This is sort of how Versions (for those of you using 1.10.x or lower, we've changed Sessions to Versions to clear up the namespace for "real" sessions) work. When you create a Version, it puts you in your own little work area that looks exactly like the publicly visible area does. Now, you can edit the Versions, break it, change it completely, and it won't show up until you save the sessions. I agree that *I* would feel more comfortable if the terminology were more RCS/CVS (check out, check in, add, remove, commit) but would everyone else? This would require a proposal from the community. -Michel > > Anything in the works on this front? > > ------- > Jordan B.

Unfortunatley, due to some lameosities in Netscape's Composer it's not great either. We are in the early stages of supporting WebDAV. WebDAV will, with any luck, allow you to use any WebDAV-compliant client to interact with simple Zope items. You can check out Zope's WebDAV support by downloading IE5 and asking Brian Lloyd (brian(a)digicool.com) to give you a demo account on the webdav.zope.org server. We had an internal class on this yesterday and it looks quite cool. ALternatively, you could check out the early versions of ZServer with which you can use arbitrary FTP clients. Again, this supposes that your content is largely static and that you won't need to render DTML tags during the development of the content. <!--#var My$0.02> --Rob

help! uploading images..
by julian＠zereau.net 01 Apr '99

01 Apr '99

I need to let customers 1) upload a replacement for an image that already exists in the zope tree 2) upload a new image which was not already in the zope tree, and add it to the "images" folder How can I do this? I do not want to simply give the customer write-access to the images folder as this would be both too complex for them, and too insecure. I would prefer to be able to do this from within a form of my own making. --- Julian Morrison Programmer (Zereau Ltd)

using 'tree' from a 'lines' property.
by Tony McDonald 01 Apr '99

01 Apr '99

Hi all, I'd like to be able to use #tree to create a table of contents of the following form, but as I'm not massively familiar with #trees yet, I'd like to know what I'm letting myself in for... If I have a property, type 'lines', called ToC which is like Guide, 1, 101 Cell Biology, 1, 102 Introduction, 2, 216 Item 1, 3, 301 Item 2, 3, 330 ... Topic #1, 2, 400 (ie each line is composed of a description, the 'level' at which the description should occur, and a unique identifier for that description) can I use DTML to create a #tree structure of the following form; Guide Cell Biology Introduction Item 1 item 2 ... item n Overview item 1 .. item n Topic #1 ... where each line above is a URL (something like<a href= http://host/get_items/400/disp_items>Topic #1</a>) or do I need to start writing an external method? any thoughts appreciated. tone ------ Dr Tony McDonald, FMCC, Networked Learning Environments Project The Medical School, Newcastle University Tel: +44 191 222 5888 Fingerprint: 3450 876D FA41 B926 D3DD F8C3 F2D0 C3B9 8B38 18A2

ZTemplates without Zope
by Oleg Broytmann 01 Apr '99

01 Apr '99

Hello! I am trying to rewrite some of my CGIs using ZTemplates, no Zope yet. I want to clarify some points I do not understand clear. Any help welcome. Think I will write a DTML file, and there is the tag  As far as I understand, there is no way for DTML to place standard_html_header into a file - aquiring and rendering IDs is a job of Zope, not ZTemplates, right? What method I can use? Do I need to create few instances of DocumentTemplate.HTMLfile and call them with different files/objects? Any simpler way?

RE: [Zope] DTML question

I was just having a problem with this myself and this solution worked like a charm. Thank you! I'm still left with a question, though: How would you go about using sequence-item, etc. in a python expression? Python sees it as 'sequence minus item' and I get a 'Name Error: sequence' exception. I was wanting to do something like this: <table>  <tr> <td></tr> <td></td> </tr>  </table> Which seems natural to me but, of course, doesn't work. I have the feeling that I might need this in something like Ouch! someday. I've read the DTML manual several times but have I missed something here? ??? Again, Thank You!

I seem to remember that if python sends something to stderr, then this will happen. Try cd'ing to [Zopedir]/lib/python and run python, then 'import Main'. At this point, if it fails, there is something wrong with your Zope install, or maybe an extension didn't compile right, etc... If your using Linux, have you considered using Zap? http://www.zope.org/Download/Zap-1.1.0 even if you don't want to use our precompiled 1.3.4 Apache, or you aren't running Linux, it is still handy to eyeball the .conf file we used. -Michel > TIA, > Daren > > > _______________________________________________ > Zope maillist - Zope(a)zope.org > http://www.zope.org/mailman/listinfo/zope > > (For developer-specific issues, use the companion list, > zope-dev(a)zope.org - http://www.zope.org/mailman/listinfo/zope-dev ) >

You may very well be correct. This problem has never been reported however, and your the first user of this server software we know of. That's how I came to the conclusion that it might be the plugin. > Well, I am a contractor and really don't have that option.

Try using your trick of modifying the URL to add a DTML method, then try and edit that method putting:  into it. I'm curious about some of the values that the server passes into Zope. If you can't add a DTML document because of this bug, you can use this supreme piece of trickery: First, shut down Zope, then cd to the [Zopedir]/lib/python directory. Then: [michel@aldous python]$ echo '' > test.dtml [michel@aldous python]$ python Python 1.5.1 (#2, Jan 26 1999, 10:47:10) [GCC 2.7.2.3] on linux2 Copyright 1991-1995 Stichting Mathematisch Centrum, Amsterdam >>> f = open('test.dtml') >>> file = f.read() >>> import Main >>> Main.app.manage_addDocument('test', 'This is the title', file) '' >>> get_transaction().commit() >>> manage_addDocument's first argument is the document method's id that you wish to add. Then, go to http://x.y.z/.../test This will show you the REQUEST object. Optionaly if this is too dificult, you can try and make a cgi script which prints out it's environment that the server creates for the script. This might not reproduce the problem if it's nscgiauth's fault, but if it isn't, we might see something in the cgi process environment. -Michel
