Re: [Zope-dev] is an object in a folder

24 Aug 2004

      ...
from Acquisition import aq_base
...
    def hasObject(self, id):
        """Test if an object is in the current object.
        """
        if hasattr(aq_base(self), id):
            return 1
        return 0
It would be nice and faster but it doesn't work for non-subobjects
attributes. For instance your hasObject('meta_type') or
hasObject('isPrincipiaFolderish') would return true.

The goal of hasObject, as I see it, is to check if the object is
considered a real subobject. That's what BTreeFolder2's does.
...
The same idiom is used in ObjectManager.checkValidId, FWIW.
Yes but the use case is slightly different IMHO.
