IRC clients
by Jimmie Houchin 30 May '00

I haven't been to an IRC chat in over 5 years so this is pretty new to me. I also just built myself a new Linux machine for development and was not familiar with any Linux IRC clients. For those in a similar situation here is a little info on some Linux/*nix IRC clients. I think I'll try X-Chat as I use Gnome. We'll see. See y'all there tomorrow. By the way the links below came from Linuxberg.com aka Tucows. If you click on one it should take you to a page to direct you to the closest mirror. Hope this helps.

Previewing Temporary Images
by Chris Crownhart 30 May '00

30 May '00

I am writing an HTML form that is using the type=file attribute to collect an image from the user. I am also collecting other information and then formatting it on a page in a preview mode. I would like to allow the user to preview their data, with an image, before they elect to save it (in Zope). The problem, I think, is that the IMG tag needs a physical file to point to in order to render the image. Given that the image object is of type FileUpload, once the user presses the submit button, is there a way to display that FileUpload Image without actually saving it in Zope? Thanks for any suggestions, Chris

Building ZPyGreSQLDA on Linux
by Hung Jung Lu 30 May '00

30 May '00

Hi, I need help building the PostGreSQL database adapter on Linux. Sigh... why is installing everything on Linux such a nightmare? ZPyGreSQLDA installation is in such a primitive stage... I don't understand... it's like it's written to work with one very particular directory structure at the author's machine, and the heck with the rest of the world. :) Why not just write something to build the C Python module in place and then tell the user to move the compile C Python module (.so) to whereever it needs to be moved? The problem now is that the ZPyGreSQLDA/Makefile.pre.in has all kinds of settings of folder structures that don't match with my folder structure. I get the following error: (yes yes, I have played with PATH and the <prefix> variable mentioned inside Makefile.pre.in... and by the way, the FTP site ftp://www.eevolute.com/pub/python/ mentioned in README.linux no longer exists.) ---------------------------------------------------------- [hjlu@www src]$ make -f Makefile.pre.in boot rm -f *.o *~ rm -f *.a tags TAGS config.c Makefile.pre python sedscript rm -f *.so *.sl so_locations VERSION=`python -c "import sys; print sys.version[:3]"`; \ installdir=`python -c "import sys; print sys.prefix"`; \ exec_installdir=`python -c "import sys; print sys.exec_prefix"`; \ make -f ./Makefile.pre.in VPATH=. srcdir=. \ VERSION=$VERSION \ installdir=$installdir \ exec_installdir=$exec_installdir \ Makefile make[1]: Entering directory `/u/c2/hjlu/lwc_zope_current/lib/python/Products/ZPy GreSQLDA/src' make[1]: *** No rule to make target `/u/c2/hjlu/lwc_zope/lib/python1.5/config/Ma kefile', needed by `sedscript'. Stop. make[1]: Leaving directory `/u/c2/hjlu/lwc_zope_current/lib/python/Products/ZPyG reSQLDA/src' make: *** [boot] Error 2 --------------------------------------------------------- Not that I like to complain, but every time I run into a trouble, dozens more people will run into the same problem. I still remember when I complained about some other database adapter, someone popped up and said "I have been running it with ZERO problem"... and 3 months later the same person was screaming about the very database adapter that that supposingly had "ZERO problem". Things do improve. I remember the days when Python couldn't be installed easily, but nowadays even the Tcl/Tk part of Python has been absorbed into a single installer on Windows system. And it's as trivial as one-click-does-it-all. PostGreSQL has been around for a while, now. And I guess we all could do a little bit more towards making the installation of the adapter easier.

Use of lambda expression in DTML
by Nick Drew 30 May '00

30 May '00

I'm a newbie zopista, and python for that matter... In brief: I get a NameError when invoking "filter(...)" from DTML. I thought this was a built-in python method, so I'm a bit puzzled. In detail: 1) I want to display a dtml-tree of my folder hierarchy, but I want to exclude all Zwiki discussion groups. 2) In my index_html for the top level folder, I have the following: <dtml-tree Outline leaves=dtcTemplate > <dtml-if tree-item-expanded> <dtml-if expr="objectValues(['Folder'])"> <IMG SRC="<dtml-var BASE2>/Outline/OpenBook.gif" ALIGN="TOP" BORDER="0"> </dtml-if> <dtml-var title> <dtml-else> <dtml-if expr="objectValues(['Folder'])"> <IMG SRC="<dtml-var BASE2>/Outline/ClosedBook.gif" ALIGN="TOP" BORDER="0"> </dtml-if> <dtml-var title> </dtml-if> </dtml-tree> which is cribbed straight from QuickStart. 3) I only want to ignore Zwiki groups, but they are out-of-the-box folders, so I can't filter on meta-class. 4) My approach is just to add a property to the Zwiki folder ('blockTreeBranching') 5) In the dtml-tree tag, I change it to: <dtml-tree Technical leaves=dtcTemplate branches_expr="filter( lambda f: not f.hasProperty('blockTreeBranching', false), objectValues(['Folder']) )"> which, all things equal, should DoTheRightThang. 6) The code can be published, but when I view it, it spits out a NameError, choking on "filter". Argh. Ideas gratefully recieved... Nick HyperSpace Ltd,Birmingham Research Park, Edgbaston, UK, B15 2SQ (e) hyperspace(a)btinternet.com (t) +44 (0)121 414 7019

dtml-tree and REQUEST.form
by Pierre-Julien Grizel 30 May '00

30 May '00

Hi, I'm currently implementing a tree using... dtml-tree. In the document I use, I just have the tree and a table which desplays results according both to the tree state and some form data (passed through REQUEST.form). I.e. my URLs should look like the following : http://xxx.xxx/xxx/yyy/zzz/MyPage?MyVar=toto when I first open the page, and it SHOULD look like http://xxx.xxx/xxx/yyy/zzz/MyPage?MyVar=toto&e-tree=<tree-stuff>. You guess - it doesn't look like this at all. This because the <dtml-tree> tag doesn't use the REQUEST.form dictionnary data to build its URLs. Instead, it just discards, in the URLs it builds, every single GET variable you wish to use. I'm currently patching the TreeTag.py file to support the REQUEST.form data, but I'd like to know if someone ever had this problem, and maybe corrected it - I hate patching. Also, if there is no other solution, I'd like to know if there are peolple intersted in this patch. Thanks, P.-J.

ZClass Error
by Pete Kazmier 30 May '00

30 May '00

I've created a ZClass that was subclassed from a custom Python class. Everything is working well, thanks to the help of this mailing list, but I am having one problem that I am unable to figure out. If I add my subclass to the root of my Zope world, then I am unable to click on the Properties tab while managing it. However, if I create my ZClass anywhere else (ie not in the root), everything works fine. Here is the traceback that I receive. Any help would be appreciated, I am also using 2.2.0a1. Thanks.

ZClass and python subclass __init__ method
by Pete Kazmier 30 May '00

30 May '00

According to the Zope Developer's Guide, when you create a ZClass by subclassing from custom python classes "your subclass's __init__ method will not be called when instances of the Z Class are created." Could someone help explain why my __init__ method is being called? Is the document just out of date? What should be the correct behavior? Also, is there a simple way of detecting from my python class's init method if it is being called within the Zope environment? I'm trying to keep my python class as non-Zope centric as possible because I use that class in other programs as well. Oh, I am using the 2.2.0a1. Thanks, Pete -- Peter Kazmier http://www.kazmier.com PGP Fingerprint 4FE7 8DA3 D0B5 9CAA 69DC 7243 1855 BC2E 4B43 5654
