DCOracle - Oracle 8i - Solaris Sparc [Q]
by zope＠infosys.com.ar 23 Oct '99

23 Oct '99

Hi! I am trying to compile the DCOracle (the one that comes with ZOracleDA 2.1.0) on a Solaris machine. I am running Solaris7 with all the patches, Oracle 8i, Python 1.5.2 and Zope 2.0.1 When compiling I get that all the libs (the ones that are in the form -lnetwork -lcore4 etc...) are unknown. The Oracle software is working correctly, all the env vars are set, and I have tryied the same procedure on a Linux (redhat 5.2) machine running Oracle 8.0.5 and it worked. Is there so much difference between Oracle 8i (version 8.1.5) and Oracle 8.0.5 that I cannot get the DCOracle module to compile? I really need this working, so if anyone has any comment or answer, please... :-) TIA /B Bruno

Re: [Zope] Getting an object from its name

Hi, Thanks for your answers. I couldn't get it to work though. By the way, where does this indirection thing comes from? I had not seen it in any of the docs I've read! So my setting is: showImage1 (DTML Method) showImage2 (DTML Method) Folder/ Figure1 (DTML Doc) showImageDoc1 showImageDoc2 showImageDoc1: <dtml-var "showImage1(img = 'Figure1')"> showImageDoc2: <dtml-var "showImage2(img = 'Figure1')"> showImage1: <img src="<dtml-var img>"> showImage2: <img src="<dtml-var img>"> <dtml-var "_[img].title"> When accessing http://localhost:8080/Folder/showImageDoc1 I get: <img src="Figure1"> which is OK. BUT when accessing http://localhost:8080/Folder/showImageDoc2 I get: Error Type: KeyError Error Value: Figure1 So I tried to up the DTML Method showImage2 into Folder like this: showImage1 (DTML Method) Folder/ Figure1 (DTML Doc) showImageDoc1 showImageDoc2 showImage2 (DTML Method) BUT when accessing http://localhost:8080/Folder/showImageDoc2 I get: Error Type: KeyError Error Value: Figure1 Any ideas? NOTE: I've also tried: <dtml-with "_[img]"><dtml-var title></dtml-with> and <dtml-with "_[_.str(img)]"><dtml-var title></dtml-with> For both of them I get the same error! Thanks for your time!

Re: [Zope] upgrading a product
by Kevin Dangoor 23 Oct '99

Hi, Liz Sorry I didn't respond to this earlier... it's been crazy. Assuming you didn't make any changes to the KMNN that you have, you should be able to delete the old product, then install the new one. When you delete the product, your KMArticleStore and KMArticles will be broken (because the ZClasses will be missing). But, when you install the new version, the class-id is the same, so your instances will start working again. As always, though, make a backup of your Data.fs in case something goes awry :) These should be undoable changes to the ZODB though. The upgrade should be relatively painless. The thing I haven't figured out is a good way to upgrade when you've actually made changes to the product. Maybe there should be one product that defines ZClass base classes and another that wraps those. You create instances of the wrapper objects, and make your changes to the wrappers. That way, you can plug in new base classes without interfering with your changes. I haven't tried any of that though. Good luck!

Everytime I try to import the file, it says "already exists". Simply renaming the current product does not help as I then get "Permission Manage... already exists". I tried renaming those files, but was told that operation could not be performed on these file types. Could someone please be explicit about how to upgrade an existing product in newbie terms? Thanks in advance, Liz Pelletier

Re: [Zope] DTML Namespace confusion

Michel Pelletier wrote a message a few weeks back that explained things nicely. Basically, the first parameter is the "target" object (not sure if that's the right word), and the second parameter is the namespace. <dtml-if "some_condition"> <dtml-var "render_item(_.None, _, input_var1='value1')"> <dtml-else> <dtml-var "render_item(_.None, _, input_var1='value2')"> </dtml-if> Should do what you're looking for. Note that you don't need to pass REQUEST in, because it is a part of the namespace. Kevin

I think Edd does indeed mean reading in an RSS file from somewhere and publishing the headlines. As far as copyright goes, if someone is providing an RSS file, I think the intention is to allow people to list their news headlines on their own sites. This is not the same as putting the articles on your site though. This is just summary information. Companies like Reuters probably would not offer an RSS file. But, there are many, many sites that do (just see my.userland.com or the channels available for My Netscape). To an extent, the tools to display RSS files are already available... There's urllib for grabbing the files and XMLDocument for providing access to the information contained within them. If people are doing a lot of RSS syndication, it may be good to have an object specifically designed for easy manipulation of RSS. But, for now, it seems like the tools that exist are pretty powerful. Kevin

I've had this problem as well, and I have never seen a solution. To distribute KM|Net News, I just tarred up the .zexp file in an "import" directory and the external method in "Extensions". That way, the user just untars the file, and does an import. Kevin

RDF and Zope
by Tim Wilson 23 Oct '99

23 Oct '99

Hi everyone, I've spend the last couple hours trying to wrap my brain around the W3C's RDF spec. I actually just finished reading Tim Berners-Lee's new book which mentions RDF. Anyway, I'm wondering what, if any, relevance this has for Zope. Is there anyone who would be willing to offer some comments? My own thinking began as I considered how to display news headlines from different sites on my Zope site. After doing some reading I learned that RDF seems to provide some mechanism for making that easier. I really don't understand it yet, but it seems like some important work. I'd love to hear more about it from someone more familiar with RDF, XML, and related Python tools than I. -Tim -- Timothy Wilson | "The faster you | Check out: Henry Sibley H.S. | go, the shorter | http://slashdot.org/ W.

How quickly does zope respond.
by Jason Cunliffe 23 Oct '99

23 Oct '99

I am wondering how fast zope responds for others, and what tips you have to improve regular performance (hardware, software, config). When you start with a fresh Zope install, how many seconds (from mouse click) does it take: 1. To boot Zope 2. To enter the manage interface 2. To open index_html 3. To save the changes 4. To View this 5. Ditto for image uploads (say with 8K, 32K, and 64k Jpegs) What's your best? What's your worst? Can you suggest an approach to build in this kind of local-action performance checking via a DTML method which uses timestamps comparison. For example a method which I can toggle on and off at different levels of the hierarchy to create a history file of certain actions. Does this already exist? I've am testing Zope on two 'minimal platform PCs to check performance I can expect for clients in an upcoming project who I know will _not_ have the latest and best systems. My two current 'test' machines are: 1. P5-150Mhz,64Mb, Win95b 2. P233mhzmmx, 32mb, Win95b -laptop I've been experimenting with these in 3 ways: with Zope local to each machine, over a small ethernet LAN and remote over 56k modem to hosted Zope site (codeit). This is the other 'end' of the discussion I've been following about server performance.

RE: [Zope] Zcatalog and PrincipiaSearchSource with Zclasses ?

The DTML Method doesn't get called with the usual client and REQUEST objects, so the method has no means of obtaining the title, author and body parameters. You can do it with an External Method: def AllField(self) return self.title + self.author + self.body or you could make a property on you object that on every update gets filled with the contents of title + author + body. -- Martijn Pieters, Web Developer | Antraciet http://www.antraciet.nl | Tel: +31-35-7502100 Fax: +31-35-7502111 | mailto:mj@antraciet.nl http://www.antraciet.nl/~mj | PGP: http://wwwkeys.nl.pgp.net:11371/pks/lookup?op=get&search=0xA8A32149 ------------------------------------------
