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

How to use Zope2 products in Zope3 ?
by Jason Cunliffe 16 Nov '07

16 Nov '07

Hello I have some Zope2 products I want to use in Zope3. First up these: -- LocalFS -- ZopeShortcut -- SWFFile Confused by changes... I can't find any 'Products' or 'Import' folders in my Zope3 instance... Does this mean all those good products have to be rewritten using some new super-complexificated Zope3 syntax? I hope not. What am I missing please..? Thanks for any advice Jason

folder like shortcut / symlink / pointer / urlredirect
by Ben Bartrum 31 Oct '07

31 Oct '07

Hello The DTML code below populates a large menu with folders and their descriptions, however one of the items in the menu should now point to a URL on a different server. I can change the code - for example make it ordinary HTML, or add the new URL above or below, but I want to know if it is possible to make a folder-like object that points to the new URL, and will work with no change to the code below: Choose an option: </p> <dtml-in "services.objectValues('Folder')" skip_unauthorized="1" sort="menuorder"> <dtml-if "_.int(showhide)==1"> <div class="bulletList"> <strong><a href="<dtml-var absolute_url>/index.html"><dtml-var title></a></strong> <dtml-if "description!=None and description!=''"> <br /> <dtml-var description> </dtml-if> </div> </dtml-if> </dtml-in> Thanks

I tried all the item specified in th "Document Library". But that install procedure checks-out complete Zope3 package and tries to compile and run it. I dont see any documentation related to this in their site. I agree that my request here is more related to "Document LIbrary" and just wondering if someone in this group tried it.

Document Library & Zope
by junk 31 Oct '07

31 Oct '07

Dear Group, I am new to Zope and I am helping few students on their academic project. The project is to create a simple Document Management System workflow. we are evaluating various option and I came across the module INFRAE's "Document Library'. BUt I cannot install it in my Zope3 or Zope 2.10.4. As per the Document Library's install.txt it is trying to install a new Zope. Is there any way I could install in my existing Zope. Appreciate any pointers in this regard. Best regards Dominic PS: I would like to know how to integrate with Silva (Hope this is not related to this group)

Slicing a lazy sequence
by Miles 30 Oct '07

30 Oct '07

Hi, I'm looking at a performance issue with a site. Part of the problem seems to be the time taken to load all the attributes to construct a large number of brain objects. I think I remember reading somewhere once that if you slice a sequence of catalog results as follows: rs = portal_catalog.searchResults(portal_type='my_type') return rs[10:30] or even <dtml-in "portal_catalog.searchResults(portal_type='my_type')" start=10 size=20> that this "undoes" the advantage of the lazy sequence, as it has to iterate over all the items in the sequence to produce the slice. Is this correct or have I just imagined it - can anyone confirm?! And if I haven't imagined it, how can I do this more efficiently? Thanks, Miles
