ANN: i18n effort after the sprint
by Juan David Ibáñez Palomar 22 Jan '02

22 Jan '02

Hi all, As probably you already know, the last week there was a sprint in Fredericksburg to put internationalization support in Zope 3. A summary of the sprint can be found in: http://dev.zope.org/Wikis/DevSite/Projects/ComponentArchitecture/Feb2002Int… To coordinate this effort a new wiki page has been created: http://dev.zope.org/Wikis/DevSite/Projects/ComponentArchitecture/Zope3Inter… Besides the wiki the mailing lists will be used for discussion. Specifically the mailing lists "zip" and "zope3-dev" seem to be the ones that better fit. The effort is going to be splitted in several subprojects (text encoding, language negotiation, page templates extensions, etc..). The sprinters are working on the specific proposals for every topic, as they're ready they'll be put on the wiki and announced in the mailing lists. There's already a proposal to address the text encoding, Andreas Jung will coordinate this subproject (at least at the beginning), the proposal is at: http://dev.zope.org/Wikis/DevSite/Projects/ComponentArchitecture/UnicodeOrU… Please, add your comments to the wiki. There're also a couple of proposals to extend ZPT: http://dev.zope.org/Wikis/DevSite/Projects/ComponentArchitecture/ZPTInterna… http://dev.zope.org/Wikis/DevSite/Projects/ComponentArchitecture/ZPTi18nAlt… Please use the wikis to comment on each specific proposal, and/or write your own. I think the "zpt" mailing list will be the best one to discuss this topic. We want more people to get involved in this effort. If you want to help in the implementation or coordination of any topic send me an email and I'll help you as much as posible. At the first stages I'll coordinate the discussions and help people that wants to lead any subproject, until each one has somebody that takes care of it. Cheers.

PROPOSAL: Catalog Index Query Sets
by Casey Duncan 22 Jan '02

22 Jan '02

I have drafted a new proposal to fix, hopefully once and for all the query-side limitations of ZCatalog. http://dev.zope.org/Wikis/DevSite/Proposals/IndexQuerySet I considered just creating another product that does this, but I felt like it needed to be in the core to achieve maximum usefulness. Please comment. If it receives a positive response, I will implement it. /---------------------------------------------------\ Casey Duncan, Sr. Web Developer National Legal Aid and Defender Association c.duncan(a)nlada.org \---------------------------------------------------/

Fat client thoughts, was: RE: [Zope] Zope + XML-RPC + native GUI
by Jon Edwards 22 Jan '02

> No, I haven't done this, but I plan to do something like this to create a > fat client to interact with content objects in a CMF site I am building. > I've been playing around with wxPython and Boa Constructor > (http://boa-constructor.sourceforge.net) I'd be interest in finding out > ways in which other people might be creating apps using these tools. <lots of good stuff snipped> Hi Sean I don't know if you've seen PythonCard? ...newish GUI building app for wxPython (a bit like Boa, but "lighter") - http://pythoncard.sourceforge.net/ On their mailinglist, they're discussing which DB to use as a (built-in) persistent storage, and ZODB is one of the options - http://www.geocrawler.com/lists/3/SourceForge/14884/0/7610885/ One of the samples that comes with Pythoncard is "textRouter" (also at http://simon.kittle.info/textrouter) which is a wxPython client that uses XML-RPC to post to Blogger or Manilla sites via their APIs. Looks like it could give you a headstart in developing your CMF-GUI? (If you're looking for collaborators, I'd be keen to get involved!) (BTW has anyone implemented the Blogger API - http://plant.blogger.com/api/index.html - in Zope/CMF? I'm planning to try it soon, so if anyone has any tips/code they wouldn't mind sharing, I'd be very grateful! :-) On a slight tangent, I also spotted a wxPython app called Gimini - http://gimini.sourceforge.net/ It's officially a "MindMapping" tool, but I thought the GUI could be adapted to make a nice drag-n-droppable sitemap tool for CMF, a bit like the one in FrontPage! :-) Hope that's helpful!

2.5.0b4: how to deadlock/DoS your Data.fs
by Pierre Fortin 22 Jan '02

22 Jan '02

Hi, I've been away from Zope for nearly two years and thought I'd give 2.5.0b4 a whirl... instead, it's giving me a spinning head... I have multiple sites and would like to give Zope another try... When I first go into Zope at localhost:8080/manage, the first thing I tried was to add a VirtualHostMonster (specifying all the fields)... Big mistake #1... the Data.fs is toast -- no way to access it... Re-install and try again... This time, I try SiteRoot, specifying the fields: pfortin.com http://pfortin.com/ /Z Big mistake #2! Re-install and try again... This time, I do the same thing; but without specifying a Base... Big mistake #3! In every case, I was left with an unusable Data.fs because the http://localhost:8080/manage page was now pointing to non-existent data... I'm off to do some more reading; but the intent was to try to setup 2 virtual hosts on localhost:8080 without disturbing the running hosts on port 80... but I ended up with deadlocked files since main screen points to http://localhost:8080/<fubar>/manage* which are not setup.

New Medical/Healthcare Python/Zope user group - Zopymed
by Jon Edwards 22 Jan '02

22 Jan '02

>From an idea on the Openhealth mailing list, we've setup a new user-group for Zope/Python users involved in the Medical/Healthcare fields (and surrounding fields, such as Education, Research, BioInformatics) ...or ZoPyMed for short! Just a mailing list so far - http://maillist.linuxmednews.org/mailman/listinfo/zopymed - but we can setup an associated website if there is sufficient interest. Short-term, the list is a place to ask questions and share ideas, code, tips and useful-links. Long-term, we might aim to create reusable components/functionality and promote interoperability between different applications. But the "agenda" is very fluid, and open to suggestions! So, if you're using Zope/Python and are involved in Medical/Health-related IT, please join up, introduce yourself, and tell us what you'd like to see from this group! Cheers, Jon Jon Edwards Pricom Ltd www.pricom.co.uk

Zope 2.4.4, when?
by Leonardo Rochael Almeida 21 Jan '02

21 Jan '02

Guys, please, We really need 2.4.4 and our client won't accept a CVS version. 2.5 betas won't do it either. What is holding 2.4.4 back? Is there anything you need help with? testing? bugfix? Cheers, Leo -- Ideas don't stay in some minds very long because they don't like solitary confinement.

REQUEST.AUTHENTICATED_USER question
by vio 21 Jan '02

21 Jan '02

Hi, Does anybody know what is the method call to modify the AUTHENTICATED_USER attribute? I am unable to trace where REQUEST feeds data for its AUTHENTICATED_USER attribute. Some context to my question: I am using a custom method to authenticate users coming to my site. So when the user logs in, he is 'Anonymous User' (from call: AUTHENTICATED_USER.getUserName()). But after his login name and password checked ok, how do I switch his identity in Zope from 'Anonymous User' to his/her new identity? What I am looking for is that next time I call 'REQUEST.AUTHENTICATED_USER.getUserName()' to get the new UserName he just logged in as, not 'Anonymous User' again. Examining CookieCrumbler.py source, this authentication product uses the 'before_publishing_traverse hook' mechanism. But isn't there a simpler way to do this than modifying REQUEST.RESPONSE at each traversal? Sounds like a lot of overhead. Vio
