here is an opportunity to use a ruby Class (maybe called DropboxFile) that can store the contents and metadata you get from the Dropbox API. similar to how you asked about APIs and Rails models, we can define custom methods in the DropboxFile Class:

```ruby
class DropboxFile
	attr_reader :contents, :metadata
	# using attr_reader since we only want to set the contents and meta-data
	# when we create the object. the rest of the time will just be reading this data,
	# never editing or updating

	def initialize contents, metadata
		@contents = contents
		@metadata = metadata
	end

	# executed when calling "puts dropbox_file_object"
	# will output @contents of the object
	def to_s
		@contents
	end
end
```
