Hello. I have a standard_html_header defined in the root folder that looks like this: <dtml-var header.html> So the actual header is keps in header.html which is also in the root. header.html has <dtml-var sidebar> in it. I defined sidebar in the root and override it in sub-folders but it sitll picks up the sidebar defined in the root. This didn't start happened until I did the above trick with standard_html_header and header.html. Any suggestions? I need the header file to have a .html extension so someone can edit them with dreamweaver. Is there an easier way to globally change the name of standard_html_header? Thanks, ^Roman

DTML Syntax contd.
by Oliver Frommel 12 Nov '99

Hello, I am trying to reference an object within the following hierarchy: ..../links/19991108205246/amethod amethod: <dtml-with links> <dtml-with _['19991108205246']> <dtml-var title> </dtml-with> </dtml-with> I have tried several permutations on the "19991108205246" thing without success .. could anyone explain the semantics of the various DTML constructs like .. foo _[foo] "_[foo]" "_['foo']" I think I read through most of the docs but there is no extensive description of the exact syntax (not even in the DTML ref).. Please correct me if I am wrong .. thanks Oliver

ZLDAP 1.0b1
by Jeffrey P Shell 12 Nov '99

12 Nov '99

The ZopeLDAP Product consists of two actual products in the same release: ZLDAPConnection for managing connections to LDAP Servers and returning Zope-ish Entry objects, and ZLDAP Filter Methods for querying LDAP Servers. You can see a model of it online. UserLDAP is similar to UserDb. It reads authentication information out of an LDAP Server and has customizable ZLDAP Filter Methods for looking up users. Adding/Editing/Deleting of users is not in this release. UserLDAP can make use of SHA1 and CRYPT encoded passwords. ------------------------------------------------------------------------ ZopeLDAP requires David Leonard's ldapmodule, from http://www.it.uq.edu.au/personal/leonard/dc-prj/ldapmodule/ and the compiled module needs to be (naturally) in your PYTHONPATH (or in ZLDAPConnection/). ------------------------------------------------------------------------ http://www.zope.org/Members/jshell/ZopeLDAP/ This is a still-early beta with little documentation. The API, especially as shown in the model, *should* remain frozen at this point. All known issues (and there are some) are in the README.txt file in the release. -- Jeffrey P Shell, jeffrey(a)Digicool.com http://www.zope.org/

Risky Giving Anon User Permission to View Management Panel
by Jeff Rush 12 Nov '99

12 Nov '99

Are there any security risks associated with giving the anonymous user under Zope the 'view management panel' permission? He doesn't seem to be able to delete/modify/add things, and I thought it might be good on some sites intended for demo to allow people to peek under the covers and see how it was all done. Zope.org seems to give you this permission to some degree, since you need it to be allowed to click on the "view DTML source", but they (somehow) prevent you from getting to the actual '/manage' interface (I'd love to know how). Besides protecting code-under-development, in their case, is there any risk I would be taking? I don't hide passwords or mention confidential things in my DTML... ;-) -Jeff Rush

Acquisition problem
by Tim Haines 12 Nov '99

12 Nov '99

Hi there, I'm having a problem with acquisition. This may have been covered before, but searching through the 2000 messages I have, I didn't find it. My problem basically involves the acquisition process not traversing the namespace all the way up once it has found a "semi-match". For example: I have the follow folder structure: / index_html show_images /images bob <image object> henry <image object> /subfolderhenry index_html /images henry <image object> My /index_html uses show_images to display /images/bob and /images/henry I want my /subfolderhenry/index_html to use show_images to show /images/bob and /subfolderhenry/images/henry. When /subfolderhenry/index_html is rendered, the acquisition method goes looking for <dtml-var images/bob>. What seems to be happening is that it looks in /subfolderhenry/images and doesn't find bob. The problem is that it returns an error instead of moving up the tree to look in /images (where it would find bob). Am I mis-understanding the way acquisition should work, or is this a problem? As a work-around I can drop the images directories, and host the images in the actual directories. Not a great solution though. I look forward to your reply. Please reply to mailto:tim_haines@hotmail.com aswell as to the list Tim.

List of Folders
by Ulrich Wisser 12 Nov '99

12 Nov '99

Hello, recently I read a thread here about viwing the subfolders of a folder. Thats excatly what I want to do, but it doesn't work. I have two problems: My folder structure is eCHECK Admin Manage Kunden luna <- has property kunde sub1 sub1.1 sub2 puna <- has property kunde subA subB subC I want to view a menu with "Admin, Manage and Kunden" in my navigationbar. I did the follwing code: <dtml-with eCHECK> "menutitle"--></A> <dtml-in "eCHECK.objectValues(['Folder'])"> <dtml-let item=sequence-item> <dtml-if "AUTHENTICATED_USER.has_permission('View', item)"> <BR><A HREF="<dtml-var absolute_url>"></A> </dtml-if> </dtml-let> </dtml-in> </dtml-with> When I log in as superuser it works, but when I log in as normal user with a local role authentication fails, although the user has ALL ( nd i mean all) permissions on eCHECK, Admin, Manage and Kunden. Further down in the navigationbar I want to display the folders in Kunden.<kunden-name>. I test for the property "kunde" which indicates I am viewing something under Kunden.<kunden-name>. Even when I am in sub1.1 I want the menu to read "sub1,sub2". My code to this: <dtml-if "_.has_key('kunde')"> <dtml-let userfolder="'Kunden.' + kunde"> <dtml-with "userfolder"> <TR><TD> <dtml-in "objectValues(['Folder'])"> <dtml-let item=sequence-item> <BR><A HREF="<dtml-var absolute_url>"></A> </dtml-let> </dtml-in> <BR><A HREF="/">Logout</A> </TD></TR> </dtml-with> </dtml-let> </dtml-if> This doesn't display any folder at all. I tried <dtml-with "_.namespace(userfolder)"> which leads to "Kunden.luna not found". Any suggestions?
