZODB\config.py", line 97, in open File "D:\Programme\Zope\lib\python\ZODB\config.py", line 133, in open File "D:\Programme\Zope\lib\python\ZODB\FileStorage\FileStorage.py", line 112, in __init__ File "D:\Programme\Zope\lib\python\ZODB\lock_file.py", line 57, in __init__ IOError: [Errno 13] Permission denied: '\\Zope-Instance/var/Data.fs.lock' r+ means opening the file for updating. This has not to do anything with read-only. Does anybody know what I have to configure additionaly, that read-only works? I run Zope 2.8.4 on windows. Many thanks in advance, Ulla.

Yup, that and Squid 3's "not production quality" status makes the whole Squid/ESI thing a total non-starter, which is a shame... ...but I do wish, as a result, that people would stop touting it as a way to scale Zope apps. cheers, Chris -- Simplistix - Content Management, Zope & Python Consulting - http://www.simplistix.co.uk

Zope + Oracle + Cron
by David VanKirk 05 Feb '07

05 Feb '07

We have zope installation that uses an Oracle backend to store data on. We also have the system setup to do a backup of the database and Zope Installation everyday. Everything runs smoothly until it comes time to start Zope back up. For some reason whenever the script tries to start Zope back up, it comes up but with a broken ZOracleDA product. It complains about not being able to find the library file called libclntsh.so.9.0. If I try to start Zope myself from command line right after the script is done running (actually stop it then start it again) it works and connects to Oracle fine. I've tried using "nice" to up the priority level but it doesn't seem to work. I also thought that maybe I wasn't giving oracle enough time to start up so I've tried adding sleep commands to the script, again, with no luck. If anyone has any experience in this field or has any suggestions, please let me know. This is a quite annoying situation, as this server is quite important to the company and downtime is a bad thing. -David

I don't understand why the uid of 1049298593 works in retrieving the record from the zcatalog, but not when used to delete the record from the zcatalog?! (I have looked at the code in Catalog.py and nothing in the uncatalog_object method provides any hints as to why this problem is occuring). Any ideas would be really appreciated! Thanks, Jonathan

Production Advice
by Jonathan Cyr 11 Oct '06

11 Oct '06

Greetings All, After a long dev cycle, I'm putting a Zope web app into production shortly... and need some advice. What is a good daily backup strategy with Zope 2.71? I'll be running ZEO, and only use three add-on products, Formulator, VarImage and PIL. My application consists of regular items in the ZODB, two python Products, and a half-dozen ZClasses Right now, I'm developing on a WinXP machine, and am considering SuSE 9.1 for my spec, any experiences, good or bad?... YAST2-installed or manually? All advice would be helpful as I weigh my options, -Jon Cyr cyrj(a)cyr.info

doc string rules
by Dennis Allison 10 Oct '06

10 Oct '06

I just had LocalFS break under Zope 2.6.4 with Python 2.3.4 due to a "missing docstring". What are the current rules? Must everything (procedures, methods, classes, modules) have docstrings? Even when running with Z_DEBUG_MODE set to "yes".
