Rails 4 Runtime error in controller: Circular dependency detected while autoloading constant

Let me know if I left anything out. I can't figure out why my views/references/ folder isn't accessible. neither

new.html.erb
nor
index.html.erb
is available. When I go to
localhost:3000/references
my error is:

RuntimeError in ReferencesController#index
Circular dependency detected while autoloading constant ReferencesController


I believe this is setup, and It shouldn't be a Rails issue because my other controllers are working fine.

My routes file has
resources :references
in it, my rake routes produces:

references GET /references(.:format) references#index
POST /references(.:format) references#create
new_reference GET /references/new(.:format) references#new
edit_reference GET /references/:id/edit(.:format) references#edit
reference GET /references/:id(.:format) references#show
PATCH /references/:id(.:format) references#update
PUT /references/:id(.:format) references#update
DELETE /references/:id(.:format) references#destroy


So I try to get to my index page by this which should be the correct path.

<%= link_to 'References', references_path, class: 'navbar-brand' %>


My model:

class Reference < ActiveRecord::Base
belongs_to :user
end


My controller:

class ReferencesControllers < ApplicationController
def index
@references = Reference.all
end


After Google searching, every similar problem seems to be when upgrading from Rails 3 to Rails 4, or updating from OS to mavericks. My other controllers work so I feel it's safe to rule those out. I can't even get to the templates.

Answer

Rename this ReferencesControllers to ReferencesController
