Where should I place my middleware file for Rails 5.1?

Question

Previously I had my middleware under lib/middleware/my_middle_ware.rb

However when doing this,

config.middleware.use MyMiddleWare

I receive a

NameError: uninitialized constant

Where is rails looking for the middleware?

Answer 1

Look like rails wasn't looking for it.

I had to do the following for it to work.

Dir["./lib/middleware/*.rb"].each do |file|
  require file
end
