Who is uid 506?
by Stephen Nosal 26 Jul '00

26 Jul '00

Folks - I've installed Zope 2.2 (binary rpm) on my Linux box (suse 6.4) and I notice that many files are owned by uid 506. I don't have a uid 506 on my box. Should I create a zope user with this id? Should I ignore it? - Steve __________________________________________________________________ Get your Private, Anti-Spam, Free Email at http://e3mil.com and Step into a Friendly Universe!

Need for "aq_base" in DTML (was: Re: [Zope] Dumb DTML question - existance check of an object) (was: Re: [Zope] Dumb DTML question - existance check of an object)

If not, create it. It is easy, if you are a bit sloppy. * Access to "/": "PARENTS[-1]" * Existence check: "_.hasattr(object,what)" NOTE, that this is the sloppy part. - "_.hasattr" will return true, if "object" has attribute "what" (that is what we want) *OR* when it has acquired such an attribute (we do *NOT* want that here). What we would need is a DTML accessible version of "aq_base". This is trivially handled by an external method. - it returns true, when there is such an attribute. This may not be a folder. You can check "meta_type" to see, it is indeed a folder. * creation: "manage_addFolder" look in the ZDP's (http:zdp.zope.org) object reference for the function's signature. I think, this info is available in the Zope 2.2 help system, too. Dieter

There is jpython, which is a python interpreter written in java, which I guess can access AWT/Swing classes. So you could do the GUI that way. I don't think there is a tk in java. See www.jpython.org for more. There is or was? also a TCL/TK plug-in. It seems dead now. I don't know what the heck is going on with Scriptics. Ajuba? Huh? Or (on a roll now) you could use the X version of Python/TKinter and remote the display using VNC, or one of the Java X servers. -- cary > Gijs > > > -----Oorspronkelijk bericht----- > > Van: tim(a)zope.org [mailto:tim@zope.org]Namens Tim Cook > > Verzonden: woensdag 26 juli 2000 5:03 > > Aan: Zope List > > Onderwerp: [Zope] Python/Tkinter & Zope > > > > > > Has anyone used this combination for GUI inside a Zope app? > > > > -- Tim Cook -- > > FreePM Project Coordinator - http://www.freepm.org > > OS Healthcare Alliance Supporter - http://www.oshca.org > > > > _______________________________________________ > > Zope maillist - Zope(a)zope.org > > http://lists.zope.org/mailman/listinfo/zope > > ** No cross posts or HTML encoding! ** > > (Related lists - > > http://lists.zope.org/mailman/listinfo/zope-announce > > http://lists.zope.org/mailman/listinfo/zope-dev ) > > > > > > > --__--__-- >

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

Re: [Zope] problem with manage_permission

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? Thanks, Joel ________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com

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.
