ZODBC hangs up Zope
by albert boulanger 25 Apr '01

25 Apr '01

I am using the ZODBC product in Zope 2.2.4 to connect to an Oracle data warehouse and it seems that all of Zope hangs up when there are tables being locked during updates and a sql query is done using ZODBC. I am using the ZDGchart product to summarize some data in the warehouse. It looks like the ORA-04020 error (Deadlock detected) is not being trapped and then ZODBC hangs up the rest of Zope. Should I be using some other DA product? Thanks, Albert Boulanger aboulanger(a)vpatch.com

RE: [Zope] asp request and response objects
by David Kovach 25 Apr '01

25 Apr '01

That is a good solution with the hidden frame - again, I think the Zope management tool is useful and it works and I know alot of the same functionality could be duplicated in a different (or similar to the edit tool you provide your users) gui implementation - what would be great is integration within HTML/XML editors. Arent there movements going on here with GoLive and Dreamweaver? On the other ASP note - what ASP concepts do you think would be the top 5 that would need to be depicted under the Zope Way? I think: 1. Form submission and Form Response via ASP 2. Dynamic content (like time and date - something simple) placed in a page 3. SQL connection object and subsequent SQL call 4. Page Redirection and passing of form field or hidden data (state) 5. Reading in attributes from an offline configuration page (asp page) to set the values of an online page - like bgcolor,etc. Probably many of these are done a different way altogether and some of which arent the preferred way to do things with ZOPE (like even using a SQL db). But, idea is to look at ASP concepts - describe em in Zope terms. and show how they can be accomplished more effectively and efficiently with ZOPE.

more dtml-in and content negotiation
by Kai Hofmann 25 Apr '01

25 Apr '01

Its me again, asking stupid questions I havent found answers within the docs :( Is it possible to extend the <dtml-in "sub.objectValues()"> <h2><dtml-var title></h2> <dtml-var sequence-item> </dtml-in> code a little, so that will only display objects ending in "_de" or "_en" ? Is there a kind of "content-negotiation" like I use it with Apache and plain html files: index.html.de index.html.en and apache picks out the correct one depending on the users browser prefs - is that possible with zope too?

How to call image metadata using LocalFS?
by Ausum 25 Apr '01

25 Apr '01

When iterating over image files within a LocalFS folder, I'd like to expose their width and height sizes. Although LocalFS file objects can't store user-defined metadata for the time being, it's possible to see an image's width and height values at its properties tab. I've read the how to on "Using DTML With Local File System Objects" but I couldn't find the solution there. Is it possible to call the width and height values of an image item, from a LocalFs iterate procedure? Thanks in advance, Ausum

mysterious problem
by sharlynn 25 Apr '01

25 Apr '01

I am using a Winbook Si notebook computer, with IE 5.5, and zope 2.3.0. My computer runs zope, recognizes my hostname, and port #... but will not allow me to access the Management Interface with the passwords i have CAREFULLY entered in zope set up/installation. I have reinstalled zope several times, have changed my IP address, have purchased a network card...all to no avail. I have had this exact problem every single time i have tried to access the management interface, regardless of the problem solving done. If you have any ideas, suggestions, brainstorms...I would greatly appreciate it. The following text is the error message I receive after unsuccessfully entering my user name and password at the management interface prompt. Zope Error Zope has encountered an error while publishing this resource. Unauthorized You are not authorized to access this resource. Username and password are not correct.

Iterative Insertion via the dtml-in tag
by David Elfstrom 25 Apr '01

25 Apr '01

Hello, I've been working my way through the tutorial and documentation, and I found the section on "Iterative Insertion, the dtml-in tag" to be very eye-opening: http://www.zope.org/Documentation/Guides/DTML-HTML/DTML.7.html It's been my first eye-opener to the real power of Zope. Now, when I go to the root of the above document, apparently this information has been depreciated. My questions: 1) where is a newer version of this same example page? The newer docs don't seem to cover the dtml-in tag with such a great example, to such depth. 2) is there a single .html file for the above depreciated documentation, so I can print it out easily? Thanks muchly! David
