Is there an easy way to simulate the functionality of a while loop in DTML?

ZCatalog patch for international characters
by Holger.Cornelsen＠t-online.de 26 Jul '00

26 Jul '00

Hi, I had a lot of problems to get the ZCatalog search work for international characters like german Umlauts (üäö etc.) I have read all the tips about setting the locale and so on, but nothing worked. Now I found a solution: I've added this line at the top of lib/python/SearchIndex/Splitter.c #define __XPG4_CHAR_CLASS__ just before the include of ctype.h. Then I recompiled Splitter.c (simply said make in the lib/python/SearchIndex directory) which recreates the shared library Splitter.so The define changes the behavior of utility functions like isalpha so that they work for the current local set. Before I restarted Zope I had set the current local with: setenv LANG de_DE.ISO8859-1 setenv LC_COLLATE de_DE.ISO8859-1 setenv LC_CTYPE de_DE.ISO8859-1 setenv LC_MESSAGES de_DE.ISO8859-1 setenv LC_MONETARY de_DE.ISO8859-1 setenv LC_NUMERIC de_DE.ISO8859-1 setenv LC_TIME de_DE.ISO8859-1 setenv LC_ALL de_DE.ISO8859-1 Then I restarted Zope and reindexed the ZCatalog and now I can find words with german Umlauts :-) I'm working on a Sun Sparc with Solaris 8 using gcc. Hope this tip helps Holger

Inside the constructor code (i.e. inside "__init__"), objects do not yet have an acquisition context; they are not yet acquisition wrapped. This means, they do not yet have any of the acquisition attributes: aq_acquire, aq_base, aq_self, aq_parent, aq_inner. When they are later accessed, they are not returned themselves. Rather, an acquisition wrapped version of the object is returned. The wrapper provides the attributes above. "manage_permissions" obviously requires obviously requires its "self" to be a wrapped object. If you have access to the correct acquisiton context (i.e. the folder, where you will instantiate the instance), you can wrap the object yourself: self.__of__(context).manage_permissions(....) Or you must postpone the "manage_permissions", until you can reaccess the object in the correct context. Dieter

simple dtml-if question
by joel grimes 26 Jul '00

26 Jul '00

How do I do this? I have a table with a field called SerialNumber. I want to test it for null and return a non-breaking space if it's null. Here's what I tried: <dtml-if "SerialNumber = null">  <dtml-else><dtml-var SerialNumber> </dtml-if> Doesn't work (be nice-I'm new). I've tried various combinations of quotes - no quotes but apparently haven't hit it just right yet. What I'm trying to do is stick SOMETHING in an empty cell so netscape doesn't remove my borders when it encounters the empty cell - is there an easy fix?

OK, I think I have a workaround to the pcgi problem....
by Bill Anderson 26 Jul '00

26 Jul '00

I now have it working again. Steps I took -------------- o Use the pcgi directory from 2.1.6 o Put "PCGI_CLOSE_FDS=0" in Zope.pcgi o rerun w_pcgi.py This seems to be working, though I haven't rebooted the machine.... The real solution is that DC should fix the new pcgi .... I would like to know why all of a sudden, I need the PCGI_CLOSE_FDS=0 bit, especially. -- Do not meddle in the affairs of sysadmins, for they are easy to annoy, and have the root password.

I need to know if i can change the setting when i create a folder in the zope. Because i create a folder and automaticly that create a file index.php3 with some data. I want to know if i can change the data or setting the data that this index.php3 have into. <dtml-var standard_html_header> <h2><dtml-var title_or_id></h2> <p> This is the <dtml-var id> Document. </p> <dtml-var standard_html_footer> Thank you very much,

Joel that's really an HTML question. Use <BR> in every table field that contains only dtml tags. It isn't required if there is any text in the table field. Alan Capesius, MCSE Technical Support Engineer Sysmex Corporation of America capesiusa(a)sysmex.com

RE: Slow ODBC source

I'm using an Access DB on NT Server without any trouble. It is very fast. How large is the data you are retrieving? (bytes per record I mean) My apps are typically running on a MDB with 10,000 records I've noticed some issues that relate to Access queries. Here they are in the order I'd check them: 1) If Zope is running in a DOS window (haven't used it on 98) you might be running into a background processing problem. Use a PIF file to start it and make sure that Background processing is allowed. There is a checkbox to suspend in background I believe. What happens is that the app gets shut off when if doesn't have the focus and runs extremely slow if at all. Also your performance settings in the system tuning are may be set to provide foreground apps higher priority. 2) The DB should be on the same machine as Zope 3) The way in which queries are built can cause some problems. You may want to create a query that presort & preselects the results you want to obtain and then use that query as your data source in the Zope SQL Method. That way the results are pre-indexed and return quicker. This provided me a 97% performance improvement. (3 minutes down to 5 seconds) For Example: table->join query sorted by name->ZSQLMethod instead of table->ZSQLMethod (join sort) 4) You may want to run the Access database analysis tool and see if it recommends indexing. 5) You can adjust the number of records returned to improve performance in some cases. Sorry I'm an NT guy, and I agree 98 is for home user desktops not servers, NT workstation should be the bare minumim at the desktop IMHO. I don't want to get into the third grade OS wars either. It certainly isn't worth it to me to go thru the learning curve to switch to unix. The migration to NTW is much more tranparent.
