[ANN] zshell: The Zope Shell
by Jerome Alet 04 May '01

04 May '01

Hi there, I'm pleased to announce you the Zope Shell version 0.001. The Zope shell is a GPLed Python Script which makes some of the most commonly used unix shell commands available from within Zope, to manage the ZODB contents. You'll find this 155 lines script attached to this message. As for the 0.001 version which is attached to this message, the following commands are recognized: cd, cp, mv, rm, ls there are some restrictions however, and it doesn't seem to work with absolute paths, read the source for details and the future commands. zshell accepts an unlimited number of commands to launch in a single Zope transaction, so feel free to combine these five commands to do some very complicated stuff. Despite its current limitations it works fine here on Zope 2.3.2+Hotfix0501. Please feel free to send me any comment about this software. Such similar functionnality included in Zope's core would make me VERY happy. hoping this helps.

Upgrade path from 2.2.2 and PTK
by Paul Winkler 04 May '01

04 May '01

Hi, OK, I have a site I've been working on for months that's based on Zope 2.2.2 and PTK 0.8.2. That's what was current when I got started. Now I want to update things a bit before I put this on a production server. My site is a heavily-customized version of the DemoPortal from PTK 0.8.2. Well, now you guys are up to Zope 2.3.2 and CMF 1.0. Can anyone recommend the safest, least painful procedure for upgrading my stuff? Once I get Zope upgraded, can I just install CMF alongside PTK and migrate things over piecemeal? (I'll probably have to do it a bit at a time, as I've customized quite a lot of PTK...) -- ................... paul winkler .................... custom calendars & printing: http://www.calendargalaxy.com A member of ARMS: http://www.reacharms.com home page: http://www.slinkp.com

>From you original mail I think you've just pulled the DocumentTemplate module from Zope, and are using it in your own Python CGI.

#include with DocumentTemplate?
by Lance E Sloan 04 May '01

04 May '01

I'm fairly new to Python and when I asked this question on a couple of the python.org mailing lists, I was told I should probably ask here instead. I'm writing some CGIs in Python and I borrowed the DocumentTemplate module from Zope because it does most of what I need. However, there's one thing that it apparently doesn't do that I would really like. And that would be to use "#include" tags to read in other DTML documents and parse them. That is, tags like this:  Does DocumentTemplate already handle that? I couldn't find it in the documentation. If it's not already built-in, is it possible to add such a tag? I've seen the examples on zope.org for adding tags to DocumentTemplate's parser, but I don't know if its possible to get it to read a new file and parse it in the middle of parsing another template. Has anybody already implemented this? Thanks in advance. -- Lance E Sloan Web Services, Univ. of Michigan: Full-service Web and database design, development, and hosting.

loginmanager NameError
by Erik Myllymaki 03 May '01

03 May '01

I am following the HOWTO at: http://www.zope.org/Members/jok/SQL_based_LoginManager I think I have done everything as directed, but I get a name error when trying to access the folder with the new LoginManager inside for the first time. I have written a teststub to check which method causes the error and it turns out they all do - they can't find the zSQL methods even though they are in the same folder: Error type: NameError Error Value: SQL_check_user Any advice appreciated.

Re: [Zope] Re: Product Creation and Permission
by Jason Joy 03 May '01

03 May '01

I dropped the __ac_permissions__ as well as made some changes per your recommendations and got a fundamental change. Thanks for your input into this. Other things are going on, however, that I don't quite understand: To set up a small example of what I am doing, I am making a Object in Zope called "Fish" that is an instance of A. In the SQL database that is indexed with Fish is Red Snapper, Trout, and Haddock. So, by clicking on Fish I get a management screen that shows each one of these fish. Instead of getting another management screen when I select a specific fish, I get the index_html of the folder. All the links in the Fish folder go to: ../Inventory/Fish/Trout/manage_workspace, so that part is okay... It's just not going to another management screen. Interestingly, _getOb in A is called twice during this whole procedure.

Complex dtml-in/ZopeFind ?
by Kai Hofmann 03 May '01

03 May '01

Hi, I have the following code now: <dtml-in "subdir.objectValues('DTML Document')" sort=bobobase_modification_time reverse> <dtml-if sequence-start> <tr><th>bla</th></tr> <tr><td> </dtml-if> <dtml-if "(startdate <= _.DateTime()) & (_.DateTime() <= enddate)"> <h2><dtml-var title></h2> <dtml-var sequence-item> </dtml-if> <dtml-if sequence-end> </td></tr> </dtml-if> </dtml-in> the problem here is that the sequence-start/end will always be executed - for the case that there is an object outside of the start/end date window! So I have to move the if (startdate <= _.DateTime()) & (_.DateTime() <= enddate) condition into the dtml-in .... Or replace thedtml-in with ZopeFind or something else .... Is it possible to but everything I need into a dtml-in or a ZopeFind? As it looks to me - I can not add the if condition to the dtml-in - on the other hand I don't see how to sort the result of an ZopeFind ... But hopefully I am still a little blind and someone can help - Thanks Kai -- Institut für Seeverkehrswirtschaft und Logistik http://www.isl.org/ Dipl.-Inform.

SiteAccess and broken manage links
by Jason Cunliffe 03 May '01

03 May '01

Hello Zope2.3.2 Apache1.3 on Redhat6.2 SiteAccess ProxyPass combo as described by 'anser' in famous How-to http://www.zope.org/Members/anser/apache_zserver Zope is reached at http://www.mysite.com/zope Apache Directive looks like this: ServerName http://www.mysite.com ProxyPass /zope http://www.mysite.com:8888/ ProxyPassReverse /zope http://www.mysite.com:8888/ ProxyPass /misc_ http://www.mysite.com:8888/misc_ ProxyPass /p_ http://www.mysite.com:8888/p_ Ok so everything* is working fine _except_ the breadcrumb links into top of the main big Zope management window. All links from there are always missing /zope after the domain and before whatever method or object they call. Tabs work, trees work.. *[but one product 'JavaTelnetSSH' has a broken icon also. works well but looks messy&puts clients off] Q: What can I add to make this work coreectly? Is this a job for SiteAccessRule. I played with it.. fascinating dangerous stuff. How to write a rule which knows it is being called from that part of the management window and can insert a /zope? Or is there a simpler solutino use ProxyPass? Is this a b u g? Thanks - Jason ___________________________________________________________ Jason CUNLIFFE = NOMADICS['Interactive Art and Technology']
