i want to create an index page that displays whether or not a page has been updated in the past 7 days or the past 20 days. however, i can't figure out how to get the bobobase_modification_date to compare with ZopeTime. can someone give me a clue before i rush blindly down Zope's undocumented dark alleys. mike

Any examples of use of manage_addFile()?
by complaw＠hal-pc.org 13 Oct '00

13 Oct '00

I want to create a user-interface so that users can upload files to my Zope site. I have done this with DTMLDocuments, however I don't quite understand how to get the file itself into the Zope site via ... self.manage_addProduct['OFSP'].manage_addFile() ..that is in Python. I looked through the HOWTO's but didn't find anything. Does someone have an example of a Form/DTMLMethod/Python script that does this sort of thing? Thanks in advance, Ron ./.

Re: [Zope] Authentication headers & firewall port redirection

That would imply it tries to access > www.datadistilleries.com:8080/ddsn (Zope generated port) instead of plainly > www.datadistilleries.com:80/ddsn (firewall listen port). I know, that basic authentication is sent by the browser on a domain basis. I do not know, where the domain information originates, but it may well be Zope. You may want to use Shanes excellent "tcpwatch" utility to analyse what really happens between the server and your browser. Alternatively, you may have a look at SiteAccess. This Zope product helps you handle these forms of redirection. Even, if your authentication problem could be solved without it, you will soon hit other problems that require SiteAccess. Thus, go directly for it. Dieter

Topframe should be set or > true if the visitor arrived in the /Files Folder from the top level > frameset and /Files/ViewFrame will be loaded into the view_frame > target. The frameset and its frames parts are fetched in *different* requests. The "REQUEST.set" only affects the REQUEST object for the frameset. The REQUEST objects for the frame components are not affected. You have two options: * a session product (there are some around on zope.org) it allows you to save information across web requests * passing the additional information through a query string key=value pair (do not forget to "url_quote_plus") > XXX - If this method is called from the top level FrameSet method, > how to I access dir and file from the original request? see above.

Re: [Zope] Tiny tables

It interpretes ":<type>" suffixes of form variable and parameter names to call for a type conversion of the value. As far as I know, there is not escape possibility. Can you change the ':' into a different character? Dieter

proxied proxies with Zope & Apache
by Aaron Straup Cope 13 Oct '00

13 Oct '00

Hi, I have Zope set up running with Apache/SSL using mod_proxy and the SiteRoot product. Everything works fine. The thing is, if I understand stuff correctly, all the requests to https://hostname.com get handed off to Zope. I would like to be able use the same hostname for plain old Apache-isms (cgi php etc) because the users of the site shouldn't have to rememeber YA-hostname. I would like to be able to do the following : https://hostname/foo-->https://zope.hostname/foo -->http://hostname:8080/foo https://hostname/bar-->/htdocs/bar a) hostname:443 ProxyPass /foo https://zope.hostname/foo b) zope.hostname:443 ProxyPass / http:hostname:8080/ (where the SiteRoot in the Zope tree points to https://zope.hostname) When I try to do this, regardless of whether I use mod_proxy or mod_rewrite, Apache returns a 403 error : "You don't have permission to access /documents on this server." Should the Zope SiteRoot point to https://hostname instead of https://zope.hostname? I know that I could set up multiple ProxyPass statements (and corresponding SiteRoot objects) in the Apache conf file, but I would really prefer to set up a standalone Zope https setup (mostly for administrative purposes) and then proxy those aspects of Zope that are pubic automagically to the default Apache setup. I am dreaming? The rewrite/proxy stuff is still like voodoo for me most days so any advice or suggestions would be welcome. Thanks,

Re: [Zope] Medusa Monitor
by Hung Jung Lu 13 Oct '00

I know that, the stupid log file thingy. But you'll have to write an independent thread to display the log file (or peek the file manually each time), or implement some CString stuff to capture the file output (if that is possible). It'll be more fun if all this is already done, and the user can just tap into the monitor console screen (even remotely). A good monitor should actually display hit information, memory usage, etc, and preferably with charts, all in real time. Too much to ask? I don't think so. :) Hung Jung >From: Dieter Maurer <dieter(a)handshake.de> >To: "Hung Jung Lu" <hungjunglu(a)hotmail.com> >CC: zope(a)zope.org, jens(a)digicool.com, terry(a)adroit.net >Subject: Re: [Zope] Medusa Monitor >Date: Thu, 12 Oct 2000 23:47:35 +0200 (CEST) > >Hung Jung Lu writes: > > A more useful debuging tool would be some monitor where you can receive > > print message logs in real time.
