I keep getting sent to the test input form on my query "NewsGetStory". How can I just get the results back? <dtml-in NewsGetHeads> <A HREF="NewsGetStory?iID=<dtml-var iID>"><dtml-var head></A><br> </dtml-in>

>From: Chris McDonough <chrism(a)digicool.com> >This is strange stuff. Have you checked the Sybase transaction log >lately? When it gets full, Zope doesn't like that too much. (1) How do I check the transaction log? (I am a newbie to Sybase.) (2) I am also getting another error. (I append the error message at the end of this posting.) I went into db.py file and printed out the value of f.datatype is 17 when it crashed. Does this help to trace the source of the bug? What else can I do to trace the bug? After the "invalid buffer element type" error, all hell breaks loose and Zope starts to issue more and more strange error messages.

Is there any custom code around this logic?). BTW, absolute_url did change to support virtual hosting in 2.x. This could be causing a problem in your ZClass constructors. Jason, try inspecting the return value of absolute_url in your constructors, you may have to prepend a / -Michel

add[Folder, DTML Document]
by Bill Scherer 14 Jan '00

14 Jan '00

I've written a simple index_html method that allows me to subvert Zope's folders to create a url directory. the method iterates through objectValues(['Folder', 'DTML Document']). If the object has a property 'url', it displays it as a link, otherwise, it's a folder and is displayed as a link to move into that folder. It's simple and works well. My problem is that I'd like to simplify adding links and folders. For now, I've been using the management interface to do so. I'd like to build my own. I was able to create an addFolder method, and it worked fine except that it returned me to the management view of the folder, instead of the standard public view of the folder. I would like to create an addDTMLDocument method, but I couldn't figure out how to do so while also adding a property (url = "http://xxx.yyy.zzz", etc). Any help is appreciated, and I can upload what I have to my zope.org folder if that would help. Thanks, Bill Scherer

cut & past failing
by Bill Scherer 14 Jan '00

14 Jan '00

I'm using Zope 2.1.2, with zserver on linux, and my cut and paste doesn't work. I can cut/copy something, and when the page reloads, I have a paste button, but when I click it, I get an error saying "no clipboard data found". If instead I navigate to another folder, I have no paste button. Any ideas? Thanks, Bill Scherer

<SELECT> in forms.
by Guy Davis 14 Jan '00

14 Jan '00

There is probably a really simple explanation for this, but I can't figure it out. Any help is appreciated. I am reworking the Search interface for a SQL Query, it works fine using the INPUT tag generated automatically. <input name="priority" width=30 value=""> However if I use the following select tag in place of the plain INPUT, the 'priority' variable is never pushed onto the request and my query method complains that it's missing. <SELECT NAME="priority" SIZE=7> <dtml-in priority_choices> <OPTION><dtml-var sequence-item></OPTION> </dtml-in> </SELECT> In the above statement, 'priority_choices' is a 'lines' property of the containing folder. This gives me the list of priorities, I'm looking for. How do I properly use the SELECT tag to ensure the variable gets put into the REQUEST when the form is submitted? I looked at the Selection List How-To, but this doesn't seem to address this problem. -- Guy Davis mailto:davis@arc.ab.ca (403) 210-5334 Alberta Research Council

Brainstorm: Zope behind proxying cache?
by Jonathan 14 Jan '00

14 Jan '00

Hi, Been brainstorming a little while about modifying HTTP requests combined with a high speed cache in front of a dynamic source of data, such as Zope. Idea: Put a proxying cache with content negotiation, rewriting of requests etc. in front of Zope. First time a page is requested (client requests it from the proxy which knows where to get it because it's configuration files tell it how to handle a request) it is cached. The next request is served directly from the cache. As soon as a page changes it is fetched from Zope and cached again. It would also allow you to use any mix of static and dynamic content, because pages that stay the same are served directly from the cache and Zope is never hit to serve that page. Allows to use Zope as a content management tool too. So what's your view? I know that a request can be modified behind the scenes based on the data the client supplies - request, filetype, language, browser type, IP address etc. It's also possible to cache the files requested, but I am not sure how the cache would communicate with Zope and vice versa. The HTTP protocol offers some hooks to cache a file for a limited time only if I am not mistaken, but the ideal solution in my view would be a button in Zope called 'Publish' which would send a message to the cache resulting in the removal of that particular page... Just brainstorming here :) Anyone with suggestions, comments? Thnx Jonathan -- UR Communications - Solutions for a wired world Who, what & where @ http://www.ur.nl/
