Replacing an unicode string
by Florian Reiser 26 Aug '03

26 Aug '03

Hi folks, I have an unicode string: text = u'ABC<EURO>' Now I want to do a replacement of the string u'<EURO>' to u'\u20ac' (this is the euro sign). When I type text = text.replace(u'<EURO>', u'\u20ac') nothing happens, the string is still u'ABC<EURO>' How can I replace the tag '<EURO>' and insert the euro sign instead? Regards Florian Reiser

How the heck do I do this Python for Loop?
by Bill Hewitt 26 Aug '03

26 Aug '03

This has been driving me crazy for the last week...... I wrote a python script that loops through a directory called StyleBook and selects a particular stylesheet based on the Day of the week, the year and a parameter..... --------- example: --------- ## Look for Day Year (ie - Monday 2003) in the StyleBook Directory for i in container.StyleBook.objectValues('Style Sheet'): ## Check the TITLE of "i" against a preset variable and aparameter if i.title = DAYYEAR and i.stylesheetrequest == stylesheetrequest: ### At this point I have all the variables (47 total) except the ID :( This works - I get the proper Style Sheet.... I would *like* to then call a DTML Method against the values in the NAMESPACE of the object I found in the code above..... something like return container.StyleBook.i.loadStyle() but every variation I have tried doesnt work - I get an error telling me that "i" is not in the global NameSpace.... Could someone PLEASE help me through this one? I know it is probably very simple, but it is evading me... WPH

ExternalEditor and Zope's gzip compression, in Windows
by Ausum Studio 26 Aug '03

26 Aug '03

I just stumbled with a problem while working with both Zope's gzip compression and ExternalEditor: If you enable gzip in HTTPResponse.py, like this: use_HTTP_content_compression = 1 expect the problem that every time you click at the icon to launch the editor, Windows will start to ask for what to do with the to-download file. If you respond to open, then it will trigger the File Types dialog box, asking for the right app to open it. In other words, you'll be tempted to reinstall ExternalEditor. :) Any ideas of how to patch this? Thanks in advance, Ausum

[Ann] DocFinder 1.0: ask Zope about its documentation
by Dieter Maurer 25 Aug '03

25 Aug '03

It is often difficult to find accurate documentation about the Zope infrastructure. Often, I have written: look into the Zope source, its source documentation is quite good. However, as Zope's implementation language Python provides good introspection facilities, there is a better way: extract the documentation directly from Zope. That's what 'DocFinder' does. It analyses any Zope object inside a running Zope, determines which classes have been used in the object's makeup and provides information about their class level attributes: name, allowed roles, arguments, documentation strings. It provides (read only) access to to source code of Python implemented classes and methods, as well. What's new in version 1.0: * Direct access to source code of Python implemented classes and methods * Implemented as a single persistent <code>DocFinder</code> instance (rather than a DTML object and External Method pair) * Alternative URL-calling to document objects which intercept traversal * Now uses PageTemplates rather than DTML for presentation More information and download: <http://www.dieter.handshake.de/pyprojects/zope/DocFinder.html> Dieter

We recently installed Zope 2.6.1 on a RH Linux 7.2 server. When we attempt to start Zope on this server, we get the following message: ------ 2003-08-25T16:07:40 INFO(0) zdaemon Started subprocess: pid 5635 ------ 2003-08-25T16:07:43 INFO(0) ZODB Opening database for mounting: '144205064_1059403198.767560' ------ 2003-08-25T16:07:43 INFO(0) ZODB Mounted database '144205064_1059403198.767560' at /temp_folder ------ 2003-08-25T16:07:43 INFO(0) ZServer HTTP server started at Mon Aug 25 16:07:43 2003 Hostname: xxxxxxxx Port: 8080 ------ 2003-08-25T16:07:43 INFO(0) ZServer FTP server started at Mon Aug 25 16:07:43 2003 Hostname: xxxxxxxx Port: 8021 ------ 2003-08-25T16:07:43 PANIC(300) z2 Startup exception Traceback (innermost last): File /local/home/Zope-2.6.1-linux2-x86/z2.py, line 748, in ?

How do I ask Zope for the name of an uploaded file?
by Cameron Laird 25 Aug '03

25 Aug '03

I'll abbreviate this: in a Python script that processes a file upload, how do I express the name of the uploaded file-- that is, the name of the file the user selected with his browser? I expected I'd find this in something like context.REQUEST.get_header('CONTENT-DISPOSITION') or context.REQUEST.get_header('filename') or somesuch, but I'm just getting None from those. Note that this information is available only through the HTTP dialogue; as near as I can tell, it is NOT available through the context.REQUEST dictionary. I anticipate a couple of possibilities. One is that some- one will know immediately what I'm trying to say, and will give me the one-line answer I'm after. The second is that my description puzzles everyone. In that case, I'll happily detail a model that should make all this clear. I prefer to avoid the work, though, if it's un- necessary.

standard_error_message weirdness
by Erik Myllymaki 25 Aug '03

25 Aug '03

trying to customize my standard_error_message - Zope 2.6.1 on win32 (win2k server) IE 6 client. if I use the simplest possible dtml-method: MyError I get a zope internal site error: ...traceback NotFound: MyError ... so it seems it wants a complete HTML doc. so I change the standard_error_message to: <HTML><HEAD><TITLE>Simplest HTML Error Page</TITLE></HEAD> <BODY> MyError. </BODY> </HTML> But the wierd thing is it gets displyed once or twice, and then the IE internal error page takes over (404, 500 mostly)... I'm pulling my hair out here - any advice appreciated.
