The ClassSecurityInfo is a convenience to provide a

IntializeClass (among other things) tells the CSI to
apply itself to the class to set everything up, then it
gets *removed* from the class.
I can't tell for sure from your code, but I suspect that
IntializeClass is being called on MyProduct *before* you
are doing your class augmentation -- if you can defer the
call until after you hack it, it should work.
No, I did the InitializeClass() *after* everything else.
So still no explaination. For what's going on.
If for some reason you can't defer the call to InitializeClass,
it should be safe to create another ClassSecurityInfo and apply
it manually, e.g.:
class MyProduct(...):
security=ClassSecurityInfo()
InitializeClass happens...
setattr(MyProduct, 'FileManagement.html', MyProduct.FileManagement)
xtra = ClassSecurityInfo()
xtra.security.declareProtected('View', 'FileManagement.html')
xtra.apply(MyProduct)
That's sort of what I've done now. My code looks something like this::
class MyProduct(...):
security = ClassSecurityInfo()
security.declareProtected('View','blabla')
def blabla():
pass
setattr(MyProduct, 'blabla.html', MyProduct.blabla)
security.declareProtected('View', 'blabla.html')
security.apply(MyProduct)
InitializeClass(MyProduct)
...and now everything seems to be happy.
Thanks for the advice.

Subject: [Zope] Security class attribute
Now in Zope 2.9 I get these warnings::
2006-01-26 14:31:45 WARNING Init Class
Products.MyProduct.Homesite.FilesContainer has a security declaration
for nonexistent method 'FileManagement'
That's understandable because I've coded it like this::
class MyProduct(...):
security=ClassSecurityInfo()
security.declareProtected('View', 'FileManagement.html')
setattr(MyProduct, 'FileManagement.html', MyProduct.FileManagement)
In other words, I create methods after the class has been defined and
squeeze them in manually. Very convenient.
To avoid the WARNING message above I thought I could use
declareProtected() _after_ the the class has been defined just as with
the additional method; but no luck :(
I tried this::
class MyProduct(...):
security=ClassSecurityInfo()
setattr(MyProduct, 'FileManagement.html', MyProduct.FileManagement)
MyProduct.security.declareProtected('View', 'FileManagement.html')
But I'm getting::
AttributeError: type object 'MyProduct' has no attribute 'security'
Which I totally don't understand. To test my sanity I wrote this test
script which works fine::
class _Z:
def __init__(self):
self.z = Z
def declareProtected(self, *a,**k):
print ++declare something+
def foo():
print I'm being called
return _Z()
class A:
security=foo()
def __init__(self):
pass
A.security.declareProtected(foo)
print dir(A)
Which works like you'd expect with the followin output::
I'm being called
++declare something+
['__doc__', '__init__', '__module__', 'security']
What's going on [differently] in Zope? What am I missing?
