Zope is a web application server. It allows you to write Javascript for client browsers just as you can using other such tools. It does not, however execute Javascript on the server. Server-side scripting is done using Python and less commonly nowadays, DTML. Templating of web pages is done using Zope page templates (ZPT) and DTML (an older templating language). You can certainly put javascript into pages using either templating system, but it will be executed on the client and not the server. hth, -Casey ALOK WHIG wrote: > Does it support Javascript ? > > > ----- Original Message ----- > From: Casey Duncan <casey(a)zope.com> > To: ALOK WHIG <awhig(a)del2.vsnl.net.in> > Cc: <zope(a)zope.org> > Sent: Thursday, April 11, 2002 9:56 PM > Subject: Re: [Zope] A query > > > >>Do you mean computer or human languages? >> >>If you mean computer languages then: >> >>Python natively >>Perl as an add on >> >>Zope iself is written largely in Python with low level bits coded in C. >> >>hth, >> >>Casey >> >>ALOK WHIG wrote: >> >>> >>> >>>Hello . >>> >>>I came across your product " Zope" and downloaded >>> >>>it win32 version .

[HELP] Use of "portal_metadata" in a DTML file
by flemaitre＠fede.generali.fr 22 Apr '02

22 Apr '02

Hello, I'm using the tool "portal_metadata" in order to fix a policy of metadata for my site. But i have a problem : - I'm making a DTML form wich allow my users to modify the Elements of the "portal_metadata" instance - In this DTML form, i get the list of metadata elements by using : "portal_metada.listElementSpecs()" ==> Ok - I want to access (and to modify) the detail of these elements by using : * portal_metadata.getElementSpec(element='My metadata').isRequired() * portal_metadata.getElementSpec(element='My metadata').isMultiValued() * etc.... ==> It doesn't work, Zope says "You are not authorized to access isMultiValued", but i'm "Manager" what does it mean ? From the ZMI, the form "metadataElementPolicies.dtml" (of CMFDefault) does the same thing, and it's work.... Why ? Thanks in advance. Excuse my english.... ;-) Fred.

Newbie: Synchronize document metadata?
by wojtek＠ifirma.pl 22 Apr '02

22 Apr '02

Hi, (Please, forgive me if my terminology won't be Zope-correct.) I am trying to build an information system with Zope but at the very begining I've run into the following problem: I have a group of MS Word users that are supposed to publish their work in Zope. They can handle Windows WebFolders (WebDAV), but they cannot and should not be forced to go into Zope management interface to tune the data they entered. I am supposed to create automatic navigation for the documents published this way. (Please, don't suggest emacs :-) I'd like the metadata stored in HTML and in ZODB to stay in sync. I mean <TITLE> in stored in HTML, but also other possible html <HEAD> content to be in sync with ZODB data. I know I could use DTML to display ZODB object title as html title, but this is not enough. 'In-sync' may not be the best word - in fact I would like to have only one instance of the title data :-) Has this problem been already solved? Is there a way to solve it? Thanks, Wojtek Narczynski

Content-Disposition
by Richard Wesley 22 Apr '02

22 Apr '02

I am not having any luck trying to download some script-generated text from a browser (IE5/Mac in this case). When I try the following in a python method: request.RESPONSE.setHeader('Content-Disposition', 'attachment; filename=file.txt') print 'Hello, filesystem!' return printed all that happens is that IE displays the text. Not very helpful.

Customizing administration pages in exUserFolder
by Per Hörnfeldt 22 Apr '02

22 Apr '02

Hi, we're building a product with user management and want to associate a number of properties and roles with the users. We would like to use exUserFolder but not use the management pages that comes with exUserFolder, but rather create our own pages that correspond to the layout for the rest of the product. Our pages shall not have any access to the Zope management interface. Has anyone an idea on how this is achieved in the best way?

Opening MSWord Document via WebDAV from <a href="..."/>
by Thomas Guettler 22 Apr '02

22 Apr '02

Hi! Is there a way to open a MSWord document via webdav from a link? It is unfortunately too difficult for most people to download the document from zope to a local directory, change it, and upload it again. Since Zope supports WebDAV it should be possible to open it via webdav by following a link (<a href="magic"/>) But what does "magic" need to look like? If I use magic=="http://zope-host:8080/foo.doc" "WebFolder" don't show up at drive letters. At least I didn't get it working. Since I need it for an intranet application it would be possible "mount" the webdav from zope to e.g. "z:" on all clients. Then a link to file:///Z|... should work. I heard that only Windows-XP is able to map webdav to UNC-Names An other solution would be to run a samba-server on linux which mounts the webdav. Someone on this list has reported that he got this working. But I don't like this. Would be nice if the server could be Windows, too. And I don't know if authentication works this way. According to http://www.zope.org/Documentation/Articles/WebDAV you need to use commercial products to map a webdav server to a drive letter (Webdrive, Teamdrive costing 39$ per client). Has someone experience with these products? Are there free alternatives which map a WebDAV-Server to a drive letter? Opening the word document with the windows explorer and editing is no problem. Has some hints? thomas

Folders with the same name (newbie question)
by Marie ROBICHON 22 Apr '02

22 Apr '02

First of all, thanks for your patience for reading this long post.......I posted it a while ago but had no replies so am trying again...... Our development site has approx the following structure: index_html - About | Guided Tour | Machine - Jobs - Beamlines - Machine | Parameters etc Inside each folder is a contents_html document. The index_html is at the root and displays this content under a generic banner with drop down menus (Javascript) with links to the top level folders and their subfolders. Local navigation is generated via a treemenu in each top level folder with the name attribute as the id of the top level folder, and which generates absolute_urls. However we get the following error when clicking a link in the treemenu, to http://mysite/About/GuidedTour Error Type: KeyError Error Value: Parameters Traceback (innermost last): File /zope/Zope-2.5.0-solaris-2.6-sparc/lib/python/ZPublisher/Publish.py, line 150, in publish_module File /zope/Zope-2.5.0-solaris-2.6-sparc/lib/python/ZPublisher/Publish.py, line 114, in publish File /zope/Zope-2.5.0-solaris-2.6-sparc/lib/python/Zope/__init__.py, line 158, in zpublisher_exception_hook (Object: GuidedTour) File /zope/Zope-2.5.0-solaris-2.6-sparc/lib/python/ZPublisher/Publish.py, line 98, in publish File /zope/Zope-2.5.0-solaris-2.6-sparc/lib/python/ZPublisher/mapply.py, line 88, in mapply (Object: index_html) File /zope/Zope-2.5.0-solaris-2.6-sparc/lib/python/ZPublisher/Publish.py, line 39, in call_object (Object: index_html) File /zope/Zope-2.5.0-solaris-2.6-sparc/lib/python/OFS/DTMLMethod.py, line 127, in __call__ (Object: index_html) File /zope/Zope-2.5.0-solaris-2.6-sparc/lib/python/DocumentTemplate/DT_String.py, line 473, in __call__ (Object: index_html) File /zope/Zope-2.5.0-solaris-2.6-sparc/lib/python/OFS/DTMLMethod.py, line 120, in __call__ (Object: javascript) File /zope/Zope-2.5.0-solaris-2.6-sparc/lib/python/DocumentTemplate/DT_String.py, line 473, in __call__ (Object: javascript) File /zope/Zope-2.5.0-solaris-2.6-sparc/lib/python/DocumentTemplate/DT_With.py, line 76, in render (Object: Machine) File /zope/Zope-2.5.0-solaris-2.6-sparc/lib/python/DocumentTemplate/DT_With.py, line 60, in render (Object: Parameters) KeyError: (see above) I presume that Zope moves up to the root to pick up the index_html then moves back down until it finds the first "Machine" folder, which is not the one we want then raises an error. Does this mean that in Zope no two folders can have the same id? This would cause problems when our contributors edit their parts of our site. Is there a way around this other than naming the folders differently? TIA Marie Robichon Web Task Force European Synchrotron Radiation Facility Grenoble France

DCWorkflow -worklists, expressions, roles -- is this a bug?
by Heimo Laukkanen 22 Apr '02

22 Apr '02

Hi, I was playing around with DCWorkflows worklists and wondered how the expressions work. I thought about the possibility to give owners the 'Review portal content'-permission in Members-folders. In worklists I first set the permission, but that did not work. Actions from transitions did come visible, but not this new worklist. New worklist came visible for manager-users though! I tried the same with expression: python: here.portal_membership.checkPermission('Review portal content', here) And same happened. Manager or everyone else, who had the Review portal content set in the portal root, saw this ned worklist. No one else. This raises question that are transitions' and workflows expressions evaluated in different contexts- or what migth cause this? Zope 2.5.0, DCWOrkflow 0.4 , CMF 1.3 b -huima
