DCOracle from outside Zope [Q]
by Bruno Mattarollo 17 Nov '99

17 Nov '99

Hello. Excuse me if it's off-topic, but is there some documentation on the methods and how to use the DCOracle module from outside Zope? I mean, I am developing a Zope site and I need to access my Oracle server from python scripts. I cannot use them from within Zope, don't ask why ;-) And BTW, is there some documentation or someone can give me a hand on how to use a ZSQL method and how the data is passed to an External method?

Not Neccisarily Zope Weekly News, please read.

Hi. Not an hour ago I sent out an email titled "FYI: Zope Weekly News". The paragraph at the beginning should give a striking clue that it wasn't _THE_ Zope Weekly News, but merely a candidate for the position. If you are archiving or redistributing the Zope Weekly News, PLEASE, disregard my mailing from earlier today. The real Zope Weekly News will appear, as always, Wednesday evening. Thanks for your patience, Mike Pelletier

Hi, Zope 2.1 beta one was released this week. There will probably be a relatively short beta period before Zope 2.1 final comes out. Zope 2.1 focuses on boosting reliability and performance. In other news, Zope community members continue to crank out code, documentation, publicity, and all manner of excitement. * Zope 2.1.0 beta 1 was released.

Startup problems - Help
by RICHARD PAUL COOPER 17 Nov '99

17 Nov '99

First off the first problem that I had was that when I tried to start the zope server nothing at all would happen, after looking at the /etc/rc.d/init.d/zope file I found that it was using the deamon command to load the server, I don't have such a command installed for some reason (Mandrake-Linux 6) so I removed the daemon command and simply started the server plainly. Does this make any sense at all? Now when trying to start the zope server I get the following error: File "z2.py", line 376, in ? exec "import "+MODULE in {} File "<string>", line 1, in ? File "/usr/share/zope/lib/python/Zope/__init__.py", line 95, in ? import Globals, OFS.Application, sys File "/usr/share/zope/lib/python/Globals.py", line 91, in ? import TreeDisplay, string File "/usr/share/zope/lib/python/TreeDisplay/__init__.py", line 86, in ? import TreeTag File "/usr/share/zope/lib/python/TreeDisplay/TreeTag.py", line 95, in ? from zlib import compress, decompress ImportError: No module named zlib This seems to tell me that I have the Python module zlib missing, however I have Python-1.5.2-2 installed so everything should work, right? I would appreciate any help. Thanks in advance. Paul Cooper - rpc7(a)aber.ac.uk "I can't think of a clever, intelligent or humorous sig - guess that means I'll just have to steal one."

Refreshing a Window
by Joshi, Sunit 16 Nov '99

16 Nov '99

Hello All I'm generating chart gifs which are loaded when the user clicks on a button, however it seems that sometimes I have to click on the Refresh button to get the new chart to be displayed. Otherwise it shows the old one (in cache). Is there a way to call the refresh action after I click the button to generate GIFs and show the DTML showCharts which has the line <img src="http://RPA/Html/Graph1.gif" alt="LoginTime"> in the dtmlShowCharts to load the new file. I'm sure this is not the right way to do it, but if I make an image Object how do I reload it each time I make a new chart. thanks Sunit INTERGRAPH SOFTWARE SOLUTIONS Sunit Joshi Support Engineer Process and Building Solutions ____________________________________ ___ Huntsville, Alabama 35894-0001 Tel: (256)730-3059 Fax: (256)730-3028 mailto:sjoshi@ingr.com

Default DTML in ZClasses
by Alexander Staubo 16 Nov '99

16 Nov '99

I have a folderish ZClass containing objects, such as DTML Methods. As it turns out, while those objects are attached to the class definition, not the class instances, there is no way to _override_ those objects by placing, say, a DTML Method in the instance with the same name as that inside the class. (Instead, you must derive a new ZClass from the first, and override them there.) It seems that convention is to have the ZClass/product create "default objects" upon construction. Confera, Squishdot, etc. all do this. I wonder if there should be a standard way of doing creating such default objects. I currently put objects in my ZClasses and name them things like "TemplateFoo". Then the constructor for that class does something like: <dtml-let Obj="TodoFolder.createInObjectManager(REQUEST['id'], REQUEST)"> <dtml-call "manage_addProduct['OFSP'].addDTMLMethod(Item, 'Foo', file = Obj.TemplateFoo)"> </dtml-let> ...which copies TemplateFoo from the class into the newly created instance. Of course, while this works, it feels kludgy.

Re: [Zope] ODBC - 1 step forward - woops I tripped

>Could there be a file permissions issue? I'm not up on NT file permissions, but >maybe the text file just has the wrong permissons. Anyway, I'd just go directly >to one of your DB2 databases. I often have trouble getting those Jet drivers >working right on the fly, but I never had a problem with SQLAnywhere. That is why I stated that I was logged on as a local Admin. I've essentially got 'root' access. (Ya know, same thing ... only different ;-) I'm already trying to go directly to DB2 through ODBC since it looked like I was getting stuck somewhere in the ODBC Text Drivers. I ran a trace and was seeing stupid errors about unsupported this and that and the other thing .... Someone suggested that I try doing all of this going to an MSAccess DB (Choke) which I did and glory be!, it worked ... go figure. So I know that what I am doing is at least not out in left field. Of course, since nothing is ever easy, I am having fun now with the DB2 ODBC drivers. Even just trying to create an ODBC Connection gives me the following error. Invalid connection string: SAMPLE Traceback (innermost last): File D:\PROGRA~1\GYNZER~1\lib\python\ZPublisher\Publish.py, line 214, in publish_module File D:\PROGRA~1\GYNZER~1\lib\python\ZPublisher\Publish.py, line 179, in publish File D:\PROGRA~1\GYNZER~1\lib\python\Zope\__init__.py, line 201, in zpublisher_exception_hook (Object: RoleManager) File D:\PROGRA~1\GYNZER~1\lib\python\ZPublisher\Publish.py, line 165, in publish File D:\PROGRA~1\GYNZER~1\lib\python\ZPublisher\mapply.py, line 160, in mapply (Object: manage_edit) File D:\PROGRA~1\GYNZER~1\lib\python\ZPublisher\Publish.py, line 102, in call_object (Object: manage_edit) File D:\PROGRA~1\GYNZER~1\lib\python\Shared\DC\ZRDB\Connection.py, line 159, in manage_edit (Object: RoleManager) File D:\PROGRA~1\GYNZER~1\lib\python\Shared\DC\ZRDB\Connection.py, line 153, in edit (Object: RoleManager) File D:\PROGRA~1\GYNZER~1\lib\python\Shared\DC\ZRDB\Connection.py, line 197, in connect (Object: RoleManager) File D:\Program Files\GynzerWebSite\lib\python\Products\ZODBCDA\db.py, line 155, in __init__ BadRequest: (see above) So now my question to everyone interested is, "Where does a newbie get pointed to in order to start figuring out how to debug this for a new ODBC driver (since we all know that these things are SO standard)(tic)"? Thanks for everyones assistance in getting me this far. Some of you showed that I am really stupid while others of you confirmed that I am not yet insane. >Cold Fusion requires the ODBC datasource to be set up as a "system" datasource. >The ODBC default, however, is a "user" datasource. Maybe on NT Zope needs to >see a system rather than a user odbc datasource. You can test that out easily. Good suggestion, this was one of the first things that I tried out. Same result both ways so I didn't mention it. I'm leaving it on 'system'.

Making non-aware ZClass CatalogAware
by Alexander Staubo 16 Nov '99

16 Nov '99

I have a bunch of ZClasses that aren't descended from the catalog-aware class-wossname. I need to make them catalog-aware. How do I easily do this? Can I export to XML and somehow import them in again? -- Alexander Staubo http://www.mop.no/~alex/ "Only two things are infinite, the universe and human stupidity, and I'm not sure about the former." --Albert Einstein
