Is there a way to read a file object using Fog and CarrierWave?

I'm using CarrierWave and Fog to store attachments to an ActiveRecord model on S3. I can use them to generate the URL, but I can't seem to locate any method to actually read a file.

Is this something that the Fog gem will even do, or do I need to use the S3 gem for that?

You can use the read method on the uploader object. If we have a model called MyModel which has a field called attachment which was added using CarrierWave's mount_uploader method, we can do the following:

obj = MyModel.first
contents = obj.attachment.read

This will get the actual contents of the file. Check out this doc.

You just require open-uri

require 'open-uri'
file_contents = open(string_url) {|f| f.read }
