DCO2: workaround for non-select errors
by Kyler B. Laird 07 Jun '01

07 Jun '01

I have been unable to fully use DCO2 since switching to Linux (and Oracle 8 client) for my Zope server. Although I can "select" without a problem, I received errors when executing "queries" that didn't return data. (drop/create/insert) Today I noticed the DCO2 beta, so I tried it. Instead of the strange and varied errors I was getting before, I always got an exception from fetchone(). That was just too tempting. So...I wrapped the fetch in fetchone(). if self._result is None: try: self._result = self._cursor.fetch(self.arraysize) self._rcount = 0 except: return None Ta da! Another Quickie Kyler Kludge! Sure, it's probably a terrible way to do it, but it seems to work great. I love Open Source. --kyler

I hoped there was a mechanism like there's in zclasses, where I only have to change the zclass to get the new properties. Is my problem really one of the prices which have to be paid in order to get the benefits of python products over zclasses? cheers, oliver

Debugging, the Zope > Oracle connection, ZOracleDA and truncation?
by Chris Beaumont 06 Jun '01

06 Jun '01

Does anyone have any idea why some query strings (inserts) using ZOracleDA connecting to an Oracle 7.3 database, might be truncated at between 2000 and 4000 characters? This is not the LOB problem, (they are not single varchar or long fields) I am talking about the length of the query itself, including the values.. (I have already implemented a workaround for the 2000 char limit per field), its something else and whatever it is, its very difficult to debug... What are the best ways to debug the Zope > oracle connection? Trying to figure out what is happening is like trying to navigate in the dark, given Oracle's terse error output..

python products and properties
by Oliver Bleutgen 06 Jun '01

06 Jun '01

Hi, is there a way to handle properties in python products in order to get similar funtionality in as propertysheets in python? I'm developing a product right now and it may be that I have to add some properties later (while in production). Right now I have to manually assign a newly added property to already existing instances, because adding the property in the _properties class attribute breaks the properties management tab of these instances. Am I missing something? What do others do? Oh yeah, and I even have a great proof that I tried to find an answer in the archieves, check out this nice page: http://www.y-tex.com/PYthon.html It totally sold me on python products, I really didn't know that they are *that* potent. cheers, oliver

Yep, the docs still need some work, but part of the difficultie lies in finding the right doc. That's why we have the mailing list collective :) Also, on the subject of live editing, did versions croak? I thought you could use them to avoid editing a live site. Maybe he means using versions inside Squishdot or zwiki -- anybody know if this works? By saying the site isn't CVS'd, he means that he doesn't have a history of changes to the site. Obviously he hasn't seen the history tab -- it rocks!

Zope isn't well documented. The thing about live editing (but using CMF you have some moderators accepting the content - but maybe this isn't what he means?) What does he mean by "The site isn't in CVS"? Zope is "CVS'ed". There are some CVS products for Zope. Maybe someone should try to send him an email ?

So, thankfully, not a Zope issue. I have one last thing to offer. With ODBC, there are "user" DSN and "system" DSN. You want to be using a "system" DSN, but usually it's "user" connections that get set up. If your Access DSN is not a "system" type, create one and test that. Set it up when you are logged in as Administrator. I bet it will work. Let us know how it works out, please.
