Zope 2.6.1 don't run in Linux Redhat 7.3
by Eduardo Mestre Saez 14 May '03

Hi, I can't run Zope 2.6.x in my Redhat 7.3 server. It simply don't start. I use the source distribution, the binary distribution and a rpm packages. The Redhat runs fine (it has a Oracle database, Samba, a IMAP server... whithout problems), and I installed the correct Python (version 2.1.3). The Zope 2.5.1 runs fine in this system, but I want use Plone and it needs Zope 2.6.1. Thanks! --

Tip: 2.6.1 + exUserFolder + Browser
by Cliff Ford 14 May '03

14 May '03

I ran into a wee problem which took me ages to solve, so I thought I would share it in case you have it too (and don't know) or a better solution. So: I am developing a site and have exUserFolder for authentication purposes. I also have an experimental site for testing developments that are likely to go wrong. The development site is using Zope 2.5.1 and everything works nicely. The experimental site had Zope 2.6.1 installed and it seemd to work nicely too. Except that if the web browser happened to be Netscape 4.7 then the exUserFolder refresh page hung (i.e. no Refresh). Also, if the browser happened to be Internet Explorer 5 then a Server Internal Error 500 was reported. All I could find in the mail archives was a reference to older browsers not implementing Refresh reliably. So why should the same browser work with one site and not the other? I noticed that in 2.5.1 the refresh page has Traceback information as a HTML comment, but that in 2.6.1 the Traceback has been moved to the error log. So putting about 900 hidden characters in the Refresh body makes NN4.7 and IE5 work again. with 2.6.1 For the record, I just added  to the body of Products/exUserFolder/dtml/docLoginRedirect.dtml Cliff _______________________________________________________________ Dr C.E.Ford, Senior Lecturer in Geology Grant Institute of Geology and Geophysics Telephone (+44) 131 650 4838, Fax (+44) 131 650 5738 http://www.glg.ed.ac.uk/people/academic/FordCliff.html

adding additional tabs to the dtml document view zmi
by dean hale 14 May '03

14 May '03

hi Apologies if this is an incorrect list to post this. I'm currently using IE Editor for Zope from http://vsbabu.org/webdev/zopedev/ieeditor.html all works fine, a WYSIWYG tab appears on any *new* dtml document i create (followed the instructions and created a new ZClass derived from DTML Document). However the problem is that we have several hundred existing dtml docs and i cannot figure out how to add the tab to them, rather than creating them anew. Any advice appreiciated. Thanks dean -- Dean Hale Information Services Web Development Manager 0191 515 2424

VS: automatic navigation devices
by Børge Kjeldstad 14 May '03

14 May '03

Hei! I have with zope developed some simple e-learning program which teach users safety and security topics such as fire protection, first aid, environmental policy and so on. It is intended for hotel staff personnel.¨ The program is actually only a large number of web pages with information. As in a book this information is divided into chapters and subchapters. In zope this is done using folders. I have one folder called Fire_protection, one called First_aid and so on. These folders then have their subfolders, and subsubfolders. These folders share some methods like the standard_html_header, standard_html_footer, and a method for generating a table of contents at the first page in each chapter or subchapter. Now, at the bottom of each page, I have some navigation buttons. Depending on where you are in the learning program these are: previous, next, table of contents, first topic and back to start. The buttons are generated using a form action method like this: <td> <form action="<dtml-var first_topic>"> <div class="form-element"> <input class="form-element" type="submit" value="First Topic"> </div> </form> </td> The <dtml-var first_topic> refers to a property with the name first-topic that I manually give to the folder which holds the first topic in this chapter. The value of this property could for instance be fire_protection_11. Consequently, I have manually, and for each folder and subfolder on the entire site, created properties for previous, next, table of contents and first topic. Each time I create some subchapter somewhere in the site, I have to manually change the values of these navigation properties in the neighbor previous and next subchapter. This in order to have their navigation buttons point to my new subchapter. This is not very dynamic. Ideally I should have one navigation method in the rootfolder, that created all the navigation buttons on all the pages of each chapter and subchapter automatically. And if I added or deleted some chapter (folder) somewhere in the site, this navigation method should automatically update my navigation buttons. Do you have any idea of how I could create such a navigation method, or in any other way accomplish this? Best wishes and kind regards Børge Kjeldstad

RE: [Zope] GET vs. POST

The Web Way is to submit information to the server (especially data that might change the state of the server or its data) using POST, otherwise to retrieve information with GET. There is nothing to stop you from using a POST for submitting length form data if you want to. Sounds like there is some crucial bit of information you have not told us. Cheers, Tom P

Going Back
by Greg & Janet LINDSTROM 14 May '03

14 May '03

What, if any, resources are available in Zope (2.6) for me to use to construct "back" buttons/links. Is the page I came from stored anywhere, or can I access it? Is there such a beast as a "back" input type (similar to "submit" or "reset")? If not, how can I set up a "back" button/link? Thanks for your help, --greg
