I am trying to use carrierwave, fog and AWS for my image uploading on Heroku. Pretty common...I even have it set up successfully for another app. However when I delpoy to heroku I'm getting this error:
Running: rake assets:precompile rake aborted! NameError: uninitialized constant CarrierWave::Storage::Fog

! Push failed
I've been googling this and looking at similar questions on stackoverflow and can't figure it out. I'm sure it's something simple.
I've encountered this problem repeatedly across various projects, and I typically fix it by defining the CarrierWave::Storage::Fog class myself, as an empty class, in an initializer.
Amazingly this seems to work, and it doesn't seem to interfere with Rails' ability to load the real class:
# config/initializers/fix_fog.rb
module CarrierWave; module Storage; class Fog; end; end; end
I've deployed this several times, since at least February 2016. It doesn't seem like a great solution, and I'd be interested in alternatives.
