Thinking Outside the Box

Connections that won't, upgrades that can't, hot syncs that don't, standards that never are, wireless transmitters radiating who knows what. ... Hephaestus was the Greek god of fire and crafts, which is to say technology. Tellingly enough, he was born lame. His greatest creation was Pandora. Hephaestus sent her -- at his father Zeus's request -- to plague mankind. She was beautiful. But she sought knowledge. So she opened up a box that had been entrusted to her. Out leapt the plethora of ills that afflict humanity. All that was left inside was hope. ... http://washingtonpost.com/wp-dyn/articles/A23937-2001Mar18.html (found on /.) ... "There'd be different legal categories of software. If you want to rush it to market, and have first-mover advantage and see what happens, fine. You could label it creative software. But much of your code will be open to the public." If you want to build a business empire, however, and you want the government to throw itself into protecting your copyrights, in Lanier's scheme you would then have to label your product "firmware." "If you see this thing is taking off, you have the right to say: This is no longer creative software. This is functional. This has utility. "But once you do that, you owe me a buck every time it crashes." Oleg. ---- Oleg Broytmann http://phd.pp.ru/ phd(a)phd.pp.ru Programmers don't die, they just GOSUB without RETURN.

Re: [Zope] ZClass direct variable access

Phill Hugo writes: > Is there a way to access property sheet variables from a zclass method > without knowing which property sheet it is contained within. If you only want to read them: they are exposed as attributes of the Z Instance, i.e. you can use "getattr" to access them (as your property is an expression). For constant access, you could use the attribute access syntax. I do not know a way to change properties without the specification on the property sheet. Dieter

Design Help
by Kenneth Ellested 20 Mar '01

20 Mar '01

I'm trying to design some classes in Zope based on a SQL scheme. [Table] Product ProductID: Integer Description: String [Table]: Attributes AttributeID: Integer Description: String [Table]: AttributeValues ProductID: Integer AttributeID: Integer Value: String Which should produce a layout like: Product1 Product2 Product3 Product X Attribute1 Value Value Value Value Attribute2 Value Value Value Value Attribute3 Value Value Value Value AttributeX Value Value Value Value How do I implement this as Zope Classes. The data is mostly static, and theres only a few changes to the attributes over time. Regards

ZMySQL Database connection trouble
by ghaley＠mail.venaca.com 20 Mar '01

20 Mar '01

hi, I am trying to add a ZMySQL database connection. Everything seems to go ok, but when I try to view the Products Management, it shows the ZMySQL as a broken product, when I view it, there is an error that says: ImportError: /usr/lib/python1.5/site-package/MySQLmodule.so: undefined symbol: uncompress If I try to go the the /opt/zope/lib ,etc. directory and start the db.py connection directly, python db.py, i get the same error. If someone could provide some direction on how to recompile the .so file so that it can handle the uncompress problem, I would be most grateful. btw, i've read the various howtos on the zope.org site, and i didn't find this particular problem there. I am running MySQL 3.23, the most recent release of zope, on linux 2.2 running slackware 7.0 Many thanks. ciao! greg. Gregory Haley DBA/Web Programmer Venaca, LLC

Re: [Zope] Installation Probs
by Luke Tymowsk 20 Mar '01

20 Mar '01

Hello, > Actually, that's what happens on my Windows Zope as well. > Can you try another machine? I had that happen when I was trying the 2.3.0 betas. The Win32 Zope installation creates some Registry entries. One of the entries points at the location of the service code. If you uninstall Zope it does not remove those entries from the registry. If you later install another version of Zope in a different directory, Zope will fail silently trying to start the service. how to fix? edit the registry and remove the offending references. Install Zope again, and all will be sweetness and light. Luke

More ZClass oddities
by John Morton 20 Mar '01

20 Mar '01

I'm experiencing a few problems with some ZClasses and catalogs under 2.2.5 - they look like bugs, but they could be a result of a clue shortage on my part. The first one relates to a ZClass that uses Object manager as a base class. When instances are created, a ZCatalog is automatically added (cusiously, I don't need to specify that ZCatalogs can be subobjects for this to occur). As I'm in the development stages, I let Z Seach Interfaces be subobjects of my ZClass but when it comes to adding a serach interface instance, the automatically created catalog isn't listed as a searchable object - and nor is any other catalog I add. The second problem relates to ZClasses created as a subobject of another ZClass. This means that those items can only be created inside an instance of the parent class (the desired effect), but it also seems to mean that those object types don't show up in the type list of the 'Find Items To Catalog' tab in the catalog in the same folder. So... Bugs? Or is there something I don't know? John
