Actually it's even easier. It's a builtin. You can refer to INSTANCE_HOME anywhere in a Zope app and it will be returned. On Fri, 2002-11-08 at 17:20, Charlie Reiman wrote:

Admittedly, I spent 5 minutes searching and no joy...

How does one access INSTANCE_HOME in an external method?

The logic I need is something like this--I'm just missing the incantation for my fanciful getZopeEnviron.

Help?

# a fanciful dream...

import os

def dostuff(self):

location = self.getZopeEnviron("INSTANCE_HOME", None) if not location: location = self.getZopeEnviron("SOFTWARE_HOME", None) if not location: raise PukeOla("What the f---?") import_dir = os.path.join(location, "import") # Now we're cooking with fire...

Cheers,

If possible, please put a comment in the advanced scripting chapter of the zope book noting that INSTANCE_HOME and SOFTWARE_HOME are builtins. Tks! - C On Fri, 2002-11-08 at 17:48, Mark McEahern wrote:

Chris, that did the trick! Thanks!

Now, I'm curious how I would find this. It's always interesting to see--even when you know the answer--what sort of google search would turn it up? Google search or searching zope.org's site?

This search:

http://www.google.com/search?q=instance_home+zope+python+software_home&btnI= I'm%20feeling%20lucky

gives some hints.

Anything more explicit? For what it's worth, I would expect to see this in the API reference, but it's not there (afaics). Or in the chapter on advanced scripting:

http://www.zope.org/Documentation/Books/ZopeBook/current/AppendixB.stx http://www.zope.org/Documentation/Books/ZopeBook/current/ScriptingZope.stx

(Not that I looked either place. <grin> Anyway, blimey!)

It's just an enviornment variable, so I assume:

import os os.getenv('INSTANCE_HOME')

should work for an external method.

I'm using Zope 2.6.0b2 on Windows--running as a service. Here's the external method contents (below). When I test it, I get HomeNotFoundError. Which suggests that Zope does not set these environment variables for me--I must set them myself. Am I missing something? Thanks, // mark # external method import os class UtilsException(Exception):pass class HomeNotFoundError(UtilsException):pass def import_file(self): location = os.getenv('INSTANCE_HOME') if not location: location = os.getenv('SOFTWARE_HOME') if not location: raise HomeNotFoundError imp_dir = os.path.join(location, 'import') return '\n'.join(os.listdir(imp_dir)) -
