And what happen if the Class A is in a package PA. Clabb B is in a package PB. How do you access the namespace of PA from PB ? When I have tried, the inherited methods from A where not visible from B, and I and to recreate a copie of the method. (which is ugly !!!). Any suggestion ?

Well by inheritance B has all the methods, properties etc you have in A. So the answer is yes, if A has the foobar method then B will have a foobar method.

Why do you see any need to turn ProxyRequests On? I run the ProxyPass too, but there is no need for the ProxyRequest and the Proxy module. Perhaps there lies your problem. -goe- >My configuration looks like this: > ><IfModule mod_proxy.c> >ProxyRequests On >#ProxyReceiveBufferSize 65536 >ProxyReceiveBufferSize 0 >CacheRoot "/www/proxycache" >CacheSize 5000 >CacheGcInterval 1 >CacheMaxExpire 48 >CacheLastModifiedFactor 0.1 >CacheDefaultExpire 5 >ProxyPass /paginas/ http://200.xxx.xxx.xxx:8080/ >ProxyPass /p_/ http://200.xxx.xxx.xxx:8080/p_/ >ProxyPass /misc_/ http://200.xxx.xxx.xxx:8080/misc_/ >ProxyPassReverse /paginas/ http://200.xxx.xxx.xxx:8080/ >ProxyPassReverse /p_/ http://200.xxx.xxx.xxx:8080/p_/ >ProxyPassReverse /misc_/ http://200.xxx.xxx.xxx:8080/misc_/ ________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com

Nested Tag Creation
by Andrew Kenneth Milton 18 Aug '00

18 Aug '00

I want to create a tag that has sub-tags. Now I know I can use blockContinuations to approximate this, but, I think it would be cleaner to be able to define tags that are only available within the context of the main tag (namespaces and all that). Is this possible? Without rolling my own parser ? I don't see a lot of tag products being released so I assume that this is not a widely used thing for Zope. -- Totally Holistic Enterprises Internet| P:+61 7 3870 0066 | Andrew Milton The Internet (Aust) Pty Ltd | F:+61 7 3870 4477 | ACN: 082 081 472 ABN: 83 082 081 472 | M:+61 416 022 411 | Carpe Daemon PO Box 837 Indooroopilly QLD 4068 |akm(a)theinternet.com.au|

manage_addDTMLMethod vs. manage_addZSQLMethod
by Hannu Krosing 17 Aug '00

17 Aug '00

Why does this work <dtml-call "_['testadd'].manage_addDTMLMethod('MethodId', 'Method Title','method text')"> While this does not: <dtml-call "_['testadd'].manage_addZSQLMethod('DB', 'DB', 'DB','DB','DB')"> (the database connection DB is there) I studies the Znolk product and found that it uses _setObject directly instead of manage_addZSQLMethod . Should I just wrap _setObject into an external method (to make it visible) and start using it or is there a simpler way ? ------------- Hannu

looking for DTML Property examples
by Jason Cunliffe 17 Aug '00

17 Aug '00

Hello I am looking for some basic examples on using Properties in Zope. For example: How-To write methods which put and get properties, and with these examples of accessing properties via URLs directly as wellas via custom methods. There must be a ton of examples _somewhere_, but somehow, I can't seem to find them and th ORA book is not out yet [praying hard for great index and LOTS of small examples thourhgt the text]. Thanks in advance for any links - Jason ________________________________________________________________ Jason CUNLIFFE = NOMADICS.(Interactive Art and Technology).Design Director

getting base classes's (super class) _properties tuple
by Daniel Rusch 17 Aug '00

17 Aug '00

Say I have a fully functional (and more importantly, working) Product will call A. I want to extend this Product's capabilities so I wish to derive another class from it, call it B. No problem, class B(A): ......... now in class B I want to add a new property. Is the a way of getting the base (super) class _properties tuple and just adding the new one to it. Since a tuple is an immutable object I can't do this: _properties=A._properties.append({'id':'RenderStandardHeader', 'type':'int','mode':'w'}) Any thoughts ???? DR

Amazing Disappearing Self
by Spicklemire, Jerry 17 Aug '00

17 Aug '00

Hi Zope Fans, Has anyone seen a case where acquisition works, but only in the topmost folder? The site I'm working on shows no problem on a test server, but upon moving to a production server any URL pointing to a subfolder, or a document contained in a subfolder returns an error (below). The production server is Red Hat linux, Zope 2.1.6 A Proxy (running on a separate server) re-directs URLS to the top folder of the Zope tree, just below "root". The oddest part is that elements available in the "root" (standard_html_header, and other elements called within) show up on the same "page" as the error message. It's as if Zope is working partially, but after displaying all the elements at the top of the tree, the silly document can't find itself . . . BTW, the raw URL (as seen in REQUEST) contains lot's of cookie garbage which may be causing the problem. I have added something like <base href="&dtml-relative_path;"> as suggested in some "How-Tos" at Zope.org. This got me to the point of having the top folder render correctly, which was better than I had seen up to that point. Alas, that's where progress stopped altogether. On the test server everything "just worked", the way you sort of get used to with Zope . . . The worst part is that some of the errors I'm seeing spill the guts of the cookie all over the browser screen. BTW, what does it take to get standard_error_message to actually do what the dtml implies, to substitute the contents of an error_message object, where it exists? Thanks, Jerry S.
