Pythonscripts with reduce and zip
by Jørgen Hermanrud Fjeld 31 Jul '01

31 Jul '01

Hi. Hoping to do a little functional inspired programming involving reduce, I hit the wall in a PythonScript. Why aren't reduce and zip in the allowed safe_builtins, or why haven't a safe_reduce or safe_zip been made in ZopeGuards ? -- MVH Jørgen H. Fjeld

'Netscape style.css recursion' & Zope - Gotcha
by Chris Hinds 31 Jul '01

31 Jul '01

Hullo! I'm sure this will be obvious to some, but it took me the best part of a morning to figure out so I thought i'd post it anyway... I had a problem with Netscape (on linux) going into an infinite loop looking for a stylesheet when retrieving a non-existent url from zope. Here's why: Imagine serving up a page on http://127.0.0.1:8080/foo/bar <html> <head> <link rel="stylesheet" href="style.css" type="text/css"> </head> <body> <p> This is the index_html Document. </p> </body> </html> split up into standard_header_html and standard_footer_html as expected. Now visit a non-existent url eg http://127.0.0.1:8080/fu/bar Zope now serves up standard_error_message eg <dtml-var standard_header_html> oh dear, an error has occurred... <dtml-var standard_footer_html> This causes Netscape to retrieve http://127.0.0.1:8080/fu/bar/style.css which of course it can't find, so it tries again, and again.... (_duh_) So the moral of this story: - In line you style sheets? - use an absolute link to style.css not a relative one? - have a more independent standard_error_message page? - get Zope to redirect to a standard error page rather than inherit it? Hope someone finds this useful! regards, Chris.

CoreSessionTracking and lists
by Milos Prudek 31 Jul '01

31 Jul '01

I would like to assign a list to a variable in CoreSessionTracking. This fails: <dtml-call "data.set('varname',"["1"]")> But in python, I can do an assignment a=["1"] I tried to play around with single and double quotes, but to no avail. What am I failing to understand? -- Milos Prudek

Unable to access AUTHENTICATED_USER in DTML method after declared as public
by Dirksen 31 Jul '01

31 Jul '01

Hi, When I declare the DTML method index_html as public, like this: security.declarePublic('index_html') The index_html complains unable to access REQUEST.AUTHENTICATED_USER. Is it intentional to remove this variable when some method is declared as public? How can I determin if the visitor has logged in in a method that I have to declare public?

forcing all pythonscripts to recompile.

upgrading a test system to 2.4, and I'm getting a lot of 2001-07-31T07:00:41 PROBLEM(100) Script (Python) Object "lookup_partner" needs to be recompiled. ------ 2001-07-31T07:00:57 PROBLEM(100) Script (Python) Object "header_request_variables" needs to be recompiled. recompiling every python script in the system by hand is going to be a complete pain in the bottom - is there a simple-ish way to force them to all be recompiled? Nothing shows up in the 2.4 release notes or migration guide... Anthony

New restricted python - How to use in my Product?
by Christian Theune 31 Jul '01

31 Jul '01

Hi. In one of my products i use following code: import rexec r_env = rexec.RExec() selected=r_env.r_eval(self.default) that was zope 2.3 and python 2.0. With Zope 2.4.0 there is the new RestrictedPython module with this "expression" thing, but I can't find any useful documentation on how to use that. regards Christian -- Christian Theune - ct(a)gocept.com gocept gmbh & co.kg - schalaunische strasse 6 - 06366 koethen/anhalt tel.+49 3496 3099112 - fax.+49 3496 3099118 mob. - 0178 48 33 981 reduce(lambda x,y:x+y,[chr(ord(x)^42) for x in 'zS^BED\nX_FOY\x0b'])

FTP automangling file extension: semi-working proof-of-concept
by Jean Jordaan 31 Jul '01

31 Jul '01

Hi Joel I've also toyed with ideas related to this, though I wasn't looking at the file extension -- since my editor is Vim, not DreamWeaver. (When I have to work with designers who use DW, I just use ids that end in '.htm'.) My dream was rather to extend the "data block" parsing that Zope does when passing objects in and out via FTP or WebDAV. Specifically, Python scripts arrive looking like this: ## Script (Python) "formatContentLayer" ##bind container=container ##bind context=context ##bind namespace= ##bind script=script ##bind subpath=traverse_subpath ##parameters=page_id ##title= ## ''' Enumerates the positioning of the content <div>s and the backgrounds. ''' I'd love it if I could create new objects on the filesystem, and have Zope create them in the ZODB when I upload. The data block for a DTML method might look like: ## DTML Method "sendMail" ##title= ## <dtml-comment> .. and so on Zope should look for a factory for the meta-type on the first line, and create the object if successful, or fail to upload if unsuccessful. To accommodate non-Zope-aware FTP- and WebDAVing, this behaviour should happen on ports of their own .. eg. localhost:8021 for normal FTP and localhost:8121 for superFTP? (I suspect I'm drifting in the direction of something like FlareLang http://flarelang.sourceforge.net/prog-overview.html here, with the objects represented as XML on the filesystem. That might mean something like: <object> <meta_type>Script (Python)</meta_type> <id>formatContentLayer</id> <bindings> <binding>container <binds>container</binds> </binding> <binding>namespace </binding> ... </bindings> <parameters> <parameter>page_id</parameter> </parameters> <title></title> <body> ''' Enumerates the positioning of the content <div>s and the backgrounds. ''' ... </body> </object> ) Regards, Jean

Successfully implemented international characters in Zope 2.4?
by Francis Potter 31 Jul '01

31 Jul '01

Hi there, Has anyone successfully implemented international characters in Zope 2.4? I need to manage web content that's in Japanese, so need to be able to take Japanese text that's copied-and-pasted into a textarea (in Internet Explorer), store it in the ZODB somehow and return it in DTML or ZPT pages. I tried to install the Unicode patch from zope.org, but my hunks of patching failed. Any generic suggestions as to the best path to take? --- Francis Potter --- francis(a)helium.com --- desk +1 (415) 826 3646 --- cell +1 (415) 301 5162

precondition with File: Python Script does not work ?
by greulen＠freeler.nl 31 Jul '01

31 Jul '01

Hi I have a page with downloadable files and wish to count the downloads. I found a 'precondition'-option with the File object. This presummably calls the Method or Document specified before download wil start. The precondition is: counter_download(thefile='zip') In the same folder I have specified the counter_download as a Python Script: parameter: thefile if thefile=='doc': context.manage_changeProperties(doc_downloads=context.getProperty ('doc_downloads')+1) if thefile=='zip': context.manage_changeProperties(zip_downloads=context.getProperty ('zip_downloads')+1) return "ok" And the same folder also has these properties defined. The Python Script works fine when I test it and also the downloads are ok. However, the counting does not happen ?! Any ideas ? Regards Gijs
