Re: [Zope-dev] _p_deactivate() and _v_ variables?

2003-10-09 Thread Florent Guillaume
I would argue that a better plan would be to only use _v_ vars for completely disposable data only. The application should expect that this values will be gone at any random time, not just at transaction boundaries. I agree with this. How do we go about find code that uses the

Are there any plans or is there any interest in supporting the Creative Commons Licenses for metadata in Zope-documents? Has there ever been any talk of such a product? Examples of applications with built-in CC support: http://creativecommons.org/technology/ccapps Greets, Wouter Vanden Hove

[Zope-dev] relations in objects

2003-10-09 Thread Jason Corbett
Hello Zope developers, I'm a newbie (sorry most people have this curse at one point or another). I have read the zope book (or at least most of it), and the zope developer manual. I can't quite figure out how to have relationships between instances of classes in the database. Let me first

Hi Jason, I am not a zope developer, I am a semi-new user who started with zope coming from the same mindset as yourself. One of the biggest challanges(at least for me) is to wrap your mind around object oriented programming. The zope database is an object oriented database. This means that you

Thanks for your reply. I've actually been thinking in an object oriented form for a while. I've looked at implimenting this project in Java using either prevailance or a object persistence model that mapped to a RDBMS. I like the idea of zope, so maybe I should clarify my question: How does an

I'm sorry for my ignorant use of the terms relation and relationship. I'll try to use the terms more appropriately in the future. I think I understand where I've become confused. In many of the persistance mechanisms I've looked at references to other objects were handled specially, and had
