I hit same problem some time ago - I needed to made my own accessor.
What I done is getter in ZODB, and my property definition looks like:
{
'id' : 'trade_name',
'description' : 'Trade name of resource',
'type' : 'string',
'mode' : 'w',
'acquisition_base_category' : ('object',),
'acquisition_portal_type' : Expression('python: []'),
'acquisition_accessor_id' : 'getTradeName',
'alt_accessor_id' : ('Base_getTradeName',),
'acquisition_mask_value' : 1,
'default' : '',
},
And Base_getTradeName is script in ZODB, which is doing all magic. That
way I've got nice getTradeName method on objects, which is
configurable using Base_getTradeName.
Regards,
Luke
