It seems like dtml-with is unable to find my images > folder?? I tried to reproduce your problem (Zope CVS) but was unable. Everything works as expected. Are you sure that "Foo_dtml" is a DTML Document (and not a DTML Method)? If it would be a DTML Method, then it might find an "images" in "Subfolder" which does not contain your image. Dieter

You may try to add: 127.0.0.1 localhost to your "/etc/hosts" file. Dieter

The basic Zope security machinery does not associate semantics with the permissions. It is up to the developer (and his sense for consistency and semantics) to choose properly named permissions.

Never use "objectValues" for objects that are not ObjectManagers. They define a stupid and unusable "objectValues" method. If your folder has a property called "User", then you would use: <dtml-if expr="AUTHENTICATED_USER.getUserName()=User"> If your "User" would not be a single user, but a list of users, the following would look promissing: <dtml-if expr="AUTHENTICATED_USER.getUserName() in User"> Good reading for people starting to learn Zope: the Zope Book (-> zope.org) and URL:http://www.dieter.handshake.de/pyprojects/zope/book/chap3.html Dieter

Re: [Zope] need help on mail attachment using dtml
by Dieter Maurer 18 Apr '01

Kam Nejad writes: > ... Mime attachment problem ... > <dtml-boundary type="application/octet-stream" > filename="REQUEST['elvis'].getId() encode=base64>... You forgot a '"' and "filename" does not accept an expression but only a literal, use "filename_expr" instead. Furthermore, though not impossible, it is unlikely that "REQUEST['elvis']" contains an object with a "getId" method. Let's assume it is a file object you just downloaded. Thus: <dtml-boundary type="application/octet-stream" filename_expr="elvis.filename" encode=base64 ><dtml-var "elvis.read()" ></dtml-mime> </dtml-sendmail> may work. Dieter

calling dtml-var from ZwikiPage; strange syntax
by John Hunter 18 Apr '01

18 Apr '01

If I have a Script (Python) python object with id HelloWorld in a ZWiki web which has just one line: return "Hello World" and then insert: <dtml-var HelloWorld> in one of my ZWikiPage's, the output when I view the ZWikiPage is Hello World> ^ unexpected angle bracket in ZWikiPage output If I change the ZWikiPage to just be <dtml-var HelloWorld ^ no closing angle bracket The 'Hello World' output is displayed with no improper angle bracket when I view the ZWikiPage. Is this a parser error or a feature. Thanks, John Hunter zope 2.3.0 python 1.5.2

This isn't very zope-specific, but Pointing the dns to your firewall's external ip + port forwarding should do it, I once had a similar setup (modulo dns and firewall, but the port forwarding part). Also a siteroot to rewrite zope's generated uris. While being offtopic for this list: You're really running a dns-service on your firewall, accessible from outside? cheers, oliver
