I've organized a model and it's embedded models in sub-folders of app/models to better separate concepts. For instance, I put a model SomeModel into:

  app/models/example/some_model.rb

When I run

  rake db:mongoid:create_indexes

I get

 
 Expected /..../app/models/example/some_model.rb to define Example::SomeModel

If I don't put models and their embedded models into sub-directories of model it quickly takes unnecessary thinking to separate concepts.

Please let me know if you think the current behavior is convention and suggest a different practice if you know a better one.

Thanks.
