If I have a complex expression for X and it needs to be changed then it will have to be changed in two places. If I forget to update it in both places I would create a bug.

Making ZCatalog catalog the results from a ZSQL query
by Ivan Raikov 27 Jun '00

27 Jun '00

Greetings, How can I make a ZCatalog object to catalog the result set produced from a ZSQL method? I'm subclassing ZCatalog and replacing the default manage_catalogFind with a DTML method which in turn invokes a ZSQL method, but I get an error, "You are not authorized to access SQLPatientSearch." (SQLPatientSearch is the ZSQL method). I think I've set all permissions right, so I don't know why I get this, but I was wondering if someone can come up with an easier way to do this. Thank you very much, Ivan Raikov

Slow File Access With LocalFS
by Rob Pratt 27 Jun '00

27 Jun '00

Hello. I'm using LocalFS to reference a large collection of mp3 files. (I figured it was probably a good idea not to upload the whole shebang to the ZODB, so I just added a LocalFS object to reference the top directory of the collection.) When I try to download a file by calling the Zope object (for instance, http://zopeserver/LocalFSObject/mp3file.mp3) it takes 30 seconds for the average mp3 file to start streaming. Other files, i.e., way smaller ones, like 4K playlist files, download very quickly. Is Zope or LocalFS choking on the large files? Is there some work-around I'm missing?

Can't override standard_error_message on NotFound?
by matt 27 Jun '00

27 Jun '00

I'm having some problems with standard_error_message on 2.2.0b2. According to the mailing list archives I should be able to override NotFound errors (I even cut-n-pasted http://www.zope.org/standard_error_message/view_source into my own standard_error_message in case I was missing something) but requesting a nonexistent object still gets me what appears to be a built-in page. Is there something else to do?

STUPID_FILE_LOGGER
by Andy McKay 27 Jun '00

27 Jun '00

Hi, Im trying to run Zope on Win2k and use the stupid_file_logger. No matter what I seem to do to the command line or z2.py I still get the logs going to stderr (ie ms-dos console). Can anyone help? Here are command lines I have tried: "C:\Zope\bin\python.exe" "C:\Zope\z2.py" -D STUPID_FILE_LOGGER="c:\\zope.log" %1 %2 %3 %4 %5 %6 %7 %8 %9 "C:\Zope\bin\python.exe" "C:\Zope\z2.py" -D STUPID_FILE_LOGGER="c:\Zope.log" %1 %2 %3 %4 %5 %6 %7 %8 %9 "C:\Zope\bin\python.exe" "C:\Zope\z2.py" -D "STUPID_FILE_LOGGER=c:\zope.log" %1 %2 %3 %4 %5 %6 %7 %8 %9 etc.. I was hoping to write my own Logger, but when they didnt work to well I thought using the stupid_file_logger would suffice... Thanks.

ZWiki/Structured Text formatting surprise
by Chris Withers 27 Jun '00

27 Jun '00

Hi, Just noticed that (_.None,_, gets rendered as (.None,, in a structrued text wiki. Not useful :/ I've got around this by doing ('_'.None,_, but that's not really the right idea. Does anyone know of the proper way of escaping this? cheers, Chris

Yes, I noticed that too. I don't know if Amos will get to this by 2.2 final - I'll forward this to him though. Thanks!

Re: [Zope] Generating products that perform a smart clone of a master site?
by Hamish Lawson 27 Jun '00

27 Jun '00

David Thank you for your reply. > With ZClasses you can use the Zope security support to control who > updates what. However, currently ZClasses can only go in the > Control_Panel/Products folder. This means that all tutors will see > the products/classes used by all other tutors, which you say you wish > to avoid. I may have misled you about what I meant by the alien stuff that I wanted tutors to avoid seeing. I envisaged turning a tutor's site into a product that could be instantiated. In order not to make copies of static files, I reckoned that each folder in the tutor's original site would have to be made into its own ZClass in order that the static files that were missing from instances of the site could be found through inheritance. I'm happy with a tutor's site being moved into the Products folder; the stuff I wanted tutors to avoid seeing wasn't other products, since I think it should be possible to provide them with an interface that takes them straight to their own product. Rather I wasn't sure whether it was possible to turn a tutor's site into a product that used folderish ZClasses instead of ordinary folders, yet still have it feel like their old site. One issue with what I'm suggesting is this idea of every folder in the tutor's productised site really being a folderish ZClass. I'm bothered by this profusion of ZClasses. I think what I really need is the concept of prototype folders, whereby if a folder in an instance of the site didn't itself contain the required object, its prototype folder would be looked in instead; the folders in the product would be just ordinary folders rather than individual ZClasses, and folders within the product instances would all be instances of a single PrototypedFolder class (though obviously pointing to different folders as their prototype), thus drastically reducing the number of classes required. But I don't know whether such a prototype mechanism exists for Zope. Hamish Lawson University of St Andrews, Scotland ____________________________________________________________ Do You Yahoo!?
