LocalFS Question
by Jim Sanford 22 May '00

22 May '00

Does anyone out there know how I can prevent LocalFS from translating CR/LF pairs in a text file to LFs when serving up the file? Or will I need to "massage" it in Zope before sending it? In this case the files are Windows/DOS batch files. They will not run with the CR/LFs replaced with LFs. Jim Sanford

Zope + Apache + Mailman
by pehr anderson 22 May '00

22 May '00

Dear Mailmen, I've been studying this all weekend and finally, *finally* understood enough to get it to work. I wanted to proxypass both sites into zope, however I needed access to CGI scripts and images to run mailman. I had to find the appropriate rewrite rule to allow this to work. The zope Zserver serves pages on port 8080. Apache has the ability to proxy this on port 80 either through "ProxyPass x y" which gives you very little control or through "RewriteRule x y [proxy]" which gives you tremendous control. In zope I have two SiteAcess objects. One at the root, says "http://morseall.org", "/" and the other inside /osm says "http://osm.cx", "/" This worked with the following configuration: Redhat Linux 6.2 apache-1.3.12-2.i386.rpm Zope-2.1.6-1.i386.rpm Zope-zserver-2.1.6-1.i386.rpm # added to /etc/httpd/conf/httpd.conf ScriptAlias /mailman/ "/home/mailman/cgi-bin/" Alias /pipermail/ "/home/mailman/archives/public/" <VirtualHost 24.218.234.247> ServerName osm.cx RewriteEngine On RewriteOptions 'inherit' RewriteRule ^/icons(.*) - [last] RewriteRule ^/mailman(.*) - [last] RewriteRule ^/pipermail(.*) - [last] RewriteRule ^/(.*)$ http://localhost:8080/osm/$1 [proxy] ProxyPassReverse / http://localhost:8080/osm/ ProxyPass /p_ http://localhost:8080/p_ ProxyPass /misc_ http://localhost:8080/misc_ </VirtualHost> <VirtualHost 24.218.234.247> ServerName morseall.org RewriteEngine On RewriteOptions 'inherit' RewriteRule ^/icons(.*) - [last] RewriteRule ^/mailman(.*) - [last] RewriteRule ^/pipermail(.*) - [last] RewriteRule ^/(.*)$ http://localhost:8080/$1 [proxy] ProxyPassReverse / http://localhost:8080/ </VirtualHost>

Executing an external program
by Mabe, Brad 22 May '00

22 May '00

Is there a way for zope to call an external program (exe, batch file, etc.) and have it execute on the server? I have several home grown utilities on my server that I would like to access/execute via the browser. -=Brad=-

First, your program returns a non-zero exit status. Second: "f.close()" returns a simple integer, not a sequence that may be indexed. Remove the "[1]" from status and you should see the nonzero exit status. Dieter

Zope Pgsql 7.0/SQL Schema HeLp!
by Richard Smith 22 May '00

22 May '00

This is going to be a long winded questions. Ok I have been hacking around with Zope and Pgsql for awhile now. I am trying to learn both at the same time, not any easy task, I don't know SQL that well. I learn by doing ,and this is really fun, kinda like a digital puzzle of sorts. So any way I set up a database in pgsql to hold contact information. This was no small task for me, like I said, I am new to SQL. I did discover a neat way to use CREATE VIEW foo AS SELECT that is not in the book though. Anyway the PRIMARY KEY for the table of names is a SERIAL type, all other tables such as phone numbers and addresses use REFERENCES to this KEY. The database works quite well, I think I have it normalize as much as need be (bare with me I am still learning). Now on to Zope I have Zope all set, and I can run all your standard SELECT, INSERT, UPDATE stuff. But I have one hitch, I can't seem to figure out how to make it so an end user could add a name and email address without knowing about the PKEY number. This is no problem for a DBA but I want to make it easy for anyone to INSERT and UPDATE records. Did I make a bad design choice in use unique numbers to glue all the tables together. Is this an interface problem. Am I missing something. I need some help. Can someone point me in the right direction please? Richard

ZWiki is the real product and I'd like to thank Simon for giving us such an amazing product. cheers, Chris PS: Now, if I could just rename a Wiki page through the Wiki interface and have all links to that page updated... ;-)

That's not good :( That means something is causing the requests to go astray. Can you see what the requested object is compared with the URL you would expect? cheers, Chris

Re: [Zope] ZClass acting up?

Yeah, but what you should probably do is to make the top ZClass one of the base classes (but do not add it along with the Object Manager - then you loose the recursiveness as well... don't know why) of the ZClass you want to be recursive; as I did. > I misread your original note.

Could anyone clarify this, please? -- Erik Enge
