Zope 2 Development Best Practices
by Edward Pollard 14 Apr '07

14 Apr '07

Greetings, A few years back our institution adopted Zope to support some CMS- like development on a zero-dollar budget. We achieved our primary goals in no time at all, and we very happy. Since that time we have used Zope to deliver a number of solutions to our organization. However, as the complexity of our operation increases, it becomes more and more apparent that our coding standards for Zope are very low. We've leaned on the existing Zope community - adopting code, borrowing ideas, trying to learn - but have never seen anything that helps us better understand the philosophy and structure that would underly a strong understanding of Zopishness. For instance, here are a few gems from our playbook. Please note first that everything works to our needs and we are trying to find a way out of the darkness. We're smart folks, but I fear we have strayed far from the path of wisdom and light. - We have never developed a python based product, although we have hung a gigantic amount of external methods off of a half dozen pages to make it go. And yes, we use ZClasses (shock) - We have solved problems by modifying the ZServer source code. - We have developed entire database driven products inside external methods. - Every Z SQL Method we have has a python script associated with it to massage input and output (and manually enforces security). Of course, a google of Zope Best Practices just brings me a bunch of Plone development stuff. That is of no use. So where is the knowledge I seek to be found? Understanding that open source products are prone to such abuses, I've not been able to find anything as a starting ground to reform our ways. Thanks in advance. -- Edward J. Pollard, B.Sc.

manipulating zodb from independent database connection
by Tim Nash 14 Apr '07

14 Apr '07

Does anybody have a script available that shows how to insert objects into the ZODB root['Application'] from a non-zope process outside the Zope application? Everytime I try to read root['Application'] I get a page template error. I'm using zope 2.5 (matches a book I like) and doing like so: >>> from ZODB import FileStorage, DB >>> storage = FileStorage.FileStorage('Data.fs') >>> db = DB(storage) >>> connection = db.open() >>> root = connection.root() Also, can the ZODB be altered this way on a running Zope instance? I would like to have a script run on cron and insert objects and remove objects from the ZODB while the zope instance application is running. I'd like these newly inserted objects to be Zpublishable as well. Thanks! Tim

Changing links base address
by Peppe Top 13 Apr '07

13 Apr '07

Hi, thanks to your help I've successfully searched and edited the content of the site (the guy who manged it is unavailable at the moment). Now when I look at the html I see there are a lot of absolute links like: <base ... www.site.net <script ... www.site.net <link ... www.site.net...css <href ... www.site.net Because I have to change domain, I was looking to replace those links, with www.newsite.org What's the best way to do that? Would it be a good idea using relative links? I understand that my apache-zope configuration utilizes VirtualHostMonster to translate addresses so I guess absolute links could be there for good reason, right? This is apache+python2.3.5+zope2.8.7+plone2.1.2 Thanks for your time -- Peppe

Please Help - Extracting Info From ZEXP File
by s 13 Apr '07

13 Apr '07

I just took over a website that was done in Zope/Plone. The person formerly responsible for it was not helpful to the client or me in the transition process. Basically he emailed a ZEXP file to me, told me it contains everything I need, and washed his hands of the whole project. I was able to "grab" nearly all the html, css, and javascript files through the web before he removed the site from his server, but now I realize a few pages were missed. So, it seems the only possibility of restoring those missed pages is if 1) everything really is in that ZEXP file and 2) I can find a way to "get to it." I know nothing about Zope/Plone and, no offense to anyone, do not plan on adding it to my repertoire of knowledge in the near future. I just want the "normal" HTML content as it would've been displayed for these certain pages that were not grabbed before he removed the site. Is this possible? If so, could someone please spell out exactly how I can go about retrieving this information from the ZEXP file? Sincerely, Shawn Spinner at networthyinc dot com

nested queries and zpt
by SpiderX 13 Apr '07

13 Apr '07

I have an internal application that I am developing, about server configurations. I have a list of customers who own servers. I have a list of software which is linked to the list of servers. My server list looks like this (simplified): url: "ServerList?CustomerID=123456" <tal:x repeat="server here/serverlist-sql"> <tal:x replace="server/name">servername</tal:x> <tal:x replace="server/ID">server ID number</tal:x> <tal:x replace="structure here/ServerSoftwareList">list of software goes here</tal:x> ...</tal:x> The problem is that the ServerSoftwareList needs the "server/ID" passed to it for the query, which will return the software on file for that server... any ideas? -- Thanks, Derek Wilson

Problem with using versions.
by Catherine E. Reinehr 12 Apr '07

12 Apr '07

Hi, I've been working in a version for over a week and finally finished my changes today. I saved them and quit the version, but the affected folder still has a lock on it. I've tried four times now to save my changes, and it's just not working. The first time, it seemed to publish the changes but the folder was still locked. On later tries, I encounter an error when I try to access the page after saving changes. Any suggestions? Thanks, Cathy ----- Catherine E.

VirtualHostBase VHM keyword doesn't work.
by Mark, Jonathan (Integic) 12 Apr '07

12 Apr '07

Zope 2.9 says in the Virtual Host Monster About Tab: "For example, suppose Zope is running on port 8080 behind an Apache running on port 80. You place a Virtual Host Monster in the Zope root Folder, and use Apache to rewrite "/(.*)" to http://localhost:8080/VirtualHostBase/http/www.buystuff.com:80/buystuff.com…." However, the following in my Apache 2.2 httpd file does not work: <VirtualHost *:80> RewriteEngine on DocumentRoot /var/www Servername goodbyeken.com RewriteRule /(.*) http://goodbyeken.com:8080/VirtualHostBase/http/www.goodbyeken.com:80/goodb… </VirtualHost> The above directive results in a Zope "resource not found" error. I have a Virtual Host Monster called myVHM in my Zope root directory. myVHM is able to do redirections that do not include the VirtualHostBase keyword. Why doesn't the VirtualHostBase keyword work?

Thanks to everyone who helped me set up Zope 2.9 behind Apache 2.2. I copied the rewrite rule that Hara Dilley provided and everything worked: RewriteRule ^/(.*) \ http://localhost:8080/VirtualHostBase/http/%{SERVER_NAME}:80/myVHM/VirtualH… [L,P]
