[Zope-CMF] Where do CMF get the "Creator" variable from ?

[Grégoire Weber]

Hi Gitte,

As I (as Newby) understood portal_membership you have to feed getMemberById
with the *id* of an object and not with a (the Creator) property of the
object. So try this (not tested):

   <dtml-let created_by="portal_membership.getMemberById(id)">
      <dtml-call "REQUEST.set('realname',created_by.real_name)">
   </dtml-let>

I know the following works with getUserName(), so try this first if the
above does not work:

   <dtml-let created_by="portal_membership.getMemberById(id)">
      <dtml-call "REQUEST.set('realname',created_by.getUserName())">
   </dtml-let>

If you try to get the Member of an object not created by a Member (e.g.
DTML method) getMemberById returns None.
So you probably have to check this case to avoid an AttributeError exception.

   <dtml-let created_by="portal_membership.getMemberById(id)">
      <dtml-if created_by>
         <dtml-call "REQUEST.set('realname',created_by.real_name)">
      <dtml-else>
         <dtml-call "REQUEST.set('realname','n.a.')">
      </dtml-if>
   </dtml-let>


Hope it helps,

Greg
