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

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

How to do...
by Garito 31 Dec '06

31 Dec '06

Hi all! How can I control the way an attribute of a product is readed? __getattr__? __getattribute__? I try the __getattribute__ way but it modifies the property pages Example: I create an object instance of the product and like: Property1 = 'Some text' Property2 = 2006-10-18 I would like to call Property2 like object.Property2 and retrieve the data with the current locale For spanish locale I would like to retrieve 18-10-2006 But if I read the property pages of this object I would like to conserve the given data Is this possible? Thanks! -- Mis Cosas http://blogs.sistes.net/Garito

Zope newbie.... unicode problem
by Tyler Nally 30 Nov '06

30 Nov '06

Greetings all, I'm 100% new to Zope. A complete Zope newbie. I've done web Work for more than a dozen years... just never with Zope. When serving a web page, we get an error that involves the fetching and display of a document to the browser. Evidently, it's choking on some unicode bytes when it's expecting plain ascii. I'm assuming it's /usr/lib/zope2.7/lib/python/Products/PageTemplates/PageTemplate.py that's causing the problem as the data isn't somehow massaged correctly before processing arrives at /usr/lib/python2.3/StringIO.py line 203. I don't know if the bad byte is in a zope template, document, or a database record that it's fetching. I do believe this installation of Zope uses Plone... but I've no idea whether Plone is somewhere used in the error stream of all the different calls. Do I need to post more information? Tell me .. and I'll get it. If this comes down to a patch, I've no idea how-to apply a patch once I get my grubby mits upon the patch. So, I'll need a bit of help with that as well. If I've posted this in the wrong place.. please forgive me and point me to the right place that I might ask the proper folk to help me. Thanks a lot .. and thanks in advance Tyler ====================TRACEBACK=============================== 2006-11-29T11:03:37 ERROR(200) SiteError http://www.teamhancock.com/help/bb-install Traceback (most recent call last): File "/usr/lib/zope2.7/lib/python/ZPublisher/Publish.py", line 101, in publish request, bind=1) File "/usr/lib/zope2.7/lib/python/ZPublisher/mapply.py", line 88, in mapply if debug is not None: return debug(object,args,context) File "/usr/lib/zope2.7/lib/python/ZPublisher/Publish.py", line 39, in call_object result=apply(object,args) # Type s<cr> to step into published object.

acl_users: can not access source_groups

when I click on source_groups in acl_users of a plone site I get athe following trace back. when I comment out the offending assert everything seems to work fine. the check the comment to the assert says: # should be one and only one mapping to 'k' i therefore assume, that some of the userrs or groups are defined at more than one place. how is this possible?
