ANN: ZSybaseDA 1.0.1
by Michel Pelletier 03 Aug '99

03 Aug '99

Greetings, Here is the official ZSybaseDA. Currently, the ZSybaseDA is a level 2 DA, meaning that it will work with a threaded Zope, but all transactions with all other level 2 DAs are serialized in the transaction manager. The ZSybaseDA REQUIRES Zope 2.0! There are several bug fixes in this DA over the previous one (which we didn't ever release so it doesn't matter much anyway...) A bug in the ctsybasemodule that caused open sybase connections to hang around until the process died is fixed A bug that didn't let you re-open a manually close database connection is fixed. And others. Note that the ctsybase module appears to be orphaned by it's original maintainer, as our attempts to get ahold of him have failed. We will continue to extend and maintain his work by taking over the ctsybase code until he steps back up or someone else does. Any bug reports or problems with the ctsybase module should be sent to zope-dev(a)zope.org. Note that although ZSybaseDA *is* an officially supported Digital Creations product, *the ctsybase module is **not** supported*. It behooves us to fix bugs in it, but we cannot prioritize it unless a customer opens a ticket with us. Thanks. Please consider the 1.0.1 release of the ZSybaseDA as tested beta code. There may be another maintenance release in the near future. The ZSybaseDA can be found on the Zope site: http://www.zope.org/Download/ZSybaseDA/ -Michel

Creating a New Object Type - Use ZClass or Python?
by eric jones 03 Aug '99

03 Aug '99

Hello, Forgive me if this is a double post - I sent it to zope(a)egroups.com , and it never appeared in the posts as far as I could tell. I'm pretty comfortable with Python, but new to Zope. We're trying to figure out the best way to set up an academic web site that has a list of publications on it. Each publication has several authors, a description, etc. It will also have a pdf and perhaps a postcript copy of the article. We need to be able to search the author list. I'd like to create a PubClass that, when it displays itself looks like: "Some silly paper" IEEE Trans. on Antennas and Propagation Description: Some rubbish about how great the silly paper is. Authors: Eric Jones, Larry Carin, William Joines PDF: link_to_pdf_file_object (size) PS: link_to_ps_file_object (size) I'd like the Add form to have places for adding all the basic properties. The paper title, journal name, and description are pretty straight forward I think. The authors are a little more troubling. I'd like to make them a list of tuples: [ (first_name,last_name), (first_name,last_name),...] to facilitate searching for a particular author (so that only Larry Carin's papers are displayed on his page). Is there a way to do this sort of thing with ZClasses? Also, I want the Add form to have places to browse for the pdf and ps files - much like a Zope File object - and then add these files to the PubClass object. Is this best done by creating a class in python or with the ZClass interface? thanks, eric

Zope and Editors
by Stephan Richter 03 Aug '99

03 Aug '99

hello everyone, i got finally around to install zope on my machine. Since I am a big PYTHON fan, I was very curious about Zope. And I have to say: IT ROCKS! I got a query and test page up in ~45 min, using the experimental PyGres DB interface. But here my question: I do not want to use a HTML textarea to edit my code. I prefer to use emacs. How do you use external editors with Zope? Do you import files all the time? Or do you copy and paste? Both of these solutions are not desirable, since I check my code every few minutes. I would spend more time uploading to the system. I hope you guys can give me an answer. thank you, stephan -- Stephan Richter iXL - Software Designer and Engineer

Is 'addPostingForm' a Zope object (DTML Document / Method) or a Python method? If it is a Python method, then I can probably explain what's going on - otherwise I'm not so sure, since I can't make a DTML Document or Method behave like this on my b1 installation :( Brian Lloyd brian(a)digicool.com Software Engineer 540.371.6909 Digital Creations http://www.digicool.com

wrong value for integer variable?
by Donald Holten 03 Aug '99

03 Aug '99

I have the followin in my html page:  <!dtml-call "manage_changeProperty(numtemp = numtemp + 1)">  numtemp is an integer property of the html page. When trying to run the ZSQL Method update_AccessCounter(), I get an error saying "Invalid integer value for numtemp". Here is update_AccessCounter(): update WRTable set numruns =  The possible cause for this that I can see is GetRuns() is not returning an integer value. If so, how can I force it to? GetRuns currently is: select numruns from WRTable And numruns is declared an integer in WRTable. If I am wrong, and GetRuns is sending back an integer, what is causing this error? Thanks! Donner

Re: [Zope] Something funny about SQL like?
by Donald Holten 03 Aug '99

03 Aug '99

Well, I've tried escaping the '%', single quotes instead of double quotes, sqlvar instead of var, and none of those have worked. Here's the code again: select * from Users where  like "%%" order by  And here's the error again: Error, exceptions.SyntaxError: unexpected token sequence.near :: 'where firstname'*' like "%Donald%' ******************************* current state = 45 expects: ',', 'UNION', 'FLOAT', 'GROUP', 'VARCHAR', 'DESC', 'SELECT', 'ORDER', 'WHERE', 'AS', 'IN', 'INTERSECT', 'ASC', '*', '+', '(', ')', '.', '/', 'EXCEPT', '-', 'AND', 'FROM', '*', ';', 'INTEGER', 'NOT', '>', 'OR', '=', 'BETWEEN', 'HAVING', '<', 'VALUES', ('nomatch1',) current token = ((-8, 'user_defined_name'), 'LIKE') SQL used: select * from Users where firstname like "%Donald%" order by firstname Like I said, it looks to me like the SQL it's trying to use is fine. Does GadflySQL not support the "like" keyword? Donner

Hi! I was wondering if there was a way to alter the command:  to make numruns an integer instead of a string. Thanks! Donner
