Catching SQL Exceptions in an external method
by Stolker, Wim 23 May '00

23 May '00

Hi, I have a burning question ... Does anyone know how to catch exceptions from SQL methods ( via ZodbcDA ) in an external method? I do not know how the exceptions are named. If I catch the exception with a general 'except:' statement it works but I cannot see the info from the exception, so I want to write something like except sqlerror_or_something, e: do_something_with_e I have not been able to find out what I should write instead of sqlerror_or_something Some context: I have an external method that I call via xmlrpc. This method calls a ZSQL method, does some postprocessing and returns the result to the ( java or python ) client. Everything works fine EXCEPT when there is an error. This error shows up in the client as 'internal server error' without further information. If I call the external method from a browser I can see the specific SQL error. So I tried to catch the specific error in the external method in order to marshall the info and send it back to the client. Any help greatly appreciated. Have a nice day, Wim

Yeah - I thought the problems had been sorted under Win98 - but I re-discovered this gotcha (which I was getting under NT4): you can copy .htm files TO Zope but not back again. And changing the file name and/or extension doesn't offer a workaround. Bit of a shame that ....

does this app exist?
by paul beard 23 May '00

We're considering using zope to handle some internal groupware-type functions, with WorldPilot as the base. What we need is the true Outlook killer: scheduling. Any word on this as a feature to WorldPilot or hints on how hard this would be implement? By scheduling, I mean the notion of creating an event, inviting others to it via email or WorldPilot, and booking resources like meeting rooms against it. -- Paul Beard / 206 728 4282 x138 Fizzylab / 2025 First Ave, Suite 1150 Seattle WA 98121

Updating one data.fs from another
by Graham Chiu 23 May '00

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I do development on my site on my notebook, and then rather than overwriting my production data.fs, I then manually make the changes to the production data.fs by create/cut/paste from my development data.fs which is all very painful.

My browser also doesn't support cut/paste of whole documents from one data.fs to another, just the data whereas it supports this within a data.fs.

SQLSession Problem
by wai＠mahirnet.com 23 May '00

23 May '00

Hi All, I'm using zope 2.1.6 with apache server on NT platform. and I had a problem with SQLSession. I tried to put in the '_force_new_session' flag whenever I called a session, so I can have a fresh SessionID. But I always got a error return with a message "TypeError". So I wonder if this is the correct way to call the session component : <dtml-call "Session('_force_new_session=1')"> Please help. Cheers Wai

Actually, it *is* possible still to add the test_project objects; the problem is that the management interface is confused about the list of possible options. To prove this to yourself, follow Eric's recipe above, and then invoke the add form directly through the URL, e.g.: <URL http://my.site/a_test_folder/a_test_project/manage_addProduct/test_product/…> If you fill out the ID and press 'Add', le voilà! The management interface is using some unhappy heuristics in its attempt to determine the legal set of addable classes: * In the initial case, the only possible item is test_project, so it hard-wires the "Add" button to it (and doesn't show a list!) * In the second case, the "nested class rule" kicks in before the MI gets up to the top of the product, and so the nested "project team" class is the only one found; again, the MI wires up the "Add" button directly, with no list. * If you had more nested classes, you would see a list of them (but still not the project class itself). Likewise, if you add other meta-types to the "Subobject" tab of the class, they will appear in the list as well. This problem is a ZClass bug and should be reported to the Collector: http://classic.zope.org:8080/Collector (Actually it looks like a duplicate of #811).

Deleting folder-like objects.
by John Morton 23 May '00

23 May '00

After a few experiments, I've observed a couple of things about deleting folder-like objects: 1) You can delete them with the same practiced easy as any other object, along with everything in it. No 'Are you sure you want to shoot yourself in the foot' dialogs, or anything. (How hard to implement with manage_beforeDelete?) 2) Deleting a folder effectively removes everything under it (well, you can't navigate to them, AFAIK), but it doesn't invoke the manage_beforeDelete methods of it's decendants. Any reason for this, or should I proceed straight to the bug collector? John.
