[Zope-dev] manage_clone

2002-07-06 Thread Florent Guillaume 

I noticed that CopyContainer.manage_clone doesn't call
manage_afterClone. Is this an oversight or is there a reason ?

Okay, that makes sense :-)

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?

[Zope-dev] manage_clone? (amongst others!)

2000-07-11 Thread Chris Withers 

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
