Get a member URL action with ActiveResource

I have a route in my application that is like this:

/deployments/:id/logs.json

It is used to retrieve logs for a specific deployment. On my client code, based in ActiveResource I have this:

logs = Deployment.find(deployment.id).get(:logs, opts)

Where opts is some parameters that I send via query string.

The problem with this code is that it breaks the request in two. The Deployment#find method requests:

GET /deployments/:id.json

And then, if this is found, a second request is sent:

GET /deployments/:id/logs.json

Is it possible to skip the first query altogether using Rails 3 on the server and ActiveResource (current requirements for activeresource is >= 2.3.5 but I am fine with bumping it if needed)?

UPDATE: I think it works if I change:

logs = Deployment.find(deployment.id).get(:logs, opts)

to

logs = Deployment.new(:id => deployment.id).get(:logs, opts)

Any comments?
