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

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

grufspaces, scripts and inherited permissions
by sguglia＠arrows.it 29 Feb '08

29 Feb '08

Hello everybody, I created a group member and a group folder (using grufspaces), from where I run a python script. The result of this script is a n number of brain objects (indexed_file) indexed in portal_catalog. All object are correctly indexed, so I can search contents, but as a groupmember only. the question is: how can I modify (from the script) permissions of the brains objects in order to get them searchable from anybody? the main part of my script: for pub in context.query_05(idx_value=idx_value): object = '/query_06/' + pub.id + '/indexed_file' my_catalog.catalog_object(pub, object) thanks!

HI all, I think about altering of ZCacheable_manage to show all cached variants of cache keys ( Names from the DTML namespace) with their times and invalidation of selected single variant. Do somebody have this kind of thing realised? Many thanks, J. Lukesh

Acquisition / proxying object
by Joerg Baach 27 Feb '08

27 Feb '08

Hi *, I am trying to have a folderish object that acquires from a user object (ldapuserfolder). It should have its own properties and contents, but fall back to the ones of the ldap user. I have created an object, extending Folder, and it behaves nicely in zopectl debug. When I try to access it through e.g. a python script I get an: Error Type: Unauthorized Error Value: Unable to find __roles__ in the container and the container is not wrapped. Access to 'dn' of test, acquired through (LDAPProxy at /testfolder/ldapproxy), denied. I am sure its my lack of understanding of acquisition. I am trying to bascially put ldap user object 'on top' of the aquisition line (with the ldapproxy at the bottom), but obviously failing in doing so. Any ideas?

Zope 2.11.x and 2.10.x
by baiewola 27 Feb '08

27 Feb '08

I want to install Zope 2.10.5 or 2.11.0-al on Mac OSX 10.5.2, which comes pre-installed with Python 2.5.1. Install docs for both say they don't work with 2.5. Does that mean they don't work with anything 2.5 and above, or only version 2.5 specifically? Has anyone been able to install either of these Zopes with Python 2.5.1?

Static adquirable resource
by Garito 27 Feb '08

27 Feb '08

Hi! Some weeks ago Tres point us how to declare static resources with five You could create a configure.zcml file for your product and put some code like these: <configure xmlns:browser="http://namespaces.zope.org/browser"> <browser:page for="*" name="ZSmanage" template="recursos/ZSmanage.pt" permission="zope2.Public" /> </configure> and magically you could use it as: http://server:port/ZSmanage But if you try to use ZSmanage as an acquired object you could Can I do something at this respect? I would like to use ZSmanage in a different context, can I? Thanks! -- Mis Cosas http://blogs.sistes.net/Garito Zope Smart Manager http://blogs.sistes.net/Garito/670
