- Using "tree" with an object
by Gabe Wachob 19 Jan '99

19 Jan '99

OK, another question. I have an XMLFile (derived from Document). It has a domtree attribute which contains the XML document as a DOM tree. I have a index_html.dtml file which is displayed as the default view. I would like to use the  construct to interactively view the XML files (as trees), hiding and displaying structure as the user pleases. I was going to do this by hand, but I thought using the  construct would be kewl. Well, I'm having more problems with DTML. How do I use the  construct with the object's domtree attribute (that is, with any object referred to by my Document-subclasses XMLFile)? I've tried just inserting "domtree" in the name attribute (no success) of tree, I tried "self.domtree" (no success), I've tried "_.getitem(document_id, 0).domtree" (no success), I've tried the below (no success):    I really don't know what I'm doing -- the documentation on how to refer to objects contained within a Document (for example) in the context of DTML seems incomplete. Finally, how do I write my own HTML response forms? Do I *have* to use MessageDialog? Also, where are MessageDialogs documented?? If I don't have a REQUEST or RESPONSE as an explicit parameter to my methods, what does ZPublisher do with the stuff returned by a published method? Am I asking too much for all this documentation? -Gabe

PCGI info files will override environment variables, a feature which has a potential for misuse. The pcgifile sanity checker will issue a warning to the unwary.

I don't and I'm quite sorry about it. The docs are essentially done but they won't get online this week. It's hard, we are all pretty freaking busy around here right now :^( > Hey, I'm with ya there.

The easiest way to influence our prioritization of things is through consulting contracts or other arrangements that allow us to rearrange projects. > I'm more than willing to help out on this Zopespot project! > I'd be even > more motivated if I could get something out of it soon ;-) Hey, I'm with ya on that one, brother!

- A little problem...
by Magnus Lie Hetland 19 Jan '99

19 Jan '99

I don't know if this might be of general interest, but I would greatly appreciate any help. I am at the moment trying to set up a Zope server on a machine on which I don't have root access. The only problem is getting it to run on port 80. The admin mentioned something about making a suid root c-program that bound to- and turned over port 80 to a non-privileged Zope process. (I guess suid-zope would be a *bad idea*, since it's interpreted.) But I don't know how I can hand over a socket like that... Especially not how Zope would handle it... Any ideas? -- Magnus Lie Hetland www.pvv.org/arcadia <arcadia(a)pvv.org>

Of course, cache header management (which Zope currently doesn't do right at all) becomes more important. --Paul Paul Everitt Digital Creations paul(a)digicool.com 540.371.6909

- Moving the database...
by Magnus Lie Hetland 19 Jan '99

19 Jan '99

I tried to move the Data.bbb.* files from my old Zope server to my new one (from Solaris to FreeBSD) but it didn't work. I installed TinyTables, which I had installed on the original one, I set all the permissions, but still it wouldn't work. The server just died before I could get anything out of it. When I put back the original database, it worked again... -- Magnus Lie Hetland www.pvv.org/arcadia <arcadia(a)pvv.org>

The solution for me (using ZopeHTTPServer behind Apache) was to tell it explicitly what its SERVER_NAME, SERVER_PORT and SCRIPT_NAME environment variables are, then use them to construct URLs in my DocumentTemplates. Note that since I'm only using ZopeHTTPServer I don't have to worry about incorrect BASE tags showing up in my documents' <head>s.

- Passing around state information
by Konrad Hinsen 19 Jan '99

19 Jan '99

I am working on a small project based on ZPublisher (and I don't even want to think about how much work it would be without it!). One problem I have come across is how to provide some kind of "state information" or "pervasive user option". Almost all pages on my site have content that can be presented in various formats; essentially this is a user option. But it would be tedious for the users to specify this option over and over again. Ideally, they would make their choice once (on the starting page) and then forget about it. But somehow the information has to be passed on to the rest of my site. One solution would be cookies, but I'd like to avoid them for two reasons: many users disable cookies in their browsers, and I don't know how to use cookies with Zope. Another solution would be to attach the option to each and every URL and always pass it around. But I can't see how to do that with forms; I'd have to persuade the form to return a value that it has received itself via its URL, but which is neither displayed nor entered by the user.

Well... Now I installed Python and Zope anew on my FreeBSD box, and it worked wonderfully. I don't know what went wrong previously. (Oh, wait -- that might have been before the admin here upgraded the OS... Hm...) -- Magnus Lie Hetland www.pvv.org/arcadia <arcadia(a)pvv.org>

- Selling Zope to your organization
by Gabe Wachob 19 Jan '99

19 Jan '99

Hey folks- Has anybody here had to go through the experience of selling Zope (and Python) to your own organization over another technology (esp. Perl/CGI)? At Findlaw, we are largely an open-source shop (though, we find our selves still using NT/IIS for a few reasons), and the folks we have all use Perl. I've tried to extoll the virtues of Python to the team members, but usually the response is "Bah, Perl works, I know it, and I don't want to learn something new". I could take the dictatorial stance and say 'learn it', but thats not my style. I'd rather "sell it" to the folks so that we have buy in and enthusiasm. Zope seems like it could be a big part of that "sales pitch". That is, I'd like to be able to sit down with someone and show them how to write a "send mail to the webmasters" page without having to learn much Python at all. Has anyone had any success doing this? Has anyone used Zope as a way to get people using Python? What sort of resistance have people experienced in moving from Perl/CGI to Zope? Is performance ever cited as an objection? Having to learn a new language? The newness of Zope and Python? The relative lack of popularity of Python and Zope? Open-sourcedness? Single-sourcedness (of Zope), even if open source? Licensing issues (particularily the "logo" license requirement)? Apparent complexity? -Gabe
