[Zope] Re: Creating a New Object Type - Use ZClass or Pytho

[ej@ee.duke.edu]

Thanks for all the responses.  He he... I should have known better, though.  Of the first three responses from Anthony, Michel, and Kevin, I got 3 totally different responses.

If I had known more about XML, I probably would have used that approach, but I'm gonna focus on Zope for the moment.  And of the other two, I chose to use ZClasses simply because I felt a non-Python person would have a better chance of fixing the site in the future.  Still, I've added some Python routines when my novice DTML skills drag a 1 minute function into taking 30.

So I've gotten my Publication class written and it works - but minus a few features.  

1.
The main problem is that I haven't been able to get ZCatalog to search my author list (a line property) correctly.  I can search on any other property accept this one.  My feeling is that it is treating the entire list as a single property instead of breaking the list items out as individual authors.  Does anyone have any insight into this?  

For the moment, I have a python function that searches the author list.  Simple, but I need to figure out how to do it in ZCatalog.

2.
Also, I haven't figured out how to make a selection property using ZClasses.  I read a post about adding a selection_list (or something like that) property to the propertysheet.  This worked, but the selection_list property was also visible on my objects property sheets - not too pretty.  I wanted to have multiple selection list also, but this seemed impossible.  For the moment, I've hard coded the list in DTML.  Any better way?

thanks for everyone's help,

eric
