I can't understand why. More general, I'd like to extract all the variables available in a namespace (and if I can do it, I'll can get the list of the fields). Best regards, EB.

determining Owner of an object?
by Darran Edmundson 24 Mar '00

24 Mar '00

A simple question, how can I determine the Owner of a ZClass instance (or any Zope object for that matter)? My users create instances of a Seminar ZClass. I did not create a SubmittedBy property (which I would fill from AUTHENTICATED_USER.getUserName()) thinking that I could easily extract this from the Owner role. I just can't see how to do it. Cheers, Darran.

Check to see if someone is a user, or anonymous
by Baker, Dennis (sjmr) 24 Mar '00

what is the easiest way to find out if someone has logged in? I want to print some content on a page and have found a way to tie content to roles, but not to print only for anonymous users.

within the context of an object this might help you: "AUTHENTICATED_USER.has_role('Owner',this())" cb -----Oorspronkelijk bericht----- Van: Chris Withers <chrisw(a)nipltd.com> Aan: Jonothan Farr <jfarr(a)real.com> CC: Zope Mailing List <zope(a)zope.org> Datum: vrijdag 24 maart 2000 11:15 Onderwerp: Re: [Zope] determining Owner of an object? >> <dtml-in get_local_roles> > >I tried sticking <dtml-var get_local_roles> in a dtml document and got a blank list back even though >I know I've got some local roles. > >Also, where did you find out about this?

ZCatalog and XMLDocument problem
by Chris Gray 24 Mar '00

24 Mar '00

This has to do with Amos's article on using XMLDocument at xml.com: http://www.xml.com/pub/1999/12/zope/index.html The example for finding items to catalog doesn't work for me. When I enter getNodeName()=='entry' in the 'expr' field I get the following error: Error Type: NameError Error Value: Eval I'm running Debian GNU/Linux (frozen), Zope 2.1.4, Zcatalog 1.0.0 and XMLDocument 1.0a5. Thanks for any help you can give me on this one. Chris Gray University of Waterloo

how to get the fields returned SQL method
by Eric BARROCA 24 Mar '00

24 Mar '00

Hello, I'm trying to get a list of fields returned by a dynamic SQL query. I've found a howto telling me to write something like : <dtml-in SQL.names> <dtml-var sequence-item> </dtml-in> But it doesn't work : I get the error "Attribute Error : names". I've tried with .items, .keys and .fields too. I'd like to do the same for an LDAP query. Any idea ? I think it's very useful and that an easy way exists but I can't find it. Thanks, EB.

Re: [Zope-dev] Re: [ZIP] dtml-var syntax revisited
by Stephan Richter 24 Mar '00

24 Mar '00

I think a translator should implemented using a flag in dtml-var: syntax: <dtml-var VARIABLE translate> and <dtml-var VARIABLE translate="de"> for example. Short form: &dtml.translate-VARIABLE; By default it chooses the root folder's (or even Zope's?) language setting, but the programmer can also choose the language. This syntax is very similar to the "missing" flag. This way you do not a separate phrasebook and word translator. All that is in the background.... Then there is a generic translate product which handles all the translation stuff and administrates the languages. One can easily drop languages into the product, by installing simply the dictionary for this language into some standard location and specifying some admin info. I think that would be the cleanest way to implement ZIP. What do you guys think? Comments?

Zope hanging: internal ZODB error?
by Darran Edmundson 24 Mar '00

24 Mar '00

I recently took the site I have been developing online and have been beta testing with several users. I have a problem which is preventing a user from viewing his home page; any attempt I make to isolate the problem hangs Zope, stops anyone accessing my site, and requires a forced unix kill. The user's page is: http://rsphysse.anu.edu.au/optics/people/jdl124 Users are implemented as a Person ZClass. One of their contained objects is a PublicationFolder ZClass, itself a container class for Journal ZClass instances. So above: optics (folder) people (folder) jdl124 (Person) publications (PublicationFolder) article1 (Journal) article2 (Journal) . . article69 (Journal) jdl124's home page is dying when it tries to iterate over the results from a search of the ZCatalog publicationCatalog.
