If you really get a string "['a','b']", you can strip off the leading and trailing brackets and the quotes and proceed as in the thread. You could also convert to a list of strings using eval() in an external method, but that would be overkill, I think. Cheers, Tom P

Zope page templates and query strings
by Stuart Robinson 17 Sep '02

17 Sep '02

Any advice on the following problem accepted with thanks: I'm generating a list of data items in a zope page template.The data comes from an ZSQL method and successfully generates a list of items in the database however I have Compilation failures if I try the following: <a href="delete?isbn="isbn"">delete</a> the error returned is " TAL.HTMLParser.HTMLParseError: EOF in middle of construct," What I'm trying to do is construct a query string thus (where isbn is '1234567890'): <a href="delete?isbn=1234567890>delete</a> The delete object (another page template) is (I hope) a tal equivalent to a '<dtml-call delete>' thanks in advance for any suggestions: Stu

by H. Christian Gromoll 17 Sep '02

17 Sep '02

Greetings. I was wondering if this is a bug, or if I'm just doing something wrong. I'm trying the following page template code: s is a list of strings. I'm trying to condition on membership of 'string' in the list s, but I get the following error: exceptions.TypeError on 'in ' requires character as left operand in "", at line 56, column 4 any help would be appreciated. regards, Christian Gromoll

Profiling python scripts on filesystem
by Hedley Roos 17 Sep '02

17 Sep '02

Hi all I want to profile my scripts on the filesystem, but unfortunately CallProfiler by Richard was not designed to do that, and I have no idea how to integrate Python's own Profiler with Zope. Any (not too hackish) ideas?

cross browser compatibility
by Mark McEahern 17 Sep '02

How do Zope folks negotiate the tension between supporting 4.x browsers and developing standards compliant websites? I'd be interested to hear any techniques, strategies, policies you've found helpful--also, if you have a perspective from which my question seems to embrace a false dichotomy, please share that too! Thanks, // mark -

Re: [Zope] Parametera and Formulator

This is calling a python-script like the following: python:form.listchains(CustomerCompany) CustomerCompany is a dtml-let in the main URL that called this Formulator Form. This is obviousely wrong as Zope complains that global name 'CustomerCompany' is not defined Mind you I am trying to learn Zope and Phyton at the same time here, so the solution/explanation is probably simple Thanks a lot for your kind response so far -- Dag Nygren email: dag(a)newtech.fi Oy Espoon NewTech Ab phone: +358 9 8024910 Träsktorpet 3 fax: +358 9 8024916 02360 ESBO Mobile: +358 400 426312 FINLAND

traversal problems
by Mario Bianchi 17 Sep '02

17 Sep '02

Hello, I have problems with traversal and the default Zope session data manager. My goal is to have many session data managers and a 'router' object that (when traversed) routes a user's web request to a new path that traverses the right session data manager (and thus makes it set the lazy object SESSION, if it is referenced in the original request). To achieve this, I wrote a SimpleItem class (called Prova for now) with a __bobo_traverse__ method that does nothing but returning an unrestrictedTraverse on the new path (which is the original one splitted in the middle and joined with the path that traverses the session data manager of interest). To make an example, let's say I put a bunch of session data managers each in a folder named /mySite/sdm#Folder. If the original request was: /mySite/folder1/prova/myDTMLMethod where myDTMLMethod sets the SESSION object, the Prova object (the router), when traversed, decides that session data manager #1 should handle this session, and returns: unrestrictedTraverse('/mySite/sdm1Folder/folder1/prova/myDTMLMethod') Unfortunately, this doesn't work: the SESSION object is not (lazily) appended to the REQUEST, but I can't figure out why. Also, I don't know if this is the right way of implementing the behaviour described above or should I use response.redirect() instead. I tried the first scheme by hand, as well, calling directly the URL /mySite/sdm1Folder/folder1/myDTMLMethod from a web browser and everything works fine: this time the SESSION object is created and appended to REQUEST. Thanks in advance for kindly helping, cheers, Mario. _________________________________________________________________ Send and receive Hotmail on your mobile device: http://mobile.msn.com

Checking variable types in Python Script
by Johan Carlsson [Torped] 17 Sep '02

17 Sep '02

Hi, How do I use type() in Python scripts. It seems that type() is restricted code (why?) is there any special replacement for type checking?
