Hi, I'm building a custom DataSkin in a Python product, and I need to have different permissions for different properties. I've traced the way this is done in ZClasses but I'm not sure how to implement it in Python or what classes and methods to use. First, there's DataSkinSheet, ZCommonSheet, and PropertySheet. Would a PropertySheet work on a Rack? The interfaces added by ZCommonSheet seem to be aimed at using it in a ZClass, so I guess they aren't needed, but the v_self method added by DataSkinSheet might be needed? Then I need to assign permissions to the sheet. Do I modify the __ac_permissions__ of PropertySheet? I don't think I can use ZCommonSheet.manage_setPermissionMapping as it uses ZClass permissions mappings... or is there another way to do this? Also, to add properties to the sheet, do I need to call _setProperty for each property in the class __init__ method? Or is there a simpler/quicker way?
