initialize()
by Kevin Howe 04 Sep '00

04 Sep '00

I've noticed that some ZOPE Python Products define an initialize() routine in their __init__.py file and some don't. From what I can tell it is not really needed, but simply offers a more organized way of registering the Product. Is it good practice to define initialize(), and if so, why + what does it do? kh

Retrieving ROWID's from Oracle crashes python
by Ayhan Ergul 03 Sep '00

03 Sep '00

Zope has been dying silently with the following configuration: Zope version: Zope 2.2.1 (binary release, python 1.5.2, linux2-x86) Python version: 1.5.2 (#10, Dec 6 1999, 12:16:27) [GCC 2.7.2.3] System Platform: linux2 ZOracleDA-2.2.0b1 Oracle 8i (8.1.6.1) Not being able to figure out what the problem was, I replicated the site on WinNT zope. Crashes repeated there too with NT popping up a dialog box telling that python.exe could not read some memory location. I tracked the problem down to a query that returned ROWID's from an Oracle table. Upon rewriting the query to eliminate the need for ROWID's, crashes went away and Zope has been up since. Anybody had a similar experience? Is it a problem with DCOracle included? Ayhan

My Apologies
by Jonathan Desp 03 Sep '00

03 Sep '00

Hi Zope Community, I'm sorry about my emails, my friends said me that I was rude. I learned and I hope to be able to don't re-do it. It's only an image, I mean, I know how to give in return, when people give me something. I think it would be great to get a personal assistant. If you know someone beside you, just say that he could be useful at Atomasoft, I have several and clever ideas on how to make money. Plus 4 projects that will make more money. NanoSoft is alot more complex then Zope itself, and we are building it presently, with 8 programmers. Very truly yours, <><><><><><><><><><><><><><><><><><><><><> Jonathan Desp Chairman and CEO, Atomasoft Inc. Matter will become software http://www.atomasoft.com/jonathan <><><><><><><><><><><><><><><><><><><><><>

Anyone has LoadSite please?
by Peter Hansen 03 Sep '00

03 Sep '00

In posting this I hope to stave off a flame war. I've downloaded loadsite-1.4.0.tgz from zope.org (without problems) and have sent an email separately to Mr. Desp so he can stop pestering the list for it. (The email contains free advice on etiquette, too.) -Peter > > Jonathan Desp wrote: > > > Anyone here would like to send me the program loadsite via email, by > > > attachment, please? > > > > Why not just search the mailing list archives? > > I did, there is no attachment of loadsite... do you have it in your > computer? why don't you email it to me right now, and then I'll stop to > waste my time. please, email me the program. > > > > > > I'm waiting a reply from Itamar since 3 weeks, and I cannot continue to > make > > > B2BEmerging.com and MEMSCenter.com > > > > Maybe Itamar has his own work to do?! > > I think so. but why you are saying that? it's desctructive.. > > > > > Chris > > > > > --__--__-- > > Message: 12 > Anyone can give me LoadSite by email please?

Volunteers for Atomasoft?
by Jonathan Desp 03 Sep '00

03 Sep '00

Hi, I don't know, but I'm searching a helper. I cannot pay you yet, because Atomasoft is still very little, very small. I have another team constructing NanoSoft O.S., it's a future operating system for the revolution of the miniaturization industry (MEMS,Nanotech). I'll be able to pay people in the future, but not yet. I tryed several times to understand Zope. But like Bill Gates said in an interview, The Open Source world is full of non-compatible system. So everyday, I'm trying to work with Zope, but I'm getting big angryness. I would prefer to see a volunteers, that know this Zope. So that me, I can focus on my businesses. I'm more a business man than a web programmer. --Jon Atomasoft: MEMS Center, B2B Emerging, MEMS Conference, Photonic Software, NanoSoft O.S., MEMS Software, Design/Simulation, in Palo Alto.

ZCatalog problem!
by Kevin Howe 03 Sep '00

03 Sep '00

Hi, I have a Folderish class (FClass) and I am trying to write it so that when an FClass object is added in ZOPE, it will automatically create a ZCatalog object inside itself. I attempted to do this in the manner I had successfully done this before with other object types: # handle represents the new object to be added with self,_setObject(id, handle) handle.manage_addZCatalog('CatName', 'CatTitle, None) But this doesn't work. I then did some testing with DTML using the following method inside a Folder: <dtml-call " manage_addFolder('FolderName') "> <dtml-call " manage_addImage('ImageName', '') "> <dtml-call " manage_addZCatalog('CatName', 'CatTitle', _.None) "> The new Folder and new Image were both added with no problems. This was what I expected since the "manage_addFolder" and "manage_addZCatalog" methods are inherited from OFS.Folder.Folder. The method "manage_addZCatalog" however, doesn't seem to have been inherited for some reason. I can add a ZCatalog using the "Add" List, but not programmatically for some reason, as I can with Folder and Image (and probably most other object types). Anyone have the faintest clue why this might be? Thanks, kh

SQL-Session 3.0 -- session won't be writen to database
by Andy Pahne 03 Sep '00

03 Sep '00

Hi, I'm playing around with SQLSession-3.0 When I do something like the following: <dtml-call Session> <dtml-call "SESSION.set('foo','bar')"> <dtml-var "SESSION['foo']"> my session variable "foo" renders as I expected. But when I move to another page my session-variable "foo" is not available. Creating a session works perfect and the next page remembers about the created session and gives me the correct name, but no session-variables. I checked the database and there werde no entries in my session-data table. Am I missing something like <dtml-call "SESSION.nowWriteItIntoTheDatabase()"> or what? Andy Pahne ap(a)big1.de
