problem with ads.py
by WWW Admin 10 Feb '99

10 Feb '99

hi, i'm currently reading through the "A Technical Introduction to Object Publishing with Zope". included in this interesting read is an example ads.py. when i execute ads.py via the shell i get no complaints however when i try to add ads.py as an external method in zope with the following paramaters Id: adflipper Title: Function name: Python module file: ads and click on the add button i get this error message: "The specified object, was not found in module, ads." ok, so i tried calling some of the functions inside ads.py by entering them in Function name: but i basically got the same complaint. this is the first time i fooled with external methods so i'm probably making some very basic mistake but unfortunately i can't seem to figure out what it is. i put ads.py into the extensions folder. thank you to all who have provided answers to my questions in the past! regards, mark --------------------------------------------------------------------------- webman | _ beehive GmbH | ASCII ribbon campaign ( ) berlin, Germany | - against HTML email X http://www.beehive.de | & vcards / \

Re: [Zope] ZServer: Www-Authenticate header not passed

John> if user is None and roles != UNSPECIFIED_ROLES: John> self.unauthorized(realm,debug_mode) I see what you're saying, however since my function returns None, it should work. The reason I reported this as a ZServer bug is because when using ZopeHTTPServer everything works fine and the Www-Authenticate header is set correctly. The header is just not produced when publishing the same module using ZServer, which is why I'm blaming ZServer (although I haven't delved too deeply into the code to work out the exact problem). - Andrew -- #!/usr/bin/env python print(lambda s:s+"("+`s`+")")\ ('#!/usr/bin/env python\012print(lambda s:s+"("+`s`+")")\\\012') print(lambda x:x%`x`)('print(lambda x:x%%`x`)(%s)')

The documentation is not as clearly labeled as it could IMO, bibliographic and full-text search capabilities really need to be developed for Zope. All info sites really do need a search engine...

When documentation is written, please consider that it may be desired to use to show one's boss certain concepts. I don't mean to constrain here, but remember that most bosses will be at Zope Zen level 0.1. The more technical the info, the less need for limiting Zope-Speak. I'm supposed to give a talk about using Zope here at work soon. I'm almost clueless as to how to talk to clueless Zope users like myself. Anyone else in this boat, willing to work together to try to write something along these lines? > I think that the Product API tutorial helps. Very useful! Need More Input! Such as a folderish Product. Or a Tabula-ish product. We want to implement Computed Attributes (or whatever the heck they are called) for TinyTables. And remember that the more descriptive comments there are in the Zope sources, the fewer questions dummies like me will be asking... > I look forward to a better documentation process that will help more people > get the most out of Zope. Please, please, please provide modification dates on your documents. This is a VERY helpful feature when one is browsing oft-browsed sites. If no mod-dates are available, one tends to either unnecessarily re-read old documents and assume that what is new stuff has already been read. Also, by providing a mod-date for documents, it can become very easy to create a 'databased' What's New search where one can fill in the the What's New in the Last n Days, etc. not to mention sortin by mod-date... Thanks! Kent

In the previous versions of calendars that we've done, we've hooked it to Z Table (formerly Tabula) and done an index on the date field used. It winds up taking a lot longer to render the HTML table than cough up the results :^) --Paul

aqcuisition / symbolic links question
by WWW Admin 09 Feb '99

09 Feb '99

hello all, i have a set of documentation related to routers which would be interesting to both our isp division as well as our network support division. since each division has their own folder aquisition would not work for easy inclusion of text via includes. so my question is: does zope have an equivalent to a unix symbolic link? regards, webman --------------------------------------------------------------------------- webman | _ beehive GmbH | ASCII ribbon campaign ( ) berlin, Germany | - against HTML email X http://www.beehive.de | & vcards / \

- OO paradigm
by Michael Bernstein 09 Feb '99

09 Feb '99

I've been examining Zope with quite a bit of interest for a while now, and I have a question about the basic architecture: The object hierarchy seems to be 'exact', that is, strictly exclusive. No object can appear in more than one branch of the tree. However, In many cases, user oriented design requires several alternative navigation hierarchies, which would require objects to inherit from more than one branch. An example would be an event calendar, where events can be organized chronologicaly ( Years>Months>Days) but also according to an event category heirarchy (All events>entertainment>music>concerts). These heirarchies only intersect at the leaf node of an individual event. Most product catalogs can be profitably organized using multiple heirarchies as well. So how would you do this in Zope? you could of course represent the alternative heirarchies by branching off the bottom of the primary, or as folder properties, but that doesn't seem as elegant or maintainable. perhaps the answer is some sort of 'pseudo heirarchy' object that could be placed at or near the top of the object tree. What do you all think? Michael Bernstein.

I really could use Confera Unfortunately as soon as we released UserDB we wound up getting questions about it.

Zope Upgrade and Zope Linux to Win: data.bbb
