Does anyone know how to modify the default index_html? Do I need to do it from the source? Thanks in advance, Ron

Bothered by batches
by Nolan Darilek 25 Mar '01

25 Mar '01

I've recently begun trying to figure out how batches work, but what appears simple is instead causing massive problems, and I really don't know what's wrong. I have the following snippets of DTML in an index_html: <dtml-unless first> <dtml-call "REQUEST.set('first', 0)"> </dtml-unless> <dtml-unless batchsize> <dtml-call "REQUEST.set('batchsize', 2)"> </dtml-unless> . . . <dtml-in "jobs.objectValues()" size=batchsize start=first> . . . </dtml-in> Then I have a BatchAdjustForm method which isn't a form anymore due to recent changes, but it looks somewhat like this (note that the text entry field will probably be nuked soon): <table> <tr> <td> <div align="left"> <dtml-if previous-sequence> <a href="<dtml-var URL><dtml-var sequence-query>first=<dtml-var previous-sequence-start-number>&batchsize=<dtml-var batchsize>"><[Previous]</a> <dtml-else> <[Previous] </dtml-if> </td> <td> First:  <input type="text" name="first"> </td> <td> Size:  <select name="batchsize:int"> <option value="5">5</option> <option value="10">10</option> <option value="50">50</option> <option value="100">100</option> </select> </td> <td> <div align="right"> <dtml-if next-sequence> It worked! <dtml-else> [Next]> </dtml-if> </td> </tr> </table> First of all, you'll probably notice that the batchsize is set insanely small. This app is basically a job board, and is meant to iterate through a list of jobs and extract batches. Until recently I had never tested the batch functionality, but yesterday I added 6 jobs to the board and, despite having set the batchsize to 5, all 6 showed. Dropping the batchsize to 4 has the same effect, but 3 or lower works as expected; I'll see 3 items, 2, etc. Maybe I don't understand how size= works? Also, the BatchAdjustForm simply doesn't work. I consulted the batch example in the Zope Book, and borrowed quite a bit from it, but nothing seems to work. As you can probably see, I tried to simplify the 'next' navigation link to print 'It worked!' and avoid using the code I used for the 'previous' link, but this doesn't seem to ever appear, despite the fact that I'm only displaying a few of the 6 jobs currently in my sample database. Any ideas? This isn't a major problem, but it's one of the last which I'm experiencing with this project and it really annoys me that I can't even get a simple batch query to work. :)

Re: [Zope] Modifying Default index_html

> > So what am I missing? Why don't more people use ZClasses? > > -- I think because Zope is still "foreign" in the sense that, while it works like standard html, it really isn't. I'm still having tons of trouble getting away from the procedural aspects of html/php/general programming when dealing with Zope. It has procedural elements, but so much of Zope is Object Oriented...besides, when dealing with the issue here at hand, you would think it would "easy" to make a simple change like this. With standard html, you can. Maybe because html and such isn't an environment, whereas, that's exactly what Zope is. I would expect changing index_html to be the equivalent of moving a piece of paper, rather than moving a chair, or a couch.

AW: [Zope] can't install PoPy -->now Zope don't find PoPy

First, Sorry for disturbing you again and thanks AdeL and the others, With the python and postgres-dev installed I got build the PoPy-Module. But where is Zope searching for it? I still get the error message ******************************************************************** 2001-03-25T11:56:38 ERROR(200) Zope Couldn't import Products.ZPoPyDA Traceback (innermost last): File /home/zope/lib/python/OFS/Application.py, line 530, in import_products (Object: string) File /home/zope/lib/python/Products/ZPoPyDA/__init__.py, line 34, in ?

Re: [Zope] Zope based Authentication.
by Mohan Baro 25 Mar '01

25 Mar '01

Thanks Tony and Dieter for replying. Zope is a great product. ZPatterns and LoginManager are great products too. I use ZPatterns and LoginManager. Thanks to http://www.zope.org/Members/BwanaZulia/zpatterns_install and other links Basic applicatiuon development require a lot of knowledge to setup. This will deter people from switching to zope from other platforms(for instance from PHP to zope). They also have access to free products and plugins from their user community. In order to develop PHP applications newbies just have to learn PHP programming. In Zope we have to learn Zope + Python + DTML + external methods to fully appriciate an application like ZPatterns and LoginManager. In oder to show that Zope means business when come to solid application development, certain thing must be built-in into Zope. One of them is form based login/logout system instead of HTTP authentication. I am new to zope but you have to understand that a lot of people are new to zope (and have a steep learning curve). Hope more people reply. Thank you. Mohan.

connect to mssql with sybaseda on zope on NT?
by J�lio Dinis Silva 25 Mar '01

25 Mar '01

Hi, I have sybaseda installed on zope on NT. Now I want to connect to mssql :-) I create a sybase connection and enter user, password and server info but I get an Invalid Connection String. Has anyone successfully connect to mssql with sybaseda on NT? If yes, what could I be missing here? Maybe define a sybase data source somewhere on my sybase home poiting to my mssql server? My knowledge of sybase configuration files is limited so can anyone help me here? Maybe someone who made this on Linux knows where to define the data source. Thanx, Julio Dinis Silva _________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com.

Are Versions Reliable?
by Edmund Goppelt 25 Mar '01

25 Mar '01

I'm worried that Versions are not working properly on my Zope 2.3.0 web site. I'm trying to figure out whether I should continue to use versioning and/or whether I have a corrupt ZODB. What has been your experience with Versions? Is this a reliable feature of Zope? Have you ever been unable to roll back changes made in a Version or been unable to commit a Version's changes? Here's what happened: I recently committed a Version to the ZODB, but Zope showed many of the objects as still having uncommitted changes (the red diamond). Further, Zope showed many items as having changed that I know for a fact I did not edit (mainly Python scripts). Worst of all, the site became inaccessible to users, with Zope responding to page requests with a VersionLockError. Thankfully, Zope committed the changes after I saved the Version changes a second time, but the fact that Zope got confused about what had changed and what had not worries me a good deal. I don't understand why users were getting a VersionLockError--isn't the point of Versions that you can try out changes without adversely affecting your users? What is the best way to safeguard my data and web site, in your opinion? What would cause Versions to fail in this manner? Would packing the database help? -- Ed Goppelt
