Composite Objects?
by Jeffrey E. Forcier 12 Apr '05

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hey all, I'm attempting to use mostly-vanilla Zope to implement an intranet here at my office, but am finding it difficult to use a 'feature' that I imagine should be possible. I've created a template for what ideally would be a single object/class type, containing multiple different kinds of Zope objects, and want to be able to clone new copies of that template as one can do with the existing Zope objects (e.g. as one would add a new File or Folder). The template currently consists of a typical index_html ZPT, a Formulator form, a small collection of Python Scripts, and two generic Files which are the CSS and JavaScript includes for the ZPT. These are all contained in a normal Folder object. The ideal situation is that I want a single object, which has various data fields (storage location is not important at this time) that are manipulated with the above objects--the ZPT+files generate a form page, using Formulator for rendering and validation, and the Python scripts for various other tasks, including the eventual input processing. And, as stated before, I need to be able to instantiate new copies of this object. Now, I first looked at ZClasses (which according to the Zope Book is exactly what I want), but it appears that each ZClass instance shares the 'methods' in the ZClass definition--so that if I wanted each individual object to add fields to its own Formulator form, it couldn't. On top of that, I read and (mostly) understand some of the recent discussions here about possible deprecation of ZClasses, making it even less of a desirable option. I then looked at CPSSchema, but what appears to be its homepage on zope.org cannot be accessed even after one creates an account on the site; furthermore, what little I was able read about it suggests that it too is not quite what I'm looking for. Ditto for Plone's ArchTypes (plus I'd *rather* not have to use Plone, as this intranet is not really going to be a CMS in the classical sense). So, I'm pretty much out of ideas; obviously I could just write my own Product from scratch, and that's what I'll be looking into in the meantime, but this seems like something that should be possible, and I hope I'm just missing something or being misled by what I've already read. Please help :) Regards, Jeff - -- Jeffrey E.

Newbie questions:
by Enrique Arizón 11 Apr '05

11 Apr '05

Hi again, I'm starting to make up with Zope, but still basic doubts remains: Q1: When using normal python I'got used to the dir(Object) to learn new APIs/Libraries. But when trainning with my first Zope Scripts I can't. The "dir not defined" error appears. ??? Q2: I can access the Zope management console and the help system but when I got to Zope Help -> API Reference -> "Something" I'm requested for a user/password. I try with the one I defined during the initial setup (the same I use to access the Zope Man.Console) but is rejected. What I did wrong? Thanks in advance for any help, hint, link! ENRIQUE

Description Strings in Archetypes
by S.D. 11 Apr '05

11 Apr '05

I'm running Archetypes 1.3.2-final in Plone 2.0.5 (Mac OS X Server). I added the Article example from ArchExamples to the available items list in a Plone site. It works fine except for the fact that when you look at a list of Articles inside a given folder, each item's Description is taken from the Description string of the containing folder rather than the Description attached to that individual Article. For example, if I create a folder named "Foo" whose Description field reads "Place your foo in this folder," that description is attached to each of the Articles you see when you look at the folder listing. Apparently, the Description info is being taken from the wrong "Description." How can I adjust Archetypes to find and display the correct, Article-specific Description? Thanks! Scott

Newbie ZPsycopgDA question
by Heather Bumbalough 11 Apr '05

11 Apr '05

I am very new to Zope & Python so please forgive me if this is stupid question or if the answer is posted elsewhere (I've looked!)... I am using Zope v. 2.8.0-a1, Python v.2.3, and psycopg-1.1.18. After adding the ZPsycopgDA connection in Zope the Status indicates I am connected to the database but the tables do not show up on the Browse tab and when I attempt to perform a query on the Test tab I get the following (from the log): Traceback (innermost last): Module ZPublisher.Publish, line 113, in publish Module ZPublisher.mapply, line 88, in mapply Module ZPublisher.Publish, line 40, in call_object Module Shared.DC.ZRDB.Connection, line 123, in manage_test Module Shared.DC.ZRDB.Results, line 76, in __init__ TypeError: object does not support item assignment I have tested adding tables and removing them and that works fine, but I have to use phpPgAdmin to see them. Any ideas on what I need to change? Thanks!

Please look at the "Security" tab of one of your documents: I'm willing to bet that, after publication, the "View" permission is granted to the Anonymous role. In that case, the settings on the folder are irrelevant. To make those settings relevant, you are going to have to change something: using a DCWorkflow (there is one available which mimics the 'default_workflow') and tweaking the security settings for the "published" state is your likeliest bet. In that case, you would: 1. Delete the 'default_workflow' from the 'portal_workflow' tool. 2. Create a DCWorkflow in the tool, selecting the option labelled "default_workflow (Web-configurable workflow [Classic])". 3. Change the security settings settngs on the "published" state, turning on the "acquire" flag for the "View" permisison and turning off the grant to "Anonymous". 4. Use the "Update security settings" button on the "Workflows" tab of the workflow tool to re-apply the settings you have just tweaked. I've readded the Zope list to the address; note that, since this is workflow-related, the zope-cmf list would be a more appropriate forum.

how to expand a branch using dtml-tree ?
by BonviciniJ＠keops.net 11 Apr '05

11 Apr '05

I would like to know if its possible to expand a specified branch of a tree,using the dtml-tree tags. I use this tag to display the tree of my site: <dtml-tree expr="Ebullition.pages" nowrap=true single=1 skip_unauthorized> <A HREF="<dtml-var absolute_url>"><dtml-var title_or_id></A> </dtml-tree> But I have a problem.I want the chosen branch to keep expanded when the user click on the link. At the moment, when I click on a branch (expanded or not), the page is called buit the tree is initialised (all branches collapsed) So I wonder if its possible to kepp the branch expanded (by adding a special line, or send via post the id of the branch and expand it on the next loading of the page). I add that The tree is in the same page and I don't want to use frames thanks a lot for your help, and scuse for the english

Anonymous users can download files stored in a restricted folder
by Barbara Harris 11 Apr '05

11 Apr '05

Is it possible to restrict access to the file download function by setting permissions on the folder containing a published file? In a Zope 2.6.4 CMF site, running on Apache, I have removed anonymous access from a portal folder (the restricted folder) and published documents and files in that folder. If a document elsewhere on the site contains a hyper link to a DOCUMENT in the restricted folder, anonymous users are prompted to login to the site when they select the link - this is what I want. However, a hyper link to a FILE published in the restricted folder triggers the Windows file download window and allows an anonymous user to download the file. Without introducing special procedures, I would like to provide the content owner with the facility to publish files in the restricted folder, and create hyperlinks to these files throughout the site that can only be accessed via Zope members. Initially I restricted the folder by deselecting 'Acquire permission settings?' and selecting Manager and Member roles only on the following permissions: - Access contents information - View Subsequently I deselected and reset the roles on all the (restricted folder's) permissions allocated to the Anonymous role at Zope instance and site level, but it made no difference. Tacking 'view' onto the end of the file url works, but this requires additional user intervention and an extra step in the download, so I'd rather find a once-off permissioning solution if I can i.e. http://myCMFsite/myRestrictedFolder (loads the login page - desired result) http://myCMFsite/myRestrictedFolder/myPublishedDocument (loads the login page - desired result) http://myCMFsite/myRestrictedFolder/myPublishedFile (triggers the Windows file download window - not acceptable) http://myCMFsite/myRestrictedFolder/myPublishedFile/view (loads the login page - desired result) The content owners' platform is IE6 or Firefox1 running on Windows 2000 or XP.

Running different Zope versions
by Henk Laloli 11 Apr '05

11 Apr '05

Is it possible to run different Zope versions on one machine? I have a Zope 2.6.4 running and a Zope 2.7.3 both on a Windows 2003 server. They use their own python. I run them on different port numbers configured in the zope.conf file. Both are installed as services. Yet, when both are started usually only the 2.6.4 is available. I have to turn it off to reach the other. What did I forget? Any suggestion appreciated. Henk Laloli
