No easy sure way at least. That is, if you have basic authentication (which is always the case when you have Zope out of the box). It's reported that in some cases http://user:password@yoursite.com:whateverport may log you out/log you in differently, but afaik that won't work in all browsers and all platforms _and_ it may present you with an authorization box Rik

Does it not work because they are DTMLMethods and not External Methods, or because I am returning the wrong values, or because of a proxy or security setting? The Methods are in the User Sources 'folder' and I am sure I chose "GUF" authentication from the list when I added the LoginManager.

The Great Python (and Perl) Method Renaming Poll
by Michel Pelletier 25 Oct '00

25 Oct '00

We will be conducting a community poll to decide what to call Python (Perl, insert your language here) Methods. Many candidates have been discussed, but I'm afraid I don't have enough time to cull all the candidates from the discussions. So, before the poll, we are calling for nominiations from the community. Please send me an email containing one or more candidate names. These names will be added to the list. No pre-screening will be done, so please exercise some discretion if your favorite name is more tounge-in-cheek than practical (you never know what the masses will decide though!). Later this week, I will create a web poll where you can vote for your favorite. thanks, -Michel

using a dictionary returned from an external method
by Matthew Wilbert 25 Oct '00

25 Oct '00

I have some DTML that needs to call an external method that returns a dictionary. I don't have any problem referencing the resulting dictionary by doing something like <dtml-var externalMethod()['key1']> <dtml-var externalMethod()['key2']> . . . However, I need to do this for several keys, and I don't want to call externalMethod several times. Is there a way to assign the method result to another variable, or is it possible that DTML is smart enough not to do the call multiple times? Or is there some other approach that I am not even thinking of? Any suggestions will be greatly appreciated.

Hi all, I am trying to follow the quick tutorial and immediately run into things I do not understand. I am trying to create a folder as explained in the docs. I get the error: Error Type: SuperCannotOwn Error Value: Objects cannot be owned by the superuser This is the example in which "Stan" needs to create a folder. Can anyone tell me what goes wrong and how to get it right? Cheers. J.J.

newbie inquiry about zope
by Aharon 24 Oct '00

24 Oct '00

I have just started looking at zope for the site I am developing. I was wondering if anyone could tell me whether it sounds like an appropriate tool to use. The basic idea of my site is to be a sort of multi-user-dimension for text. Meaning, we'll have various books available in a database, and people can log on and read a chapter or a whole book. The innovative part is that we will track which users are reading which texts, and let people interact with others reading the same text as them. We will also provide some other features, including user customization of fonts and colors, and the ability for users to write new texts to be included in the content library. People will be able to read, write, and discuss with each other. To enable serious literary analysis of diverse documents, we will have a number of text-parsing tools available to readers. One other important thing to mention is that we will have a lot of text in non-Latin character sets, including right to left languages. My questions are: 1) Could Zope help me keep track of who is reading what and match people up for discussion? 2) Could Zope help me personalize the fonts and other display settings for each user? How about letting users create their own bookmarks within the texts? 3) Could Zope help me manage user created content and the relations between content and its creators? 4) Could Zope handle right to left text and non-Latin character sets? 5) What are the advantages/disadvantages to developing this site with Zope as opposed to MySQL and PHP? 6) Could Zope help me make the same content available to ordinary web browsers and wireless devices in different formats? 7) Since we are going to be having discussion, we might want to stream voice between users and also stream pre-recorded voice. Any support for that? 8) Where can I find speed benchmark information about Zope? 9) Where can I find virtual server and collocation hosting for my site if I want to use zope, or do I have to administrate my own server? Any input about any of these questions would be greatly appreciated. I apologize for my ignorance. Thanks, Aharon

Modifiable local variables
by Sean McGrath 24 Oct '00

24 Oct '00

Hello all, I am trying to use the DTML engine outside of Zope, and would like to be able to create local variables in my DTML documents. Because I have no access to Zope, I can't do REQUEST.set, nor can I use the method shown on http://www.zope.org/Members/Duncan/LocalVars. So, the questions is, what is the recommended way to create modifiable variables using DTML, without using Zope? Thanks in advance
