DRb server & aaf gem

Ruby Apps Ferret
1

I’m having problems getting the DRb server running with the aaf gem.
I tried it with the plugin installed in my application, and it
worked. I suspect the problem has something to do with the startup
scripts expecting certain files to be in certain relative file paths.

Any insights are appreciated, and maybe if you have time you can
update the wiki document :slight_smile:

Thanks for a great tool.

I guess you did create ferret_server.yml in RAILS_ROOT/config?
What’s the exact error you get?

I just gave it a try :wink: However there’s no gem-specific info yet, I’ll
try to throw a script together that eases setting up a project to use
the aaf gem.

cheers,
Jens

Yes, I created the ferret_server.yml in /config and added the remote
declaration to my models. Then I put the three startup scripts into /
script/aaf/, and I was trying to run them from there. I got errors
similar to the ones in the comments of your blog post announcing AAF
0.4.0[1]

A blog post[2] mentions something that I think the wiki does not,
“add AAF_REMOTE = true to your environment file”. Is this necessary?

Thanks,
John

do you have ‘require ‘acts_as_ferret’’ somewhere in your
environment.rb?

what version of Rails do you use?

J4i, the AAF_REMOTE environment variable is only used in aaf unit tests
to determine if the tests should run in local or remote mode, it’s not
used elsewhere and therefore won’t help, but can’t hurt much either :wink:
I also added a comment clarifying this to the blog post you mentioned.

This is actually not correct. Here is the error I am getting:

That did the trick! (I didn’t need to require AAF in the environment
before because I was requiring it in the models)

what version of Rails do you use?

1.2.2

J4i, the AAF_REMOTE environment variable is only used in aaf unit
tests
to determine if the tests should run in local or remote mode, it’s not
used elsewhere and therefore won’t help, but can’t hurt much either :wink:

Great. Care to note this on the wiki as well? :slight_smile: I was going to but
did not feel confident about wording it properly.

Thanks,
John
