Hi I am trying to create a wizard in my portal to enable users to store information. In addition to the features of the already existing Document Wizard, I would like my Wizard to have more features like information about the category of the document, etc. I created a file called "Userdocument.py" with a method "addUserdocument" which will be called to add a new document. I have also added the new entry to the PTKBases & PTKDemos __init__.py. But as soon as Zope starts, it gives this error 2001-01-25T06:07:07 ERROR(200) Zope Couldn't import Products.PTKDemo Traceback (innermost last): File /export/usr/local/Zope-2.2.4-src/lib/python/OFS/Application.py, line 397, in import_products (Object: string) File "/export/usr/local/Zope-2.2.4-src/lib/python/Products/PTKDemo/__init__.py ", line 159 PTKBase.Userdocument = Userdocument ^ SyntaxError: invalid token Could anyone please tell me how to create custom wizards and to register them? Thanks. Priya

Aethera server and functionalities + ZOPE
by Nicolas Pettiaux 25 Jan '01

25 Jan '01

Dear Mr Shawn, THank you for your recent mail. As I said i a recent message, in order to move my institution towards open-source products and related services, I need the appropriate tools and services. For me, the KDE applications, aethera and kivio, you are developping, are such tools we ( = the community + I) have long expected. I need a groupware solution (that can use our LDAP directory) closely linked to shared calendars, shared folders, connection to PIM (IPAQ and Palm V), email lists ... As the ICT manager, I have a rather strong influence on where we will spend our money and how ( for me, this is rather buying services we can rely on than products that are closed and that will soon appear not open enough, and too limitative) We are decided to use more and more ZOPE as a backend and server. have you considered using ZOPE as the server , for example for the shared calendars, for aethera ? How coul I help you considering ZOPE for such a use : this would be really convenient for us as it would mean we could integrate aethera and the web based calendar+groupware+workflow we are considering. I suppose such requirements are similar to the ones many companies and institutions like mine have. Maybe, all these institutions could team up and support you along these lines. For me a VERY important point you satisfy, and for which once again I want to thank you, is that the application be free software. Some more questions: 1/ which standards are you following for example for the calendaing features or the taks and appointment requests ? 2/ will the application be compatible with Evolution ? 3/ You say > > Python will be woven into all of our applications as a scripting > > component. It isn't there yet, but it will be. For kivio and aethera, what are your plans (release dates ) ? 4/ How can I help you get further ? - Try and collect money, - find people/teams/developpers especially KDE who could help you and your company - or shoudl I say kompany at developping or selling local support ? I am better at that - convincing people and finding money - than at writing applications so I'll stick to what I am best of. Best regards, Nicolas Pettiaux -- Nicolas Pettiaux Avenue du Pérou 29 B-1000 Brussels

Hi: I need to report my all "CDClass" in one pdf document. For do that i want to use the reportlab libs, but i don't know how i can access to my all "CDClass" with a External Method. I have a solution but i think that isn't the best: list all "CDCLass" with a DTMLmethod and pass that list to the my ExternalMethod. My question is: what is the best way for doing that task? Thanks Very Much in advance Have a nice day. JoRgE

Access Problem - external method and aquisition
by Bill Welch 24 Jan '01

24 Jan '01

Some time ago, I set up a site with SiteAccess and ZClient to pass through a request to legacy php a la Mamey's 'Serving PHP/Perl from Zope'. Works great, lasts a long time. I recently added Membership and restricted access to the folder. The AccessRule works and publishing of index_html starts, as before. Upon attempting to execute the external method that contains the ZClient, however, I get a basic auth window. The problem seems to be that aq_inContextOf returns 0 for the external method when it's called from Products/LoginManager/LoginManger.py:84, thereby causing allowed to return 0, and raising the unauth exception at AccessControl/ZopeSecurityPolicy.py:183. Works fine for DTML methods called within index_html. Any ideas? Zope 2.2, linux, PTK 0.9, Membership 0.7.8 Bill.

To clarify, W2k is probably pretty reliable now for the desktop, but the servers have a way to go. In addition to reliability issues, the resources required to do the same functions on the 2000 products (w2k, office 2K, access 2K) are much higher than the 97 and 4.0 versions. MS can't even keep their own sites going: http://www.zdnet.com/zdnn/stories/news/0,4586,2677896,00.html?chkpt=zdhpnews 01 Now I don't bash MS for a living, just as a hobby. They've been sliding steadily downhill since the 4.0 release. I provide computer services on MS and Novell networks for a living. I would not consider putting W2K servers into production until they are stabilized and still would not do so unless my client are planning a hardware upgrade as part of the process. We've seen too many black screens of death with W2K servers. The clients do appear more stable, but why sacrifice performance in a business environment when you gain nothing? I've used 4.0 without a crash for years. Why switch? It's faster and does everything I need. It will be interesting to see the Unix command-line loving community's reaction when MS releases their text mode server product. This will certainly interest the mouse-phobic. If I want USB for multimedia solutions, I'll probably do it under BeOS. Then again, I'll probably use firewire. (which should've been in windows instead of USB from the start.

Below - I have a database called test that I can connect to - but no tables called test: mysql> show tables; +----------------+ | Tables_in_test | +----------------+ | bigstuff | | groups | | shop | | t_chunks | | t_largeobj | | user_group_map | | users | +----------------+ 7 rows in set (0.00 sec) mysql> select * from test; ERROR 1146: Table 'test.test' doesn't exist As you can see - you would get the result you described if you did not have a table defined.
