If you end up with 25 different contributors with the same sort of clause, you're going to have a complete shambles. Anthony

[patch] making 'Find' traverse into ZClass Products
by Anthony Baxter 21 Sep '01

21 Sep '01

I got completely fed up with the Zope 'Find' stuff not being about to traverse through Products/Foo/FooProduct, where FooProduct is a ZClass. The following patch adds this support to the FindSupport.ZopeFind method through the simple fix of saying "if it's a ZClass, keep looking in ob.propertysheets.methods" It seems to Work For Me - I'd post it to the collector, but I can't reach it at the moment...

re: Subclassing ZObjectManager in ZClasses

re: http://lists.zope.org/pipermail/zope-dev/2000-March/004034.html This message is about 1.5 years old, but no replies?, & I haven't seen any similar messages or howtos? --Alexandre Ratti Fri, 31 Mar 2000 >Summary: (when creating a folderish ZClass and cascading base classes) if >ZObjectManager isn't subclassed at 1st level, objects can be added to the >folderish ZClass instances but they don't show in the manage_main object list. >Here I first created MyBaseClass, then I subclassed it together with >ZObjectManager when creating MyTestClass ... >when I add objects in an instance of MyTestClass they do not show >in the object list (Content view). I *think* they are actually added >because I cannot add an additional one with the same ID: I get an "ID >already in use" error. >It's not that bad, but I can't create a standard base class, then use it to >create a folderish variant. I have the same symptoms, objects dont display in a folder subclass, but are there. Heres how I fixed it: Your base class must be the last in the class inheritance list. You must add all other base classes first. This will almost always be a problem because most base classes start with ZClass... and will be last alphabetically. (this will be much easier to fix if/when you can change, or at least reorder, the base classes of an object) eg: ZObject, ZObjectManager, CatalogAwareBase, MyBaseClass If you have a complicated object, I think you can export it in XML, reorder the base classes, & reimport. But adding/removing classes this way doesn't update the management interface tabs. Daniel Rogahn drogahn(a)d.umn.edu http://www.d.umn.edu/~drogahn/

Fwd: Re: [Zope-dev] WebDav Bug?
by Eric Brun 20 Sep '01

20 Sep '01

Hi, I'm working on webdav too. Question : When I access to my folder by webdav protocol (win98 webfolder), I can list the folder content, but when I want to access to a file inside, Zope asked to me another authentification, then I can access to my file (wordd file (.doc)) but only in read only mode. When I see the Z2.log, I see that anonymous user lock my file when I try to access it . Why ? Anybody for my question ?

Medusa Patch Lost
by Toby Dickenson 20 Sep '01

20 Sep '01

A zope-specific patch to medusa seems to have got accidentally lost between 2.3.x and 2.4. The patch below allows Zope to handle http requests as if it was a proxy, ie: GET http://servername/x/y/z HTTP/1.0 in addition to the more normal mode as if it was an origin server: GET /x/y/z HTTP/1.0 (there is an rfc for this, but I forget the number :-( (With the Collector down, I hope this is the best place for uncontroversial patches. Is anyone from DC looking out for them?) diff -c -r1.1.1.6 -r1.2 *** http_server.py 10 Sep 2001 14:55:08 -0000 1.1.1.6 --- http_server.py 20 Sep 2001 12:43:53 -0000 1.2 *************** *** 713,719 **** return m return '' !

Dreamweaver, Webdav and PUT.
by Terry Kerr 20 Sep '01

20 Sep '01

Hi, I am having trouble PUT'ing new files into Zope using webdav from dreamweaver. I have dreamweaver 4 with the 4.01 update, and are running zope2.4.1 with python 2.1. I have create a html file 'untitiled.html' and are trying to PUT that into the root folder of my Zope instance. I have setup webdav on port 8081, and authentication is setup correctly as I can GET, LOCK, UNLOCK and PUT files that already exist in the Zope tree, just not create a new file using PUT. >From looking at the zope logs, Dreamweaver seems to issue the following commands when creating the new file. "PROPFIND /untitled.html HTTP/1.1" 404 2305 "" "PROPFIND /untitled.html HTTP/1.1" 404 2305 "" "LOCK /untitled.html HTTP/1.1" 200 765 "" "PROPFIND /untitled.html HTTP/1.1" 404 2304 "" The LockNullResource object is created in the Zope root, however then dreamweaver spits out an error "The desired action could not be completed because the resource was not found". >From looking into the the lib/python/webdav/NullResource.py::LockNullResource code, it seems that calling PROPFIND on the LockNullResouce will always return not found! def HEAD(self, REQUEST, RESPONSE): """Retrieve resource information without a response message body.""" self.dav__init(REQUEST, RESPONSE) raise 'Not Found', 'The requested resource does not exist.' # Most methods return 404 (Not Found) for null resources. DELETE=OPTIONS=TRACE=PROPFIND=PROPPATCH=COPY=MOVE=HEAD It seems to me that you can never create a new file using webdav! Has anyone else come across this?

manage_pasteObjects and REQUEST
by Danny William Adair 19 Sep '01

19 Sep '01

Hi! Does anyone know when manage_PasteObjects will stop requiring REQUEST to be passed? I want to mimick the Cut/Copy/Paste Support of the management interface in a UI of my own. my method "objectsCut" holds: <dtml-call "manage_cutObjects(REQUEST['ids'], REQUEST)"> while my "objectsPaste" method holds: <dtml-call "manage_pasteObjects(_.None, REQUEST)"> Pasting objects will sometimes (!?!) redirect me to the management interface, which I want to hide. I found these last lines in manage_pasteObjects (CopySupport.py): def manage_pasteObjects(self, cb_copy_data=None, REQUEST=None): """Paste previously copied objects into the current object. If calling manage_pasteObjects from python code, pass the result of a previous call to manage_cutObjects or manage_copyObjects as the first argument.""" ... ... ... if REQUEST is not None: REQUEST['RESPONSE'].setCookie('__cp', 'deleted', path='%s' % cookie_path(REQUEST), expires='Wed, 31-Dec-97 23:59:59 GMT') REQUEST['__cp'] = None return self.manage_main(self, REQUEST, update_menu=1, cb_dataValid=0) I don't want to hack this file. The only way to get the cookie set seems to be passing the REQUEST object. "...pass the result of a previous call to manage_cutObjects or manage_copyObjects as the first argument" This doesn't help me very much. It would help me if I wanted to Copy/Paste or Cut/Paste at the same time: <dtml-call "REQUEST.set('my_clipboard_data', manage_cutObjects(REQUEST['ids'], REQUEST))"> <dtml-call "manage_pasteObjects(my_clipboard_data)"> works fine, but if I want to do Copy and Paste at completely different times, I have to pass my_clipboard_data along the requests all the time. Is there a simple solution? Is it something I should put in the Bug Collector? Or did I miss something? Thank you very much for your help, Danny

Operation Properties.

'Evening, Zopistas. I'm developing an accounting product right now, and one of the more interesting aspects of how to solve this issue is how do handle currencies. I've decided to let each entry (transaction) know about the currency it was in. At a later stage, the user is given the option to convert the currency to something else, but only for display-purposes and nothing persistent. This raises a number of interesting issues; I'll try to be brief. - I'd like the currency-attribute itself to know about how how display itself (ie. this shouldn't be a method of the class containing the property). - I'd like the currency-attribute itself to know how to convert itself to other currencies. This would allow me to say:: transaction.currency.set_amount_to(100.00) transaction.currency.set_currency('FRF') # French Francs And then this:: transaction.currency.display_in('NOK') # Norwegian kroners would render the string:: NOK 125.00 for example. Or:: transaction.currency.convert_to('NOK') would render the float:: 125.00 or something like that. I'm not entierly sure of the API, yet. The point is, I'd like to delegate attribute-behaviour to the attribute itself. Currently, I don't see any easy way to do this with Zope. I gather that there isn't either, based on the links I give below. It seems that many projects are implementing their own property-handling. Summarizing: I'd like to volunteer time to a project/proposal that would take care of properties once and for all. I'm proposing to create a new property model where we have "pluggable" properties that is more lously coupled with the management of properties and allows the developer to add custom-made properties (much like PlugginIndexes). I also propose to make the property itself know how to render a widget for it, given an environment. A property of type 'date', for example, could render six HTML select-lists given a HTML-environment (year, month, day, hour, minute (second, maybe), timezone). The functionality of these widgets should be a separated from the properties, naturally. It should also be pluggable. I'm thinking pluggable in a site-wide context here.
