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.

How do I write to a text file from Python?
by Jakob Schou Jensen 09 Sep '08

I would like to create a File object in the and store some text in it from a Python script. Everything I try seems to end up in a security restriction of some kind. Is there some obvious way that I have overlooked? Thanks, Jakob Schou Jensen

Styles of import in Zope (2 and 3)
by Marco Bizzarri 31 Aug '08

31 Aug '08

Please, feel free to point me to The Fine Manual to read, if this has been answered and written many times. After reading the article "Importing Python Modules" (http://effbot.org/zone/import-confusion.htm) I had many doubts about the style to use in imports in Zope 2 and Zope 3. The article points to a style which should be: from package.subpackage import module and then use module.MyClass Is this the recomended style in Zope2/3 also? Regards Marco -- Marco Bizzarri http://iliveinpisa.blogspot.com/

Is there any other place where the topic is addressed? Regards Marco -- Marco Bizzarri http://iliveinpisa.blogspot.com/ http://notenotturne.blogspot.com/

Writing a testcase for a Plone 2.5 product - ztc.installPackage isn't available
by Israel Saeta Pérez 28 Aug '08

28 Aug '08

I've posted this message to the plone-users list, but since nobody has answered and I think it's really related to Zope, I'm reposting the message here. My apologies if you receive this message twice. Hello list, I'm trying to write some automated test for an *eggified* content-type product I'm developing for Plone 2.5. My question is: Is possible to install eggified products in zope-2.9.8 using ZopeTestCase? And now the context: Following the PPD book, I've put the following into the tests/base.py file: *** # base.py from zassh.eventoDeportivo.config import PROJECTNAME from Testing import ZopeTestCase from Products.Five import zcml, fiveconfigure from Products.PloneTestCase.layer import onsetup @onsetup def setup_eventoDeportivo(): fiveconfigure.debug_mode = True import zassh.eventoDeportivo zcml.load_config('configure.zcml', zassh.eventoDeportivo) fiveconfigure.debug_mode = False # Let Zope know about the product we require above-and-beyond a basic # Plone install (PloneTestCase takes care of these). ZopeTestCase.installProduct(PROJECTNAME) # PROJECTNAME = "zassh.eventoDeportivo" # Import PloneTestCase - this registers more products with Zope as a side effect from Products.PloneTestCase.PloneTestCase import PloneTestCase from Products.PloneTestCase.PloneTestCase import setupPloneSite # Set up a Plone site setup_eventoDeportivo() setupPloneSite(products=[PROJECTNAME,]) class eventoDeportivoTestCase(PloneTestCase): """Base class for integration tests for the 'eventoDerpotivo' product. This may provide specific set-up and tear-down operations, or provide convenience methods. """ *** But when running the tests from a buildout, ZopeTestCase can't install the zassh.eventoDeportivo product: dukebody@schrodinger trunk $ bin/instance test -s zassh.eventoDeportivo Running tests at level 1 Installing CMFCore ... done (0.013s) [...] Installing kupu ... done (0.031s) Running Products.PloneTestCase.layer.PloneSite tests: Set up Products.PloneTestCase.layer.ZCML in 1.958 seconds. Installing zassh.eventoDeportivo ... NOT FOUND and obviously all my tests fail. PPD uses ztc.installPackage instead of ztc.installProduct, but the installPackage method isn't availabe in Zope-2.9.8-final, which I'm using with Plone-2.5.3. [1] My question was: Is possible to install eggified products in zope-2.9.8 using ZopeTestCase? If so, what's wrong in my base.py file? Thanks in advance.

iterating over result sets in python
by Garry Saddington 24 Aug '08

24 Aug '08

I am trying to iterate over a result set from a zsql method in a python script in Zope 2. In the results is a date field. What I want to do is test whether a date is younger than the date in the previous row by at least 30 days but I am having problems working out how, not coming from a pythonic background. Could anyone point me in the correct direction? Regards garry
