Re: [Zope-dev] Please HELP: Nested ZClass, Nested instance

Title: Re: [Zope-dev] Please HELP: Nested ZClass, Nested instance

Hello Karl, who has same name as me:-)

Yes, I can create child zclass nested in parent zclass according to the Howto on management interface.
And the zclasses were inherited from Object Manager and Catalog aware class.

But still I can't do it programatically.
If you know how to do it, your advice would be appreciated.
(Due to the schedule, I decided to just go ahead according to Rik Hoekstra's advice)

I found a interesting fact.
When we access some ZClass in the product folder, the typical syntax used is(in DTML)
    this().Control_Panel.Products['MyProductFolderName'](DTML)
    self.Control_Panel.Products['MyProductFolderName'] (Python)

This syntax seems to say that Products is a dictionary object of Python, because 
we can access each product folder by key.
But when I try this,

this returns just "1"
But interestingly, 

        - or - 

returns expected results.

Should I think "Product" folder under "Control_Panel" to be a kind of dictionary object?
Thanks a lot
Karl

I had some hassles with this recently.  There's a HOWTO at:

http://www.zope.org/Members/gtk/containers

Can you create the child zclass from the manage screen inside the
parent zclass?

Does the parent zclass inherit from ObjectManager before any other
superclasses?

Yes, but if people _want_ to create superuser objects that can do anything
they should be permitted to. As long as the superuser doesn't make really
stupid objects they shouldn't get bitten.

The problem is that the new security model should have more handholding
to go along with it.
Perhaps the superuser should be changed to the name "usermanager" or
"permissionsmanager" or something like that and a default superuser
with the behaviour every actually expects the superuser to have be
created as well.
As it stands now you need _two_ "superuser" type users, so they should
both be created automatically instead of having to create one of them
manually afterwards.

Also I still maintain that, as well as the "Take Permissions" permission
that a NONE permissioned method should be available for ownership
transfer, that you can "offer" an object to someone and they can later
on "accept" it when they log in. (Like the moderation concept in Squishdot)
This is needed for cases where a site manager has say a hundred projects
going on under their Zope server. When one of the projects changes
project leader and leaves they have to transfer ownership to their
successor, but they _can't_ because their successor is _less_ authorised
than they are and can't "take permissions".
In this case they currently have to petition the person running the site
to change all of the permissions for their project over. This is a waste
of everyone's time and completely unecessary.
With a challenge/response transfer of objects you have complete security
maintained (especially if you allow the person accepting the ownership
to preview the object prior to their decision to accept it.)
It's more work to set up this system because nothing in core Zope uses
this type of messaging once people login, but it's a much broader and
usable means for ownership transfer without losing any security.

[Zope-dev] Zope-2.2.0a1 and Products (SiteAccess)

2000-05-22 Thread Carl Robitaille

Hi everyone,

After the announcement that the version 2.2.0a1 of Zope was out, I
decided to go for it. I was able to make it running in no time.

I tried to install two different Products: ZMySQLDA and SiteAccess.
The first one worked fine the first time. But I get an error starting
the server (running PCGI) when the product SiteAccess 1.0.1 is
installed. I have a feeling that it has to do with the new Ownership
feature in Zope. But since I'm a Zope newbee I haven't been able to
locate the exact problem (sorry about that) and so I might be wrong.

Has anyone else experienced that kind of problems? Should I go back
to 2.1.6? Actually, the reason I went for 2.2.0a1 is because of the fact
that upgrading 2.1.6 to 2.2.0a1 didn't seem trivial because of the
ownership thing.

Any comments are welcome. Thank you for your time.

Carl

P.S. I attached the output that I get when I try to access Zope content
via PCGI.
