A small note on security assertions
by vio 14 Jan '02

14 Jan '02

If you are like me and don't like to start coding from scratch, but rather like to start modifying an existing and proven source skeleton, like the Boring product for example, one small piece of advice: watch out for conflicting declarations. It took me over one month (give or take) to find out why all my security assertions (such as 'security.declareObjectPublic()' and such) were totally ineffective: because I left '__ac_permissions__' skeleton code hanging. Once that was commented out, all worked finally as advertized. Still, a month of wasted search, running like a headless chicken through sources and docs. Painful and frustrating. I hope this little note might save someone similar frustration. Because Zope is really, really great. Cheers, Vio

DTML into Python for Formulator
by cgreen 14 Jan '02

14 Jan '02

Okay... I'll admit it: I'm one of those who only knows about Python because of Zope. I am working with Formulator, and need a method to return a list of properties. I have DTML code that returns the list <dtml-call "REQUEST.set('tmp',{})"> <dtml-in expr="_.sequence.sort(PARENTS[0].objectValues(['STX_Document']), (('topic', 'nocase'), ('title', 'cmp'),) )"> <dtml-call "REQUEST['tmp'].update({topic:''})"> </dtml-in> <dtml-in "REQUEST['tmp'].keys()"> <dtml-var sequence-item> </dtml-in> The values of the "topic" property are returned. But when called as an override method for a Formulator MultiListField, I get this error: Zope Error Zope has encountered an error while publishing this resource. Error Type: NameError Error Value: global name 'REQUEST' is not defined File /usr/local/Zope/lib/python/DocumentTemplate/DT_Util.py, line 231, in eval (Object: form.topic.render()) (Info: form) File <string>, line 2, in f (Object: guarded_getattr) File /usr/local/Zope/lib/python/Products/Formulator/Field.py, line 178, in render (Object: topic) File /usr/local/Zope/lib/python/Products/Formulator/Field.py, line 156, in _render_helper (Object: topic) File /usr/local/Zope/lib/python/Products/Formulator/Widget.py, line 451, in render File /usr/local/Zope/lib/python/Products/Formulator/Widget.py, line 376, in render_items File /usr/local/Zope/lib/python/Products/Formulator/Field.py, line 107, in get_value (Object: topic) File /usr/local/Zope/lib/python/Products/Formulator/MethodField.py, line 40, in __call__ File /usr/local/Zope-2.4.3-linux2-x86/lib/python/OFS/DTMLMethod.py, line 192, in __call__ (Object: topics) File /usr/local/Zope-2.4.3-linux2-x86/lib/python/DocumentTemplate/DT_String.py, line 546, in __call__ (Object: topics) File /usr/local/Zope/lib/python/DocumentTemplate/DT_Util.py, line 231, in eval (Object: REQUEST.set('tmp',{})) (Info: REQUEST) File <string>, line 2, in f (Object: guarded_getattr) NameError: (see above) Okay -- I can figure out that it's because there's environment (namespace stuff) when DTML is called as a method that just doesn't work. So it needs to be rewritten as a Python script, but I'm a Python neophyte, so I'm asking (pleading.... begging....) for help. Thanx in advance

Calling every zoper, newbies to gurus
by seb bacon 14 Jan '02

First, apologies for the cross posting. I need to make sure this gets to as many people as possible, for obvious reasons... Everyone's got grumbles about how zope.org is organised. Now is the time to quit grumbling and do something about it. If you are a newbie or a guru, please take the time to respond to this email! I'm currently in the process of defining requirements for improving the zope.org website. The first part of this process is listening to the key constituencies for the site. Please note, I'm *not* planning on making a new products rating system, or a replacement for the fishbowl: I'm interested in the graphical design and informational content of the site. The questions are intended to help me understand who is using zope.org, how they use it, and what they would like it to be. If you don't want to answer all the questions, that's fine - just one answer is better than none. Reply to this email privately. I won't divulge any of the information to anyone else for any reasons, and the information will only be used to help improve the zope.org website. I will write up a report once I've received enough input, and publish the results online. Thanks for taking the time to help improve the web site... seb -=-=-=-=-=- 1) How did you hear about Zope? 2) Before you used Zope, what were you expecting? 3) How did the zope.org website change this?

access cvsweb thru Zope
by Max Ischenko 14 Jan '02

14 Jan '02

Hi, I'm trying to find a way to use perl cvsweb CGI script via Zope. The main reason for this - use powerful auth means that Zope has. Our CVS repository is partitioned on project basis using standard UNIX mechanism (owner/group/perm). So I can't simply run cvsweb from anonymous user --- it won't has required permissions. I (probably) need to auth user first (thru Zope) and then run cvsweb.cgi from that user. Does anyone do something similar? Is it possible at all? AFAIU I should grok External Method first. -- Rgrds, Max Ischenko
