Yes, that's what i would have thought . I'll move this to the
Plone users list - there may be some specific Plone evil involved,
though I don't see how.
Thanks for the input.

[Zope] Existence and truth
[profound subject: sorry the body may be less interesting]
This is so basic, but any help would be appreciated. It's also a Plone
site, but the problem is about basic tal behaviour so I hope it's
appropriate:
I have an attribute, 'listed' (a property of 'member') which I want the
user to be able to set or unset with a radio choice rather than by
checking or unchecking a checkbox, as provided in default join_form and
personalize_form.
In personalize_form, I define listed like this:
listed python:request.get('listed', member.getProperty('listed',''))
The radio inputs return name="listed" and value 0 or 1
This works OK, but in the radio input code,
tal:attributes="checked python:test(listed,'checked',None);
*always* returns 'checked'
and the second of these debug lines is *always* displayed, whether
listed is 0 or 1:
debug: value of listed, after define with getProperty=tal:content="listed">value
debug: this para should print if
listed is true, ie equals 1
Appendix C of the Zope Book says tal:condition tests for existence and
truth, and "missing variables, None, zero, empty strings, and empty
sequences false; all other values are true".
So what basic fact/knowledge am I missing?
Thanks

The reason: Zope usually expects to work with acquisition wrapped objects. "aq_base" discards the acquisition context. You should carefully examine the context of the code fragment above.

Re: [Zope] making a dynamic quiz help
- Original Message - From: "Thomas Bennett" <[EMAIL PROTECTED]> To: Sent: Tuesday, November 28, 2006 1:40 PM Subject: [Zope] making a dynamic quiz help I would like some suggestions on building a dynamic quiz. There are categories and in each category the question can be multiple choice or true/false. For each category a specific number of questions is asked. The questions asked are randomly chosen from a collection of questions for the category. The number of questions chosen may be different for each category. example category one - 3 questions category two - 1 question category three - 2 questions My first thought is a python script does the randomization selecting questions from my postgresql database. Quizzes submitted updates the database counting correct and wrong answers and emails the results to the student and instructors. A second thought is a python script builds a dtml page quiz from individual dtml files which categories can be folders with an individual dtml file for each question. Then submit questions and answers to database and email student and instructors. A third thought is create a collection of complete quizzes and then randomly select a quiz (least preferred). I've searched and the closest I could find was on the zope edu wiki just discussing an aggregated quiz but I haven't found where that has been persued. Most or all quiz products create static quizzes not one that can be built "on the fly". Any other designs would be appreciated. If I was building this app I would have a dtml method (or ZPT, whatever you are most comfortable with) that invokes a python script (or external method) to provide data for the dtml/zpt form fields. A second dtml method/zpt would be used as the form processor, it would invoke a python script/external method to process the form data input by the user (update db, send email, whatever) and then display some confirmation/thank you message to the user. Pretty straightforward app. Have fun!
