I've defined a module in a file directly in my app folder, but am unable to use its methods in an ActiveRecord class (methods not recognized). As I understand it, files in the app folder are supposed to be required automatically by rails.

I've also tried to include it manually:

```
class Picture < ActiveRecord::Base
    include Curation
    ...
end

```

but I get 

```
NameError: uninitialized constant Picture::Curation 

```

Am I mistaken about this, and actually do need to manually require all new files?
