Zope Error: The specified module couldn't be found.

Question

Hi folks,

I'm trying to add and external method to a Zope site. I've created an Extensions directory under zinstance and put a file named example.py there. The example.py file just has

def hello(self):
    return "Hello World!"

When I try to add the External Method I get a message:

Site Error

An error was encountered while publishing this resource.

Error Type: NotFound
Error Value: The specified module, 'example', couldn't be found

I've tried restarting Zope, that didn't help.

I'm wondering what kind of dumb mistake I'm making.

Thanks for your advice.

External methods need to be in a directory named "Extensions" inside of a product directory. Try running the following commands from your zinstance directory:

mkdir -p products/Examples/Extensions
touch products/Examples/__init__.py
cp Examples/example.py products/Examples/Extensions/
./bin/instance restart

Then create an external method like this after Zope has restarted:

id: whatever
title: optional
Module name: Examples.example
Function name: hello

You should then be able to test the external method via the Test tab in the ZMI.

No joy, same result after creating the init.py I did see that init.pyc was created though.

I've added some extra steps for creating the external method object in Zope - can you please try again?

It worked, no error message and it shows up in ZMI. Thanks!
