non-External Methods
by Oleg Broytmann 11 Mar '99

11 Mar '99

Hello! In ExternalMethods.html I found: "ernal Methods operate just like normal methods". But what are "normal" methods? The only thing I know is DTML Scripts. Are there other? Could I put Python code into Object Database? Should I? Oleg. ---- Oleg Broytmann National Research Surgery Centre http://sun.med.ru/~phd/ Programmers don't die, they just GOSUB without RETURN.

pretty printable pages at zope.org

We now have sortof-pretty printable pages at Zope.org :). At the bottom of every page with the standard header/footer is a link "Printable Page" which links to the same page being viewed, but passes a value to standard_html_header/footer that is used to _not_ render the surround Zope layout (sidebar, navigation bar). For example, http://www.zope.org/Information/Zen/HTMLMethods?pp=1 .jPS | jeffrey(a)digicool.com zope, through the web. www.zope.org

This would > imply Python code can indeed be part of the Object database, right? Pressing the 'edit' button "reloads" that particular External Method code into the system. It's not stored in the database at all - the External Method object you add/edit through the Zope management screens is primarily a pointer/wrapper to a method in a module in the Extensions directory. The Edit button in essence acts similar to the reload(module) function in Python. Basically, Zope (and Python) don't have a way of knowing the code in a module has changed unless it's explicitly reloaded, which is a good thing. .jPS | jeffrey(a)digicool.com zope, through the web. www.zope.org

Re: [Zope] Access to DTML Document properties

Thanks for a very fast reply, however it doesn't work. I'm still getting: Error value: 'string' object has no attribute 'title'. This is what I'm trying to do: A DTML document (index_html) has a property art1 which has an ID for another DTML document as value (type: string). In index_html I use:  which renders the article. I can of course use  in the actual article, but I rather don't. So I'm still banging my head in the wall after hours of trying to accomplish this. Can it be a bug with DTML documents??

OK - I think I get it, but how do I "convert" a string to a reference to an object, so that I can call properties associated with the object (DTML document). This should be possible, isn't it???

Apache Authorization

> Try Zap, the precompiled apache for Zope (Linux only). The zap.conf > file will probably have something your not including in your apache. I can't use another apache just for Zope. I looked into zap.conf and incorporated some changes into my httpd.conf. No way. Since the log file of RewriteLog remains empty, I believe no rewriting takes place, actually. I have about 30 virtual servers on that httpd, maybe there lies the problem? Also this is Apache 1.3.3, do I need Apache 1.3.4? -- Milos Prudek

If you're doing just a single query, you don't need the ';' (or its equivilent). If you're doing multiple queries, use  to seperate them. The DA will seperate the queries using this. This is equivilent to what command line or other SQL tools often do with the ';' character. > I remove teh ';' and Zope tells me that > "This was not a query." Nothing is being returned is what this means (or more basically, it wasn't a SELECT based query). .jPS | jeffrey(a)digicool.com zope, through the web. www.zope.org
