permission problem????

In folder 'test' I have created an 'acl_users' folder with userid of 'testuser'. There's the sample index.html that get's created along with the folder. 'testuser' can see this fine. I then proceed to create a ZSQL method, connecting to my Postgres7.4 database with ZPsycopg. The sql method works fine as superuser. However, when 'testuser' attempts to use the sql method, I get: Site Error An error was encountered while publishing this resource. KeyError Sorry, a site error occurred. Traceback (innermost last): Module ZPublisher.Publish, line 150, in publish_module Module ZPublisher.Publish, line 114, in publish Module Zope.App.startup, line 202, in zpublisher_exception_hook Module ZPublisher.Publish, line 98, in publish Module ZPublisher.mapply, line 88, in mapply Module ZPublisher.Publish, line 39, in call_object Module OFS.DTMLDocument, line 126, in __call__ Module DocumentTemplate.DT_String, line 474, in __call__ KeyError: standard_html_header (Also, an error occurred while attempting to render the standard error message.) ---------------------------------------------------------------------------- ---- Troubleshooting Suggestions The URL may be incorrect.

dumb TinyTable
by Michael A. Ruberto 17 May '04

17 May '04

I am trying to put some data from a .csv file exported from Excel into a TinyTable via copy and paste :( I keep getting errors like: invalid token '/' at line 3 column 12 so I change the / to "or" and get: invalid token 'or' at line 3 column 13 now if I enclose the data with "" the error goes away. now I would much rather attempt rewriting some of the Tinyable's code than edit these .csv files. has anybody done this already? if it has been done please don't let me reinvent the wheel... THANKS!! Michael A. Ruberto DORTRONICS SYSTEMS INC.

Re: scheduling python script to execute at certain time and day

Some time ago, Sean Upton adviced me not to use cron + wget. He found this a bad solution and instead recommended to use to use Zeo + cron. I think that this is better than the first approach, but the problem is that you have to enable Zeo. In fact, I'm not using Zeo, so I haven't tried it. However, here is the thread if you are interested: http://mail.zope.org/pipermail/zope/2003-March/132279.html Regards, Josef. >Laura McCord wrote: > > I finished writing a python script that deletes files that are a > > certain age.

Debian needs a lot more than a little update, like a boot to the happysack, but thats neither here nor there. I would strongly advise against using the Debian package for Zope. > Is the mod_proxy use described in zope 2.7's WEBSERVER.txt ? No, WEBSERVER.txt is just misleading documentation that ships with Zope for no good reason. Despite that FastCGI *can* be used, as you've found out, it doesn't really work all that well. The mod_rewrite technique isn't documented in that file, but it is documented in the Zope Book online, which you should read, its full of good information. The thing you need to understand when it comes to setting up Zope, is that there is really only 1 good way to do it, and a lot of somewhat crappy ways to do it, which people tend to continue to offer as viable alterntatives, even though they aren't. The 1 good way, is to put an HTTP gateway server in front of Zope's ZServer, and tell the gateway to sanitize and rewrite requests before handing them to ZServer. Generally this means you bind ZServer to the loopback interface of your host on an unpriviliged port (it defaults to 8080, but thats a stupid default as 8080 is already commonly used by proxy servers; thats one thing Debian did well, was default to a more reasonable port), then forward requests from your gateway server (usually listenting on port 80 and/or 443) to the loopback interface where ZServer is listening. When using apache as your gateway server, the best technique is to use mod_rewrite w/mod_proxy loaded for the [P] option, as documented in the Zope Book. There is another technique which uses mod_proxy's ProxyPass directives, but that technique isn't as flexible and is more prone to painful misconfigurations that lead to security holes. I really wish people would stop recommending the latter technique or even documenting how it works, but unfortunately, it too is mentioned in the Zope Book. -- Jamie Heilman http://audible.transient.net/~jamie/ "Paranoia is a disease unto itself, and may I add, the person standing next to you may not be who they appear to be, so take precaution." -Sathington Willoughby

Hi, I finished writing a python script that deletes files that are a certain age. How would I get zope/plone to execute this python script at noon everyday. What types of things do I need to do? Thank, Laura
