How to debug access denials?
by Stephane Bortzmeyer 14 Dec '00

14 Dec '00

I have problem with Zope security model and I would like to know the best way to debug Zope when access is denied. I have two experimental sites: on one of them, anonymous users can go everywhere. On the other, the permissions *look* exactly the same but anonymous users can only see the home page and are denied access to subfolders (more precisely, Zope asks a password). I assume one DTML method, in the second site, is doing something forbidden (anonymous has "View" and "Access content information"). Is there a way to get an extended log, such as "anonymous user denied because index_html called standard_html_header which called getData and getData is a database connection and they don't have permission to use database connections"?

Start with Zope

Hello, I'm a newbie with Zope and maybe the question I will pose is really stupid but please help me. I'd like to use Zope with Linux ( I'm under a Debian), I installed Zope but I can't start using Zope to make a new web site. I verified that Zope is running but I don't know how to start this program to start building my new web site. May I have to configure something ? I have read lots of things about Zope but I wasn't able to start ... please help me ... Thanks a lot I hope you'll help me. Pierrick

HTML formatting from a text field

Ausum, I would suggest going to the website for Lotus Quickplace (www.quickplace.com or www.lotus.com) and signing up for a demo account. They've got a very simple word processor (bold, italics, a couple of fonts, etc.) integrated into their project sites that, I think, does what you're describing. I'm pretty sure everything is accomplished using Javascript. If you could port something like this over to zope and release it as a product, so that WYSIWYG documents can be created through the web and still incorporate standard headers and footers, I would be a very happy man. I dread trying to explain zwiki and structured text to clients. You might also want to look at standardbrains.editthispage.com. He's got an excellent, javascript-based approach to WYSIWYG editing, but you can't save it back to the site as far as I can tell. David

Don't need answers like "but gopher is old, ugly, etc", "we > will loose all fomatting, etc", etc. ZServer (aka medusa) is protocol agnostic; I would look at the Request/Responses there, plus their equivalents in lib/python/ZPublisher, and try to fold in Python's gopherlib module with them (check out ZServer/medusa/http_server.py, as well). > Thanks, > > /dario :)) > > read all about it: > gopher://gopher.heatdeath.org/00/the%20gopher%20manifesto.txt Tres. -- =============================================================== Tres Seaver tseaver(a)digicool.com Digital Creations "Zope Dealers" http://www.zope.org

What version of Python Methods - no - Scripts for 2.2.4?
by Ronald L. Roeber 14 Dec '00

14 Dec '00

Quesrion(s): Is the recommended install of Python Scripts for Zope 2.24 this? http://www.zope.org/Members/4am/PythonMethod even though it appears to be exactly one year old today (13-Dec)? This is also the date in the CHANGES.txt file in 2.3_a1 PythonScripts directory. Can I just copy the PythonScripts product from my 2.3_a1 Products directory to the appropriate location on a 2.24 server or should I use the PythonMethod from above? Are there implications for upgrades from Methods to Scripts? Am I missing something(s)? (probably) Please advise. Sorry to be so confused. Thank you. ron...

Re: [Zope] PIL problem

Sorry for the late reply, I don't check this list until after work. If you have X windows and you have fonts in the bdf or pcf format you can use the script that comes with PIL called pilfont.py to create fonts. Also, I took a few of my fonts, formatted them, zipped em up, and put them in my zope.org member folder. <a href="http://www.zope.org/Members/byron/fonts.tar.gz">http://www.zope.org/Members/byron/fonts.tar.gz</a> hope this helps.
