Advanced DTML Question
by James W. Howe 02 Mar '00

02 Mar '00

I'm trying to write a DTMLMethod which will write out a list of data items found from a catalog, sorted in alphabetical order. This is easy. Basically I do something like this: <dtml-in "Catalog(meta_type='foo')" sort=someAttribute> <dtml-with "Catalog.getobject(data_record_id_)"> <dtml-var objvar1><dtml-var objvar2> ... </dtml-with> </dtml-in> I've got this working, no problem. Now, since the list of these items might be somewhat long, I want to build a simple index at the top of the page and use page anchors to get to key points on the page. Basically I'm going to display the alphabet and when the user clicks on a letter, the page should scroll somewhere in the vicinity of an item which starts with that letter. To that end, what I would like to do is have some code inside of my dtml-in loop which gets the first letter from the current entry, checks to see if an anchor for that letter has been written, if not, a new anchor tag is inserted into the stream. My problem is I don't really know how to code this up. It seems like maybe that at least some of this should be done at the Python level but I'm not quite sure how to split up the functionality. Has anybody done anything similar who would be willing to give me some advice as to the best way to go about solving this problem? Thanks. James W.

SQL Methods being called more than once
by Jerry Spicklemire 02 Mar '00

02 Mar '00

It looks like you are indeed running the query multiple times. Unless you are changing the data at some point internal to the process, which would require your to "refresh" the results in order to have current data, you could try: <dtml-in sqlMethod query=start_query> Do some stuff Do some more stuff Do even more stuff </dtml-in> Youd be "recycling" the result set, and sparing the DB backend.

ZOPE! I HATE YOU!
by jiva＠devware.com 02 Mar '00

02 Mar '00

It used to be that I was so open minded when it came to web technologies. I used to say "Oh yeah, pick whatever you want, we can do it in that." I used to say "No problem! We can use your scripting technology! It's just as good as any other." And I would, and they would, and we did. And we'd all stand around and say "Yeah man... that's cool." And then Zope entered my life. And NOW I simply can't think of virtually any project that Zope wouldn't do a better job of serving than those *other* technologies. It's very frustrating when every time you see a project you think "Oh, Zope would make that SO much easier!" Especially any time someone mentions the word "Database" and "Web" in close proximity. The truly frustrating part is staying focused on the problem-space when you have such a fun technology to play with. Now in some ways I'll admit, this is an exaggeration. Obviously, there ARE lots of cases when Zope isn't appropriate, but I just wanted to shout out a big thanks for developing such an awesome system that makes developing apps so easy to do. Now if I could just get my mind off of it's possibilities long enough to evaluate those OTHER technologies objectively, then I'd be in good shape. ;D -- Juall's Law on Nice Guys: Nice guys don't always finish last; sometimes they don't finish.

Zope stopped working after working once...
by Eric L. Walstad 02 Mar '00

02 Mar '00

Hello all - I am unable to connect to my Zope 2. I am running Linux 2.2.14, with Apache I am new to Zope and pretty new to Linux I installed Python 1.5.2, then installed Zope using "python w_pcgi.py" I entered ./start It worked... for a while... until I shutdown... When I restarted, Zope wasn't available. I went back to the Zope directory and tried ./start again but the script seems to lock up after displaying the following: ------ PROBLEM(100) ZServer Computing default hostname ------ INFO(0) Zserver Medusa (V1.13) started at ... Hostname: frankenstein.energywright.com Port:8080 ------ INFO(0) ZServer FTP server starte at ... Authorizer:None Hostname: frankenstein.energywright.com Port:8021 ------ INFO(0) ZServer PCGI server started at ... Unix Socket: /usr/local/Zope/var/pcgi.soc ------ INFO(0) ZServer Monitor Server (V1.5)started on port 8099 When I try to connect to http://192.168.1.100:8080/manage I get a "File does not exist: /home/httpd/html/manage" error in my Apache error_log I was so happy when I got it running, now I'm incredibly frustrated! Please help! I can supply my Apache conf files if necessary... Many Thanks, Eric.

Oedipus 0.06 released
by Andrew M. Kuchling 02 Mar '00

02 Mar '00

I've made a new release of Oedipus, a Python package for presenting data from the Open Directory Project. http://www.mems-exchange.org/software/python/oedipus/ In v0.06, The improvements to the ODP code itself are pretty minor. The major milestone is that, after some diligent sleuthing, Jean-Claude Wippler tracked down an obscure bug in MetaKit that I was tripping over. A patch for MetaKit 2.0 is included in Oedipus 0.06, so for the first time you can actually handle a complete ODP dump. You'd better have 400Mb of disk space for the resulting data file, though, plus 500Mb for the source XML files, plus 4-5 hours of processing time (at least on a 550MHz Linux box). The exported ZClass product still doesn't seem to work, though; if you untar it in a new Zope installation, no Product is added when you start up Zope. Anyone else notice this problem? -- A.M.

urgent! help! strange blockings
by Tino Wildenhain 02 Mar '00

02 Mar '00

Hello, I cannot get ride of those strange blockings of zope. This happens from time to time and leads some times to minutes without action from Zope. I increased threads pool and decreased it, I use a much bigger object cache (memory is not an issue on the machine) and I pured the database (with help of an extra machine) Zope stucks with about 18% processor use and does almost nothing at the moment. Any posibility for an dead-lock? Help is very appreciated! Configuration: Zope 2.1.4, ZODBC, Database-Size: 66MB (after purify) Some sessions with unsafed work, 50 threads for pool, NT 4.0 (ok, this sux, but we have to use ODBC with strange Databases) Tino Wildenhain

why doesn't this work with tree tag
by Andy Heath 02 Mar '00

02 Mar '00

In the depths of a tree tag I want to pick up a property of the "current" object without acquisition if the property isn't present. This code seems to work when used not in a tree tag but when its in a tree tag it still finds the property from higher up in the acquisition space. <dtml-with this only> <dtml-if rubbish> <dtml-var rubbish> </dtml-if> </dtml-with> What gives? How can I do this? The version below doesn't fall over if the property isn't present on that object, it just finds it by acq. Code below should fall over but doesn't ---------------------------------- <dtml-tree expr="lists" branches=objectValues sort=order> <dtml-if "meta_type=='Folder'"> <dtml-var title_or_id> <dtml-else> <dtml-if "kind=='discussion'"> <A HREF="<dtml-var listURL>"> <dtml-var title_or_id></A> <dtml-else> <dtml-with this only> <dtml-var rubbish> </dtml-with> </dtml-if> </dtml-if> <dtml-if listinfo> (<dtml-var listinfo>) </dtml-if> </dtml-tree> Andy sorry for so many q's. I promise to give back when I can. -- ------------------------------------------------- Andy Heath a.k.heath(a)open.ac.uk The Open University +44 (0) 114 2885738
