No - the current incarnation of WebFolders (Microsoft's product) does not deal with locking. Office 2K does (it locks a document while editing it). Zope currently "fakes" locking support as an unofficial measure to allow folks to open O2K docs stored in Zope. We faked it partly because there was (even fairly recently) some disagreement in the DAV group about how locking ultimately should work, and partly because DAV clients haven't exactly taken the world by storm at this point and that has to be reflected in our priorities. Note that even if locking were supported on the Zope side, I don't think that this would help your situation since WF will not lock an object just because you dragged it to your local desktop. AFAIK, O2K will only lock something if you open it directly with O2K. Brian Lloyd brian(a)digicool.com Software Engineer 540.371.6909 Digital Creations http://www.digicool.com

Site Powered by Zope
by Andrew Kenneth Milton 31 May '00

Hrm I just went to applixware.com to look for updates for Applixware (UNIX Office suite), and they've become VistaSource.com. Down the bottom of their site is the venerable "Powered By Zope" icon. I knew they'd started a new Open Source development plan, but, its still good to see large-ish sites running Zope. -- Totally Holistic Enterprises Internet| P:+61 7 3870 0066 | Andrew Milton The Internet (Aust) Pty Ltd | F:+61 7 3870 4477 | ACN: 082 081 472 | M:+61 416 022 411 | Carpe Daemon PO Box 837 Indooroopilly QLD 4068 |akm(a)theinternet.com.au|

dtml-tree again... : ugly look w/Netscape
by Pierre-Julien Grizel 31 May '00

31 May '00

Hi again, I don't know if some of you have noticed the dtml-tree looks sometimes bad with Netscape : the item text is too far frow the +/- signs, like this : CORRECT : root + abc + def - ghi - jkl BAD W/NETSCAPE 4 : root + abc + def - ghi - jkl Well, I've just forgotten to say in my previous posting that the <dtml-tree query_expr=...> patch also corrects this problem. See http://www.en.xlogx.org/Zope and enjoy (download and better (?) explanation). P.-J.

object.... from name
by Pierre Rougier 31 May '00

31 May '00

Hi all... well, I think this is a quite simple problem.... In a method, I want to apply an external method to a ZObject stored in the Folder: <dtml-var "CreeDetailBiblio(Special object)"> the fact is that I have the object name through the Query_string, so I tried: <dtml-var "CreeDetailBiblio(QUERY_STRING)"> which does not work.... that is clear.... as this is a string, and not my object itself how can I can find the object itself, to use it as an argument of my fonction, from its name, which is stored in the query string? I think this is very simple..... but I don't find the documentation.... Thanks for your attention

'or' queries in ZCatalogs? (and a general design question)
by Howard Jones 31 May '00

31 May '00

I am currently working on a toy zope project for myself, which is a historical database of sorts (it's an On The Day In History type of thing - today.thingy.com is the current version, which is somewhat broken right now). What I wanted to do was be able to 'surf' events - have them linked by the people involved, the timing of them, or some general theme, in a similar way to wikiwebs (more like imdb really). So far, I have a TodayPageItem ZClass, with some basic information (the body text, the date of the event) and a couple of 'Lines' type properties called People and Threads. In the index_html for presenting an event object, I use: <dtml-if "threads[0] != ''"> <dtml-in threads> <dtml-in "Catalog(meta_type='Today Page Item',threads=_['sequence-item'])"> <dtml-if sequence-first> <h4>Threads</h4> <ul> </dtml-if> <dtml-unless "Catalog.getobject(data_record_id_).id == PARENTS[0].id"> <li><a href="<dtml-var TodayBase><dtml-var "Catalog.getpath(data_record_id_)">"><dtml-var title></a> </dtml-unless> <dtml-if sequence-last> </ul> </dtml-if> </dtml-in> </dtml-in threads> </dtml-if> To show the related objects in the same threads as this one (objects may involve more than one thread - Inventions, and Government, for the found of the US Patent Office, for example). However, I then have a similar piece of DTML directly below it to do the same for the People list. Can I combine these? I would like to show one link only for each related object, even if it related more than one way, and also to show how they are related next to the link. According to the Advanced ZCatalog howto, the only way of doing this loads the whole lot into memory - I plan to have thousands of these! Is there some magic I'm missing? Thanks in advance for any advice (don't do it this way?), Best Regards, Howard

But remember when you are asking for DateTime object equivilancy you must be exact. Time Zone and all. What you have outlined seems like it should work, but it is less flexible. What happens when someone's appointment spans two days? Can you easily determine how long an appointment will last and figure out if there is anough time available to accomodate it? With two DateTime objects those things are quite easy. With strings it requires a lot of maipulation. Hope I haven't confused you further. ;) Jason Spisak CIO HireTechs.com 6151 West Century Boulevard Suite 900 Los Angeles, CA 90045 P. 310.665.3444 F. 310.665.3544 Under US Code Title 47, Sec.227(b)(1)(C), Sec.227(a)(2)(B) This email address may not be added to any commercial mail list with out my permission.

I can't edit anything that has already been uploaded so I have to� keep a local copy of everything. What can happen is that someone else updates� a page from their local copy then I update from mine and lose the changes. �� The idea with WebDAV was that I could lock edit and unlock with the only copy being in the Zope database. -- Graham ------------------------------------------------------------------------------- Beware of Geeks bearing GIFS. http://www.jlab.org/coda Jefferson lab DAQ group
