Greetings, I am setting up an application that will have a project object/class, and each project can have multiple tasks, multiple deliverables, and multiple team members. How best to represent this in Zope ZClasses?? As i see it, the options are: 1. use ZClass sub-objects. This seems unstable or not well liked by the community. OR 2. give each task, deliverable, and team-member class an attribute of project_id to bind them to the parent project class (like a foreign key relationship in RDBMS's) OR 3. use python and create "real" classes. this would require me to spend more time learning/building the class libraries, but if it's the much preferred solution, i will. Any thoughts are much welcome. Thanks, mark -------------------------------------------------------------------- mail2web - Check your email from the web at http://mail2web.com/ .
