I am receiving the following error message when attempting to authenticate with Facebook in a rails app using MongoMapper:
It appears that MongoMapper is not being loaded properly, but I am not sure why. In my Gemfile I include gem 'mongo_mapper, gem 'bson_ext', and gem 'omniauth-facebook', '~> 1.4.1'. I also followed the setup instructions here: http://mongomapper.com/documentation/getting-started/rails.html to completion. I am able to run the $ mmconsole, as well as connect to the mongod using the $ mongo. Is there another configuration step that I missing to ensure that mongo_mapper can be loaded properly? Thanks in advance for any assistance, I am new to MongoDB in general.
EDIT:
Here is what my SessionsController looks like, where the LoadError originates:
