LoadError, "Unable to autoload constant #{qualified_name}, expected #{file_path} to define it" unless from_mod.const_defined?(const_name, false)

I am using rails 5 and unable to get the image uploader to work. When I try to upload the image nothing shows up and if I step through with byebug I get to this error. Any idea what could be causing this? From what I am reading it is saying that module names can only have a capital first letter and the gem uses RedactorRails

Having exact same error, have you solved this?

edit: I solved this myself turns out the one of the controller files had a typo.

I had UserControllers < ApplicationController
should be UserController < ApplicationController

so make sure your controller files are proper if you're having this same error.

I'm having the same issue as well. It doesn't appear to be documented.
