Is there any reason why an object cannot be contained in more than one
Folder in the ZODB?
Apparently what I'm talking about is very similar to hard linking in
UNIX...
I can't think of any reasons why this would be bad but I can't think how
to implement an 'Add hard link to this object' function
Recently, several posters have reported strange "AttributeError __call__"
exceptions.
The most precise was a report by Oleg Broytmann:

Hi Folks,
After the ZPatterns chat on Friday, it looked like a few people were
thinking of getting into Peter Coad's book "Object Models: Strategies,
patterns and applications".
I've just received my copy, and I'll be starting it later today.
I intend to use a Wiki to record my observations a
Brian,
This is an excellent bug analysis. I suggest that we create a new
PyCallable_Check function that works in the presence of wrappers,
perhaps called PyCallable_CheckW(). If it is placed in Acquisition.c
then cDocumentTemplate.c will have to #include "Acquisition.h". Then
we need to replac

On UNIX symlink is not a link - it is a text file, that contains a name

Hi there,
I see that the 2.2 still has this annoying, and seemingly completely
unnecessary minor change in the tab order:
Tabs for folder in 2.1:
Contents View Properties Import/Export Security Undo Find
Tabs for folder in 2.2:
Contents Import/Export Properties View Find Security Undo Ownersh
Hello,
What is the easiest way for me to get ahold of the Application object at
run-time?
I am writing a Product that needs to access some things in the
Control_Panel, and need the app object to get there.
I know how to do it given a reference to an object in the ZODB
(getPhysicalRoot(), etc.),
I'm not sure I understand. What is AppSingleton? What does the
Instance() method do?

Sorry I wasn't clear enough. The Singleton is a design pattern from the

So it's kosher then to reimport the Zope module and use app() in a
constructor method, Shane? I was always afraid it would do something
horrible.

You certainly should not call reload(Zope), but the semantics of import
are smart enough to only execute the module th

I am simply trying to "upgrade" a persistent instance of a Python class.
For instance:
class MyClass:
def __init__(self, id, title=''):
self.myAttr
How about a class attribute?
class MyClass:
myAttr2 = 'Default'
def getMyAttr1(self):
return self.myAttr1
def getMyAttr2(self):
return self.myAttr2
If myAttr2 needs to be a ZClass instance, just grab it inside the class.

I'm using a "walk the tree" method of updating instances of a Python

Probably from the folder you referenced it from and then normal
