Getting: “Couldn't find SessionsHelper, expected it to be defined in helpers/sessions_helper.rb”

Question

I am getting the following in my log file upon loading /login/.

Started GET \"/login\" for 120.138.93.108 at 2016-01-02 03:06:24 +0000

Act

Answer 1

In my case, I had an :

include ModuleName

pointing to a non existing module in a model. This one has been previously removed but I had miss the reference.

I had the exact same "Couln't find ..." error with every helpers I have in my app so it was pretty difficult to find out where the problem came from.
