ZEXP woes with INSTANCE_HOME'd sites
by GimsMail 16 Nov '02

16 Nov '02

Hi all, I have two Zope 2.6 sites (this happens with 2.5 too) both running EXACTLY the same products and CMF 1.3 the only difference being the one Zope is an INSTANCE_HOME installation and the other a standard Zope installation (both in Win2K). I have tested this with fresh installs too, just to make sure, so I guess it will be repeatable by anyone else. When I export a CMF Site from the one and try to import it to the other I get broken Portal Folder icons and the site does not work (gives a tuncUnitID attribute error somewhere in the actions box). This happens consitently and with Zopes on the same machine and different machines, the only differentiator being INSTANCE_HOME or non-INSTANCE_HOME. This happens both ways (INSTANCE_HOME to normal and other way round). I am not sure if this is only a problem with CMF Sites, but have not found this problem with other products. Am I doing something wrong, is this a bug and should it be put in some collector. Is there a known workaround? Thanks Etienne

aquisition and security changes?
by Clint Brubakken 15 Nov '02

15 Nov '02

I wrote something in zope 2.3 and upgraded to zope 2.4, in which I had a base Page Template viewable by a community_manager role, In a subfolder of the one that contains that template I have a user folder, that defines a user that has that 'community_manger' role. In 2.4 the user could view it, in 2.6 they can't has something changed? -- Clint Brubakken <cabrubak(a)inetic.com> Inetic Web Development

ZClass Methods and Namespace issues
by Ted Pollari 15 Nov '02

15 Nov '02

I'm having trouble with what must be a namespace issue involving python, DTML and ZClasses. Using Zope 2.6: I'm working on a ZClass designed to allow for the easy creation of a web-based survey system. My "Question" ZClass is defined in a product in the Zope products directory. Within each instance of the Question ZClass (which are folderish) there is a dtml document called FormPiece (created by the Question Class constructor) that includes a small snippet of html and dtml. The html is form inputs which get their name value from a dtml-var tag that calls a python-script method. That python-script method is defined in the Question Class itself. If I view the FormPiece item itself from the management interface, it all works fine and the python-script is found and works as intended. Problems arise when I am calling the FormPiece in a different way... When I call another python-script, named "ReturnFormItem" that is a method of the Question Class on one of the Question Class objects an error is generated... Here are the contents of the ReturnFormItem: ############### print "" print context.FormPiece() Return printed ############### Now, when this script method is called on one of the Question Class instances, this returns a key error because FormPiece contains a dtml-var tag call to the method "ReturnSQLId" which is a method of the Question Class. Interestingly, though, the call to the same ReturnSQLId method in the ReturnFormItem script works fine. So it seems to me that by calling context.FormPiece() and then trying to call the ReturnSQLId inside the FormPiece document is being called without the "normal" namespace... Correct? If that is the case, how do I get the call to context.FormPiece() to use the same namespace as if I were calling FormPiece directly, such as from a URL? Or am I completely confused about all this? Thanks is advance, -Ted

session problems
by Eddie Mönch 15 Nov '02

15 Nov '02

We have used the session object to store temporarily data in. But it happens to be that it works not on a few clients (all working w/ MSIE). The session object on these clients are only available for the same site, but by changing the site the object is lost, though the session data container still has the objects in storage. Has anyone experienced something similar and/or a solution?

I have a similar additional | newbie problem: | | FolderA | ...FolderB | ...FolderC | ......FolderD | ......Method1 | | Method1 (in FolderC) has no problem, of course, doing a <dtml-with FolderD> | | I cannot figure out how to <dtml-with> to get from Method1 (in FolderC) to | code in FolderB. FolderB is parallel to Method1's parent (FolderC). Take look at code in attachment. Here is nice recursive access method in pure DTML. May it help you. It is from early Zope mailing list archive and I use it. Regards J. Lukesh

Re: [Zope] error-handling product?
by Dylan Reinhardt 15 Nov '02

15 Nov '02

Yes, thanks... I have quite an extensive set of DTML standard_error_message files. I've been e-mailing myself tracebacks for quite a while now. Now I want to do stuff I wouldn't use DTML for, like batch mailing and significant filtering. If nobody has heard of such a product, I guess I'll get to work making it.

Product Refresh clears Persistent attributes
by John Ziniti 15 Nov '02

15 Nov '02

This is something which has "Just Worked" for me in the past as I have developed Python Products. But now I am stumped. I have two Products. Product #1 is a: (Persistent, ObjectManager, PropertyManager, Implicit, Item) and contains other objects of type: (ObjectManager, Implicit, Item) Product #2 is a: (Persistent, RoleManager, ObjectManager, PropertyManager, Implicit, Item) which contains objects: (RoleManager, PropertyManager, Implicit, Item) The two __init__.py files are nearly identical Attributes (strings, etc.) on contained objects in Product #1 are persistent across Product refreshes, while attributes of contained objects in Product #2 are all flushed on Product reload. The only differences I can see at this point are the base classes, and the fact that Product #1 does not directly store it's sub-objects, but contains a folder which contains the objects. Should that make a difference here? What's going wrong? Thanks in advance, John Ziniti
