Suggestion: simplify resource directory structure

[climatebrad]

It seems spurious to have resources saved at files/resource/{id} instead of simply files/{id}. Was the idea here that people can subclass Resource? (Even if they do, {id} will keep things unique.)
I recommend changing

  def store_dir
    "files/#{model.class.to_s.underscore}/#{model.id}"
  end

to

def store_dir
  "files/#{model.id}"
end

in app/uploaders/resource_uploader.rb

(Alternatively, if the model name is kept, would make more sense to be at #{model.class.to_s.pluralize.underscore})
