Sorry my naive question, i am a zope newbie. According to the zope manual, i should get a file list of the current folder, using the dtml method: <dtml-var standard_html_header> <h2><dtml-var title_or_id> <dtml-var document_title></h2> <ul>Files <dtml-in expr="objectValues('File')"> <li><dtml-var id></li> </dtml-in> </ul> </p> <dtml-var standard_html_footer> but i get a blank page, header and footer only are displayed, even though there are files in folder (a page refresh has been done, to be safe) I am using Zope 2.5.1 So, my first question is: what is wrong in the above code? My second question: can one provide a simple code to all objects included into a folder? thank you -- max

EuroPython2002: Extention of Early-Bird registration
by Tom Deprez 01 Jun '02

01 Jun '02

Hi, Due to the fact that at the end of the early-bird date, lot's of people waked up and registered for the congress (and because of the possible internet problems caused by the bancruptcy of KPNQwest), we've extended the early bird until 9th of June. We hope that the doubters among us, will find this interesting now that they are still able to profit from the early bird registration. But be warned, this is the final date! At the moment we've reached a total of more than 150 people at the EuroPython congress. That's already nice for a first congress, but it should be more.... Don't you think you could make great deals with people over there? There must be somebody to whom you can speak about a certain problem. With 150 people, it must be possible to make some friends or to see some old ones back... It can't be that Europe has only such a small group of Python and/or Zope developers/users. What about people outside of Europe? Have you seen the talks? It must be worthwhile to pay a visit to the conference.... and if not... well enjoy the Belgian beer, chocolates and food..... that's something I'm sure you will never forget! And now the early bird registration has been extended, .... so if you had doubts earlier, throw them away and just visit EuroPython2002! Don't forget to visit the http://europython.zope.nl/interviews page, which will be regulary updated with new interviews of people comming to EuroPython2002. Regards, EuroPython Team.

ZPatterns on OS X

Oops. Never mind. After a bit of twiddling I managed to get the DynPersist extension to build properly. For some reason, the ZODB/cPersistance.h file doesn't properly reference ExtensionClass.h . After fixing that, things seem to be ok. Mind you, I'm wondering how my ZODB built properly now when I compiled Zope. Vic

Accessing attributes - object with 'implicit' period in id
by John Schinnerer 01 Jun '02

01 Jun '02

Aloha, I'm back with an example. My situation seems different than solutions in recent threads, and I don't see how the answers thus far apply (if they do). I'm looping through the results of a catalog search, displaying thumbnail images, caption, date, etc.. A thumbnail, linked to a full-sized image, is displayed for each result: ... <a href="<dtml-var imageURL>"> <img src="<dtml-var thumbURL>" border="0" alt="<dtml-var caption>"> </a> ... imageURL and thumbURL are properties of each gallery item which point to the actual image, and will be something like: /gallery/thumbs/C03Valley001.jpg I want to get the height and width attributes from each thumbURL item and use them in the img tag attributes. But: height="<dtml-var thumbURL.height>" does not work, giving: Error Value: exceptions.KeyError on thumbURL.height in "" I am assuming this is because in my situation all thumbURL items returned are objects with periods in their IDs. So it's choking on trying to find '/gallery/thumbs/C03Valley001.jpg.height' - is this the case? Or is there some other problem here? In any case, how do I access the attributes (like height and width) in this situation, where the period in the actual ID is 'implicit' in thumbURL? thx, John S. __________________________________________________ Do You Yahoo!?

Tell me more re python/zope
by John Schinnerer 01 Jun '02

01 Jun '02

Aloha, It is, to be more specific, the zope/python combo (and documentation thereof) that I am finding cryptic and mysterious. Python as a language by itself is (relatively ;-) clear for me. At this point I have little or no use for python by itself - but I do want to use it extensively with/in zope. So what I'd like is pointers to docs, examples, tutorials, etc. that any or all of you have found most useful for *your* python-with/in-zope enlightenment. thx, John S. __________________________________________________ Do You Yahoo!?
