Catalog wierdness?

Using: Zope Version (Zope 2.5.1 (source release, python 2.1, linux2), python 2.1.3, linux2) Python Version 2.1.3 (#1, Apr 22 2002, 16:16:34) [GCC 2.96 20000731 (Red Hat Linux 7.1 2.96-85)] In the catalog, I have a FieldIndex that contains an integer. I want to select all objects where that number is 0 or less. objs=Catalog(number_times_sent=0 ,number_times_sent_usage='range:max' ) However, this returns all items, regardless of the value of number_times_sent. If an object has number_times_sent to 2, and I do this call: objs= Catalog(number_times_sent=1 ,number_times_sent_usage='range:max' ) It works as expected, and that object isn't returned. Also, when number_times_sent is 0, the following does work. objs= Catalog(number_times_sent=0) Since I won't have a negative value, this does what I want. However, number_times_sent is variable, so it would be nice if 'range:max' worked for zero. Is there any logical explanation? Bug? Am I doing something wrong? Thanks, Mark

Commendation in order for EasySite
by Jeffrey Franks 17 Mar '03

17 Mar '03

Hi fellow Zopists, I've been playing around with Zope for a while now and have been road blocked on the actual use of ZPT's, Python scripts, etc. for creating a well structured web site. What I really needed was a simple example, which I did not find until the EasySite announcement was made on the Zope.org web site. If you are less experienced like me, yet would like to apply Zope for a live web site, then I would recommend EasySite as a light weight framework for using Zope. http://www.zope.org/Members/beno/HowTo/EasySite I would like to say that my experience with EasySite has been very positive. I've learned more about Zope and how to use it more from EasySite than reading Zope Bible, all the Zope manuals, etc. My experience has been successful in my opinion because of the following: * EasySite has been boiled down to just the essentials for good design, and easy comprehension * It is extensible without jacking with the foundation * It is easy to incorporate content from 3rd parties and other tools * It begs for the less experienced Zope developer to get their feet wet, think a lot, be involved in a very positive experience, and enjoy what they are doing. Thank you for the opportunity to use EasySite. This is a great asset to the Zope community in my opinion! I plan on using it for some commercial websites. -- Jeffrey L.

I have a document in the CMF that has been published but I cannot use search to find it unless I am logged in. Anonymous users should be able to see that file.

Wrong url on absolute_url or portal_url
by Michael Havard 17 Mar '03

17 Mar '03

having a problem getting the absolute_url or portal_url within a CMF site. We have a framed site that puts a ZOPE CMF site in one frame when needed. When the frame is first loaded all the links point to "mysite:8200" instead of where the ZOPE instance is being run "mysite:8300". If I right click on the zope frame and reload I get the correct links but loading it from another frame breaks the link reference. Is there another way to get the url? _________________________________________________________________ Tired of spam?

Macro question
by pskipworth＠touchcorp.com 17 Mar '03

17 Mar '03

Hi, I'm setting up a site that has a different Zope folder per section of content. Each section has multiple pages but each page has a common menu down the left hand side of the page. I figured I would have one main template at the top level, and then a 'sub-template' within each folder that fills a 'menu' slot within the main template. The subtemplate will have a 'content' slot which each individual page will fill with content. However, I tried setting this up, assuming the 'sub-template' would need to be defined as a macro, as well as use-templating the main template. Zope complains, however, that a page can't be both of these things! Any ideas on how to do this 'properly' ?

Newbie: Exception Handling questions
by Luis Mariano Luporini 17 Mar '03

17 Mar '03

Hi list: I'm trying to learn more about Zope/Python. I think it's a really great tool. Now my situation: I'm using Zope 2.6.1 w/ Python 2.1.3, z/psycopg 1.1.2 and Postgres 7.3 on Gentoo Linux. I have a connection open to the pg server, I can select/delete/insert/update without problems. I have now a ZSql method that performs an insert and I have a Python Script that calls it. I'd like to check if the execution of the insert operation was succesful and if not, the reason. Now the questions: 1) I've read about try/except and StandarError. if I use something like: try: some statement except StandardError, e: print e I got a whole string containing the sql executed an a description of the error. So what is e really? Can I get an error number, description and more information out of e? If not how can i do it? 2) Trying to specialize the exception treated I changed StandardError for IntegrityError/DatabaseError but in both cases i got: *Error Type: NameError* * Error Value: global name 'DatabaseError/IntegrityError' is not defined* Then i added to the script "import psycopg", with the same results and finally tried "import psycopg.Error" and got *Error Type: ImportError* * Error Value: import of "psycopg.Error" is unauthorized So which way I have to go?
