Chris, I'm sorry to hear about your challenges. I've had some myself. I think you're being bitten by a bug which prevented manage_clone from working in a lot of situations, but is solved in 2.2. The problem was that when a new object was placed in a container, it didn't get a _p_jar attribute until the database transaction was completed (which is standard practice). But _getCopy() depends on a _p_jar. So if you tried to copy an object into an object which has just been placed in the object hierarchy (a common thing to do), _getCopy() failed. To fix this, change ObjectManager._setObject() to this: def _setObject(self,id,object,roles=None,user=None, set_owner=1): v=self._checkId(id) if v is not None: id=v try: t=object.meta_type except: t=None self._objects=self._objects+({'id':id,'meta_type':t},) # Prepare the _p_jar attribute immediately. _getCopy() may need it. object._p_jar = self._p_jar self._setOb(id,object) object=self._getOb(id) This will probably work fine in 2.1.x. manage_addProduct[] gives you access to the object factories. I wonder if it would be clearer if you could use "productFactory[]" as a synonym? Shane Chris Withers wrote:
I was going to title this 'I should give up using Zope' but I thought I'd give it one last go...
Yesterday's 6hrs failing to do a tree-walk-and-copy in DTML failed, so I thought I'd try in an external method today...
..well, that proved to be just as stupid.
Okay, firstup, has anything happened on this issue: http://zope.nipltd.com/public/lists/dev-archive.nsf/ByKey/37C533B80F56E22A
Basically, it seems like doing anything with ZClasses in python (an external method in my case) is likely to lead to suicide on your part.
How shoudl I be instantiating one?
Secondly, AFAIU, the following should copy o and put it in the folder object 'where' with an id of 'new_id':
where.manage_clone(o,'new_id')
It does, for DTML Methods, but for anything else I get:
Error Type: AttributeError Error Value: 'None' object has no attribute 'importFile' (the traceback is in a PS ;-)
Why? How should I be doing this?!
Lastly, in the following: where.manage_addProduct['OFSP'].manage_addFolder(id,title)
What does the manage_addProduct['OFSP'] actually do? In what way does the above differ from: where.manage_addFolder(id,title)
...which works just fine for me...
Hope _someone_ can help,
Chris
