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

listing files in a LocalFS folder
by Alan 05 Nov '06

05 Nov '06

Hi List! I am doing that: <ul> <li tal:repeat="item context/objectValues"> <a href="ABSOLUTE_URL" tal:attributes="href item/absolute_url" tal:content="item/title_or_id">SUB-OBJECT TITLE OR ID</a></li> </ul> And it works to list the content of my main folder. Within my main folder, there's a LocalFS folder (let's call LFSfolder). When using the code above and I can even click in LFSfolder and access its content. However, what I want is: <li tal:repeat="item context/LFSfolder/objectValues"> ^^^^^^^^^^ and link the content inside LFSfolder. But it does not work. Does anyone know a way of doing what I want? Many thinks in advance.

invalid load key
by William Heymann 31 Oct '06

31 Oct '06

This is the traceback I am getting when I try to pack the db Traceback (innermost last): Module ZPublisher.Publish, line 115, in publish Module ZPublisher.mapply, line 88, in mapply Module ZPublisher.Publish, line 41, in call_object Module App.ApplicationManager, line 426, in manage_pack Module ZODB.DB, line 605, in pack Module ZODB.FileStorage.FileStorage, line 1348, in pack Module ZODB.FileStorage.fspack, line 482, in pack Module ZODB.FileStorage.fspack, line 228, in findReachable Module ZODB.FileStorage.fspack, line 304, in findReachableAtPacktime Module ZODB.FileStorage.fspack, line 377, in findrefs Module ZODB.serialize, line 625, in referencesf UnpicklingError: invalid load key, '^\' How can I find out what object is damaged so I can fix it/remove it? My best guess on what caused the problem was undoing a large set of deletes because someone deleted something they should not have and then deleting those objects again. I tried to run fsrecover.py on the db and it seems to just spin at around 99%. I will run it again and just leave it running and see if it ever finishes but I let it run for a pretty long time already. Also any idea on what could have really caused the problem? memtest did not report any errors when I last ran it and the hard drive diagnostics don't report any issues either. The Zope version is 2.9.5 and the db is about 2GB in size and the point at which fsrecover.py stalls is about the last 4 megs. Thanks
