I think we need to mention to NOT override __getattr__, if I understand how aquisition works; or at least override it with care, right? What if I want to avoid aquisition sometimes?

Zope Components
by Oleg Broytmann 26 Oct '99

26 Oct '99

Hello! Many times I saw a description of Zope: "Zope is free open-source web application platform..." I want to add two words here: "component-based" and "object-oriented". This sounds a little too buzzwords :) but I am pretty sure this describes Zope nature. While we are on the subject... I use ZTemplates outside of Zope with a great success. Tthere are a lot of documentation on how to use ZTemplates with Python. There are docs on using ZODB, although the docs seems very complex at first glance; may be it is because ZODB is really complex and powerful. In any case I'd prefer to have (along with complex and detailed) somewhat simpler docs with demos and examples. There are some words on using PCGI without Zope and with Python. PCGI Publisher looks simple enough to not need complex docs. But what about Aquisition? I saw some docs on Aquisition on Zope site, but cannot figure out how to use Aquisition with Python. Any help, any tip, any example? Oleg. ---- Oleg Broytmann Foundation for Effective Policies phd(a)phd.russ.ru Programmers don't die, they just GOSUB without RETURN.

creating a ZClass within a Product with Python
by Markus Jais 26 Oct '99

26 Oct '99

Hi folks, I hava a litte Problem. I have a Product written in Python, which inherits from ZClasses. Now I want to add a ZClass to the Product with Python. my first thougt was, to simply put "manage_addZclass(id)" in the Constructor, but nothing happened (no ErrorMessage, no ZClass was visible, when I clicked on the Product in the management screen) Does anybody have an idea how to do this. Or an url, where I can see an example. Thank you very much! Markus Jais

Can't rename a CatalogAware ZClass Instance

It seems that I can't rename/copy/paste a CatalogAware ZClass Instance. Is this true? If so, is there a workaround? Kam

You'll need to build ZOracleDA on the Sun. For this, you'll need the Sun version of the oracle client libraries. I don't think Oracle make their client libraries available separately.

Oracle's a bit more finicky, and wants a bunch of files in $ORACLE_HOME to be present before it will play nicely. At a minimum, you'll want $ORACLE_HOME/network/admin/tnsnames.ora, and quite possibly a number of the $ORACLE_HOME/.../mesg/ directories.

SQL queries?
by Ethan Fremen 26 Oct '99

26 Oct '99

Zopistas, I'm kinda stressing on this one... Is there any way I can do SQL queries to a remote machine without having to have a DA and Zope instantiated on that machine? I just need to run queries, nothing more than that. (the machine is HP-UX and the database is Oracle 8.0.5.1) Thanks tremendously, -- Ethan "mindlace" Fremen you cannot abdicate responsibility for your ideology.

No, as they'd be different architectures. If you had a Sun Oracle installation, you could build it against that on the web server and still access it remotely (probably). -Dom -- ********************************************************************** This email and any files transmitted with it are intended solely for the use of the individual or entity to whom they are addressed.
