How to programmatically return local roles?
by Dirksen 02 Feb '02

02 Feb '02

Hi, I'd like my object has a method that will return its local roles programmatically. Is there any hook in Zope for such purpose? Cheers Dirksen __________________________________________________ Do You Yahoo!? Great stuff seeking new owners in Yahoo! Auctions! http://auctions.yahoo.com

Image's modified-date changes just by viewing?
by Arian de Wit 02 Feb '02

02 Feb '02

Hi All, Either I am going completely insane or this is fairly obscure and I'm just going blind... I have some images in a folder, for which I use a "view" DTML method to display them inside a framework, calling them thusly: /folder/blah.gif/view The view method uses dtml-in to produce a list of links to other images in the same folder: <dtml-in expr="objectValues(['Image'])" sort="bobobase_modification_time()"> When I view an image using this method, the "Last Modified" date/time of that image is updated as a side-effect (or what I think is a side- effect). Can someone set me straight on this please? I must be doing something screwy, right?

ZSyncer patches for reverse sync?
by Terry Hancock 02 Feb '02

02 Feb '02

I've recently tried out ZSyncer, which seems to be pretty neat. It is missing one feature which would seem to be pretty nice, and I'm told there's a patch to do it, but not where I can find it. :) It'd be nice for some purposes to be able to pull objects from the "production" server to the "development" server (instead of the other way around) in Zsyncer. The author, Andy McKay, says there is a patch for this "somewhere", but I have done a number of searches at the Sourceforge site, on Google, and via Zope.org, ZopeZen etc, and can't find it -- so if someone knows where this is, it would be really nice to know. Thanks!

PUT_factory solution
by Adam Warner 02 Feb '02

02 Feb '02

Hi all, Thanks for the PUT_factory tip last night. I see this is a common issue with proposed solutions: http://www.zope.org/Wikis/DevSite/Proposals/ObjectTypeAssociationAndDeathTo… My initial solution is based upon a 12 October 2001 post by Andreas Wandel. My objective was to turn all text/* content into the content type file (NOT DTML content). And allow for DTML content to be uploaded using a .dtml suffix. You just create an external method named externalmethodname.py in the Extensions folder: def PUT_factory(self,name,typ,body): from OFS.Image import Image,File from OFS.DTMLDocument import DTMLDocument if typ[:6]=='image/': ob=Image(name,'',body,content_type=typ) elif name[-5:]=='.dtml': ob=DTMLDocument('',__name__=name) else: ob=File(name,'',body,content_type=typ) return ob import webdav.NullResource webdav.NullResource.NullResource._default_PUT_factory = PUT_factory And create a link to that External Method using the Zope management interface: ID externalmethodname Title Module Name externalmethodname Function Name PUT_factory I think I will also modify the external method so that anything I upload called 'index_html' is turned into dtml content by default. Thanks everyone. I misunderstood Chris' initial post as implying that this was only a cosmetic error message issue. A descriptive error message would have reduced the number of frustrating hours trying to work out what was wrong. Instead of the error message being "426 Error creating file" perhaps it could be: Zope tried to create a [insert DTML Document/DTML method/etc.] object. However your content could not be correctly parsed. Please investigate writing your own custom PUT_factory external method. By the way, if Zope was really smart it could automatically turn any text content that turns out to be illegal DTML into a text file type instead of rejecting the file. Regards, Adam

Yes, definitely. I do the same thing as you mentioned, only I do it for lawyers, not engineers. Your job will probably be easier (then again, it might not if the engineers want to tweak everything themselves). Ron > I have to integrate several smaller internal websites > into a larger intranet.

Is Zope Right?
by glearned 01 Feb '02

01 Feb '02

I have to integrate several smaller internal websites into a larger intranet. At the same time, I want to create a site that is easy to add content to. The primary users are several engineers, and I would like to set up a core structure that will easily allow me to add content in the form of white papers, downloadable powerpoint presentations with abstracts, FAQ's etc. without having to turn all of my engineers into html experts. >From the little I know, it sounds like Zope may be the ideal solution...am I on the right track?
