[Zope] turning off inheritance
I am working on generating a directory from Zope objects. There is a folder full of units (other folders). These units contain people (more folders). Units and people both have contact information stored in their properties. How do I detect if a person has, for example, 'contact_email' set? I've tried dtml-if "_.hasattr(this(), 'contact_email')" It succeeds if the person doesn't have contact_email set but its unit does. I've also tried variations of dtml-with ... only, with no success. Any pointers? Where could I have found the answer to this on my own? Thank you. --kyler ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )

It works great from DTML. Now that I know what to seek, I found a couple of old messages that reference this. I'm still honing my ability to get Zope clues. Thanks for the quick and effective answer! --kyler ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )

Now that I know what to seek, I found a couple of old messages that reference this. I'm still honing my ability to get Zope clues. I got it form exactly this mailing list. I just monitor the list form the very beginning, I forward many important message to Russian Zope list, discuss this information, etc. Nothing special. Often I ask questions here. Of course I do digging Zope sources from time to time :) Oleg.

Any pointers? Where could I have found the answer to this on my own? I don't claim to know the complete answer, but one approach could be to do a comparison something like: (warning code untested): dtml-if "_.hasattr(this(), 'contact_email') and contact_email != PARENT[0].contact_email" another approach is to set contact_email by default and test for emptiness dtml-if "contact_email==''" dtml-let contact_email="PARENTS[0].contact_email" hth Rik ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )
