RSSChannel and peeping at objects attibutes?
by tom smith 21 Sep '00

21 Sep '00

I'd like to do something like this... <dtml-in anObject> <dtml-in anObject's_attributes> <dtml-var attribute_name> <dtml-var attribute_value> </dtml-in> </dtml-in> ...is this possible, getting at all an objects bits. The reason why I want to do this is that I'd like to be able to get hold of the news stories content and include them in a web page. I'm using the RSSChannel, and I'd like to be able to <dtml-in myRSSChannel> <dtml-var title><br> <dtml-var description> </dtml-in>

Clean Zope source patch
by Pierre-Julien Grizel 21 Sep '00

21 Sep '00

Hi, I need to patch Zope source code to make an I18N module of my own work. The function I need to patch is Publish.py in lib/python/ZPublisher (only the publish function). I'd like to to it a 'clean' way, that is, without modifying the actual source code. To achieve this, I can copy the publish function into MyPublish.py, patch it, and, somewhere in the Zope source file hierarchy, put something the following statement : ZPublisher.publish = MyPublish Well, huh... This is theory. It doesn't work because I don't know where ZPublisher is actually imported into Zope, and, thus, where my affectation will really take effect. Does anyone knows how to do this ? Or perhaps someone knows a better way to "cleanly" patch Zope source ?..... Many thanks, P.-J.

Import class in External method
by Francois-Regis CHALAOUX 21 Sep '00

21 Sep '00

Hi, I had some weeks ago a nice discussion on " Howto import external class in an external method ". However, I use now the " http://www.zope.org/Members/4am/instancehome " method to run my site. This really cool ;) In these condition, I would like to use something similar to import modules. If I want import a class placed in **my Zope root** tree the question is : where to place this module to import it ? I put my module in " MyZopeRoot/Products/Foo/ " and the call in the external method is " from Foo.mymodule import * " or " import Foo.mymodule " but nothing works. I stress I have also created a __init__.py in " MyZopeRoot/Products/Foo/ " but nothing has changed. Any track, FR.

RE: [Zope] Catalog Searching

> But doesn't Catalog() return all objects in the Catalog? > Doesn't all the > meta-data for those objects have to be loaded into memory ratehr than > just the 50 that are actually needed? No, it returns a list-like object that load objects into memory only as the elements of that sequence are accessed. Objects are arranged in the right order within that sequence using the metadata cached by the catalog.
