Uninitialized constant errors in Rails 3 Model classes

[divvan]

I'm new to Rails 3 and simply_stored. When I try to create a Model class (such as User) with the line 'include SimplyStored::Couch', I get an error:

class:User': uninitialized constant User::SimplyStored (NameError)".

In the 'Usage' section of your website, it says to include the lines:

require 'simply_stored/couch'
CouchPotato::Config.database_name = 'couchdb_test'

But I'm not sure where these should go. I've tried putting them in a file 'config/couchdb.rb', and in the Gemfile, but it doesn't make any difference.

I'm using Rails 3.0.0.rc2, simply_stored 0.3.9, couch_potato 0.4.0, couchrest 1.0.1, and CouchDB 1.0.1, running on Windows XP SP3.

Thanks for your help.
