zope: accessing zsql methods from external methods (1.10.2 and 1.11pr1)
by Dr. Ross Lazarus 10 May '99

10 May '99

I'm stumped. I need a simple example of how to get an external python method to grok a working zsql query. I have a zsql query which works fine, called showcont, returning the entire contents of a small table. I have a simple external method based on the hint on page 11 of the zsql methods user's guide which implies that an external method should get something useful back from showcont() - I've stripped it to the basics so I expect to get some horrible but familiar text back without adding any python complications - I just want this to work !!! ===========testzsql.py in Extensions directory # testing external methods def test(self): s = '' for cont in showcont(): for contitem in cont: s = s + contitem + '<BR>' return s ========= The external method is loaded into the same folder as the zsql method and function test is called as testzsql. I put a  into a dtml method and get...tracebacks. Basically, they all point to the fourth line - the showcont() call seems to break. This doesn't seem to work for 1.10.2 or 1.11pr1 - both running under nt4/sp4 using the simple server. At least I get better error messages from the fixed externalmethods in 1.11...

Re: [Zope] Why doesn't this work?

Thanks for the tip, I'll do that. Do you know of any zopish way to render the URL of the top level directory (without knowing where you are in the folder hierarchy)? This would be more elegant as a generic solution. The plus side of not using the absolute URL is that I could have a local version of 'folderimg' if I wanted, without having a local version of the method.

ZServer 1.11 FTP problems
by Alexander Staubo 09 May '99

09 May '99

When upgrading to 1.11, I copied the Data.bbb.* files into the new installation. Could this explain why the FTP server doesn't work properly? Even when logging in as the "superuser", the only directory I can change to is /QuickStart. All the other directories in my Zope installation give a "550 No such direcrtory" error. I get the error even when I do "cd /". Furthermore, if I do a "dir" on root level I get "Could not list directory". The log doesn't show any errors, though.

RE: [Zope] More than one Zope site for one Zope installation ?
by Alexander Staubo 09 May '99

09 May '99

What if Zope used the Host: header field to target a specific subtree? For example: / foo.org index_html ... bar.org index_html ... Assuming a request like this: GET /index_html HTTP/1.1 Host: www.foo.org then Zope could look at a table of virtual server name mappings (such as www.foo.org -> foo.org -- could be implemented through properties), find the correct subtree, and assume this to be the server root. So www.foo.org/index_html would in this case map directly to /foo.org/index_html. As far as I can see, Zope currently ignores the HTTP 1.1 Host: header.

Quota support
by Dan Feldman 09 May '99

I am interested in setting up Zope as a system in which users can create their own folders and homepages. However, since I don't have much space to do it in, I'd like to give each user a fixed quota of disk space. Is there any easy way to do this? what about using an External Method? Thanx,
