Undo error

I always have a trouble to undo something. Zope: 2.5, not updated OS: Linux SuSE 8.0 Pro Session is on ZODB, not in temp folder. Anybody know what this error means and how to avoid this? Error Type: UndoError Error Value: Couldn't undo change to '\x00\x00\x00\x00\x00\x00\x1c4' because non-undoable transaction Traceback (innermost last): File /opt/zope/lib/python/ZPublisher/Publish.py, line 150, in publish_module File /opt/zope/lib/python/ZPublisher/Publish.py, line 114, in publish File /opt/zope/lib/python/Zope/__init__.py, line 159, in zpublisher_exception_hook (Object: newTask) File /opt/zope/lib/python/ZPublisher/Publish.py, line 102, in publish File /opt/zope/lib/python/Zope/__init__.py, line 173, in commit File /opt/zope/lib/python/ZODB/Transaction.py, line 234, in commit File /opt/zope/lib/python/ZODB/DB.py, line 590, in commit File /opt/zope/lib/python/ZODB/FileStorage.py, line 1134, in transactionalUndo (Object: /opt/zope/var/Data.fs) File /opt/zope/lib/python/ZODB/FileStorage.py, line 1169, in _txn_undo (Object: /opt/zope/var/Data.fs) File /opt/zope/lib/python/ZODB/FileStorage.py, line 1260, in _txn_undo_write (Object: /opt/zope/var/Data.fs) UndoError: (see above) -- Regards, Bogdan We've found by experience that people who are careless and sloppy writers are usually also careless and sloppy thinkers (often enough to bet on, anyway). -- ESR (http://www.tuxedo.org/~esr/faqs/smart-questions.html)

Thanks Dieter, I knew it was simple.... -----Original Message----- From: Dieter Maurer [mailto:dieter@handshake.de] Sent: Saturday, November 02, 2002 6:03 PM To: McDonnell, Larry Cc: 'Zope@Zope.

You split it at "/" and rearrange the peaces: In Python (Script): month,day,year= datestring.split('/') return '20%02d/%02d/%02d' % (year,month,day) Dieter

Can I have my old tracebacks please? (2.6.0 not same as 2.5.1)
by Tony McDonald 04 Nov '02

04 Nov '02

Hi all, I've just spent the best part of Sunday going through the 2.6.0 distribution (mostly in doc/ and lib/OFS/SimpleItem.py, with lots of grepping for all sorts of strings), google, and the mailing list archives trying to figure this out. No joy. Here's a 2.5.1 traceback for a NotFound error  The unfound object is in the folder called 'resources'. If there's an error in a script, that is outlined too. And here's the same one for 2.6.0 (this time a KeyError Error)  It seems the 'Object' line is missing. I've edited my standard_error_message so I have ; ... <dtml-var standard_html_footer>  Can anyone give me an idea of how to get 2.5.1 functionality back (just Object would be enough I think). By the way, the HTTP_TRACEBACK_STYLE environment variable which controls the appearance of error tracebacks when not in debug mode, which was introduced in 2.5.1 is nowhere to be found... I really like the new features in 2.6.0, so I'm assuming that there's a hidden environment variable (or something - I couldn't find anything in z2.py that implied it's a flag). If someone can point me in the right direction...

Object type association in ftp
by Andreas Brinner 04 Nov '02

04 Nov '02

Hej, I'm actually developing a product for zope and I now have exactly the problem described in http://www.zope.org//Wikis/DevSite/Proposals/ObjectTypeAssociationAndDeathT oIndexHtml - changing the standard association between file extensions and object types for ftp access. As I can see on the page http://www.zope.org/Wikis/DevSite/Projects/Zope2.6/ProposedFeatures (the proposed features for zope 2.6) this should be solved for Zope 2.6. My question now: Is it really solved and is there any example or howto, where I can see how to implement it? Thanks, Andreas

Re: [Zope] content-type weirdness (was: Redirect weirdness)
by Ken 03 Nov '02

03 Nov '02

Hi again, On Sat, 2 Nov 2002, I wrote: >Can I set a content-type header along with the redirect? >I've searched... >I wanted this to be automatic, and the only hint about the content-type would be from the string '.pdf' in the URL... > And where did 'contype' come from?? >>this is a good question Thanks! I'm still hoping for some enlightenment.. Again: External links on my page go to a script which builds the URL and does a RESPONSE.redirect. When the object of the redirect is a PDF, the script does not complete. It looks as if I need to set a content-type header at the same time, but how? And, out of curiosity, how does 'contype' get written to Z2.log as useragent for the failed calls? Thanks, Ken

Can I capture results from insert in Z SQL methods?
by Skip Montanaro 03 Nov '02

03 Nov '02

In a Z SQL method I want to create a row in a table which has several foreign keys. The method is going to create other rows in subsidiary tables with some of its inputs, then use their primary keys as foreign keys in the final insert. For example, a contact table has foreign keys referring to address and phone tables. The code looks something like begin; # voice phone insert into phone ( ... ); # fax insert into phone ( ... ); insert into address ( ... ); insert into contact ( name, email, address_id, phone, fax ) values ( ... ); commit; In the final insert I need row ids corresponding to rows I inserted in the phone and address tables. Can I capture them as a result returned from the earlier inserts or do I need to do a subselect in the last insert, like so: insert into contact ( name, email, address_id, phone, fax ) values ( <dtml-sqlvar name type="string">, <dtml-sqlvar email type="string">, (select max(id) from address where address1 = <dtml-sqlvar address1 type="string"> and address2 = <dtml-sqlvar address2 type="string"> and city = <dtml-sqlvar city type="string"> and state = <dtml-sqlvar state type="string"> and postal_code = <dtml-sqlvar postal_code type="string">), (select max(id) from phone where phone_area = <dtml-sqlvar phone_area type="string"> and phone_number = <dtml-sqlvar phone_number type="string"> and type = 'work'), (select max(id) from phone where fax_area = <dtml-sqlvar fax_area type="string"> and fax_number = <dtml-sqlvar fax_number type="string"> and type = 'fax') ); or do Z SQL methods support some other mechanism? I didn't see any examples of such stuff in the Zope Book. (I'm using the Psycopg DA, Zope 2.5.1.) Thanks, -- Skip Montanaro - skip(a)pobox.com http://www.mojam.com/ http://www.musi-cal.com/
