Zope Book Beta
by Michel Pelletier 01 Nov '00

01 Nov '00

Amos and I are gibbering like madmen with excitement to announce the Zope Book Beta. This is the complete, technical draft of the book with all screenshots (but minus illustrations, those are on there way!). Some other things like a colophon and information about the authors is missing. The beta includes all completed chapters, the API reference, and the DTML reference. We've received over a hundred comments, corrections, and ideas from you the community and it has made a much better book. This is the one to print out and give to your friends as christmas gifts, folks, so get crackin and start reading at http://www.zope.org/Members/michel/ZB/. Enjoy, -Michel

preventing acquisition
by Robin Becker 01 Nov '00

01 Nov '00

I have some folderish Zclasses which have index_html methods to implement a UI. I would like to inhibit acquisition of these. So if I have a path /A/B/C I would like to inhibit the behaviour that allows me to view /A/B/C/A and /A/B/C/A/B/C etc. to inhibit the first I can put something like <dtml-if "PARENTS[0].id not in PARENTS[1].objectIds()"> <dtml-raise NotFound> <h2>You're not supposed to be looking at <dtml-var "absolute_url()"> </h2> </dtml-raise> </dtml-if> in my index_html, but this doesn't work for the second case. Is there a generic way to do this? -- Robin Becker

Sorry, resolved

Just had to add an "index_html" to the ZClass, now it works. So it looks as if "looking for index_html" starts at the ZClass itself. thanks for listening anyway ;-) Danny -----Ursprüngliche Nachricht----- Von: zope-admin(a)zope.org [mailto:zope-admin@zope.org]Im Auftrag von Danny William Adair Gesendet: Dienstag, 31. Oktober 2000 19:38 An: zope(a)zope.org Betreff: [Zope] Change rendering of a folder Hi, I would like to subclass the folder class and change the way it gets rendered. How would no how will I do that? Usually, a folder object looks if it contains a index_html and calls(renders) it if so. I would like to change this behavior and call a method of my own when the object gets rendered. I remember the rstx_document example, where you subclass from the original and add "Renderable" to the base classes(I think it was important which first), then provide a "render" method in your new ZClass and that's it. This didn't work for "Folder". btw, would I subclass from "OFS: Folder" or from "ObjectManager"? tia, Danny _______________________________________________ Zope maillist - Zope(a)zope.org http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )

It is very easy to make them persistent. When I remember correctly, it was only necessary to pass "commit" to Gadfly. Dieter

Mapping tools with Zope
by twiens 31 Oct '00

31 Oct '00

I'm researching for a project that will probably use Zope. For this project we will require a simple GIS component for display and information retrieval. I've noted three possible products so far and I'm wondering if anyone has any experience with these products or with others. My interest is what worked well, what didn't and how difficult were they to use with Zope. The products I've identified as potentially useful are: MapIt, MapServer and OpenEV. So far the MapServer seems to be the most likely candidate for our use. Thanks in advance. T PS. I'm posting this a second time as I accidentally posted the first message as part of the Zope Book Beta thread. Sorry. -- Trevor Wiens twiens(a)compusmart.ab.ca The significant problems that we face cannot be solved at the same level of thinking we were at when we created them. (Albert Einstein)

The "doc/WEBSERVERS.txt" contains some information about how to convince Apache to pass "REMOTE_USER". I am not sure, it will be enough for you. Dieter

Re: [Zope] incorporating generated sub-websites within a Zope site

Fred Yankowski writes: > ... publishing content created with standard web design tools via Zope ... There have been some discussions about this in "zope-dev" in relation with "HiperDOM" and "XHTML" templates. Maybe, you search the "zope-dev" archive to get an overview. As far as I know, DC plans to support such publication. HiperDOM might already go some way into this direction (for tools that generate XHTML). There is an easy way to provide header and footer to your content -- provided you are ready to use a bit uncomfortable URLs, i.e. to view an object with URL "u", you use "u/view". "view" is a method (DTML or PYTHON) that operates on "u". It removes the header and footer in "u" and replaces it with header and footer of your choice, after passing values extracted from the original header to the new header (e.g. title, link, meta tags). With some advanced Zope, maybe the "Traversable" product, it might be possible to get around the additional "/view" URL suffix. Dieter

Yes, but you have to do in it a round about way. (Actually, I've seen mention of a patch to Apache that does this, but I don't think it's neccessary) Here's the setup I'm using: RewriteEngine On RewriteRule ^/Zope(.*) http://localhost:8080/$1?client_ip=%{REMOTE_ADDR} [QSA,L,P] RewriteRule ^/p_/(.*) http://localhost:8080/p_/$1 [L,P] RewriteRule ^/misc_/(.*) http://localhost:8080/misc_/$1 [L,P] In this case, REMOTE_ADDR will be available in the REQUEST namespace under "client_ip" HTH > -----Original Message----- > From: Aaron Straup Cope [SMTP:asc@vineyard.net] > Sent: Tuesday, October 31, 2000 5:47 AM > To: zope(a)zope.org > Subject: [Zope] Zope & Apache/ProxyPass : environment variables > > Hi, > > Does anyone know if it is even *possible* to pass environment variables > (specifically REMOTE_USER) to Zope when it is set up behind > Apache/ProxyPass. > > I've looked around the list archives, and the Apache docs and tried a > bunch of different configs but nothing works.
