Re: [Zope] convert python to dtml

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

Wrong time displayed on events
by Kirk Strauser 09 Feb '07

09 Feb '07

I've just installed Plone 2.5.1 on Zope 2.9.6 running on FreeBSD 6-STABLE. On my newly created Plone site, whenever I add an event, it's displayed with the wrong time. For instanced, if I create one that runs between 2006-12-05 19:30 and 22:00, it gets rendered like: (<span class="location">Some Event</span>, from <abbr class="dtstart" title="2006-12-05 19:30:00">2006-12-05 13:30</abbr> to <abbr class="dtend" title="2006-12-05 22:00:00">2006-12-05 16:00</abbr>) The server and I live in the CST time zone, which accounts for the 6-hour offset (as though I entered the time in UTC and it's converting it to CST for display). But since I never entered a timezone anywhere, why's it doing any conversion at all instead of just assuming that all times entered are local to the server? Is there a way to fix this, other than deliberately entering all times for events six hours too late, and letting Plone "fix" the display? -- Kirk Strauser Daycos

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

Zope 2.9.5 -> 2.9.6 DateTime Change
by Brian Brinegar 01 Feb '07

01 Feb '07

Today I started testing Zope 2.9.6. After the upgrade I noticed that some calendar data generated from Oracle was wrong. After some investigation I found that Zope 2.9.6 seems to assign a timezone of GMT+0 when none is specified rather than using the server's timezone. For example, the following SQL query to an oracle database: select TO_DATE('12-13-2006 01:00','MM-DD-YYYY HH:MI') from dual Under 2.9.5 returns: 2006/12/13 01:00:00 US/Eastern Under 2.9.6 returns: 2006/12/13 01:00:00 GMT+0 There was clearly no time zone defined in the query, and it's the same Oracle server. Is this an intended change? We have hundreds of developers working independently within our system so it's not possible to adapt each application to account for this change. Any advice on moving to Zope 2.9.6? In the mean time I my try to back port specific bug fixes into 2.9.5. Thank you, -- Brian Brinegar Web Systems Developer Engineering Computer Network

zope document management
by pol 07 Jan '07

07 Jan '07

Hi all, I would like to share my user view about zope, I would like zope to strive to embody into Data.fs the best trimmed down objects as possible, leaving on the file system most of the content. Text files and pictures should be accessible by external editors, mail should be accessible by external mail readers, and so on. Zope main role would then be to establish connections between external objects, collecting, indexing, sorting and viewing external objects (editing capability would not be needed). Is anybody working in that direction? thank you -- Pol

Wrapping zope with socksify
by Patrick Gerken 07 Jan '07

07 Jan '07

Hello, we wanted to open connections from within zope to other elements. As the other elements require that we connect to them via a socks server, we considered it a good idea to wrap zope with socksify. socksify is a program from the dante package which allows you to add socks support for any network application by just wrapping the application with socksify. It is just like using strace on linux. Now we got the problem that zope randomly crashed. We suspected that the socksify version we used was faulty and tried it with the latest socksify version as a static compiled binary, but had similar problems. Did somebody else try to wrap zope with socksify and had success with it? I found only this hint that application developers should take care of: *select(2)/poll(2)*applications combining non-blocking sockets with select(2)/poll(2) need to make sure they can handle the select(2)/poll(2) call being interrupted. This is due to how the Dante clientlibrary implements support for non-blocking connect(2).But our application crashed randomly, and not when we tried to access certain ftp servers. Best regards, Patrick Gerken

Make folder's default view the contents of an item based on latest date
by Praful Kapadia 05 Jan '07

05 Jan '07

Hi I'm using Plone 2.5.1 on Mac OSX 10.4 and Win XP. I have the following folder structure: Daily News All Archive 2006 Jan Feb ... Jan, Feb, etc are smart folder that select items based on their effective date. This allows news items to be automatically classified. I'd like users to add items to folder All. When users click Daily News, I'd like the most recent item to be shown. I don't want a link to the most recent item but its contents so Daily News always shows the contents of the most recent news item. Someone suggested adding a smart folder (say, Latest) under Daily News and letting it pick items. Then make Latest the default content item for Daily News. This however results in the items being shown as a list of links in Daily News. I want the content of the latest always visible under Daily News. Any suggests? If I have to code something, please provide clues. I've developed in many languages but not Python (I'm going through Python in a Nutshell, at the moment). Thanks Praful
