uninitialized constant CustomersController - Rails

I'm having trouble with my routing in a Rails app. I get this error when I try to follow a link to the new_customer_path: 

uninitialized constant CustomersController

This is the link I am trying to follow. It is on the "new" page for my Movies controller. Here is the relevant portion of the "new" page: 

<div class="row">
<div class="col-xs-12">
    <hr />
    <%= link_to "Add Customer", new_customer_path, class: 'white' %>
</div>
</div>

Customer Controller: 

class CustomerController < ApplicationController
  def new
    @customer = Customer.new 
  end

  def create
    @customer = Customer.new(customer_params)
    if @customer.save 
      redirect_to new_customer_path
    end 
  end

  private 

   def customer_params
    params.require(:customer).permit(:fname, :lname, :telephone, :email)
   end

end

Routes: 

Rails.application.routes.draw do
  resources :customers

  resources :movies do 
    resources :rentals
  end 
  root 'movies#new'
end

Customer Model: 

 class Customer < ApplicationRecord
    has_many :rentals 
 end

Any thoughts/tips would be very much appreciated!

Could it be that you're missing an s?

class CustomerController < ApplicationController should be class CustomersController < ApplicationController

Rails is convention over configuration which means:

  • Models are singular: Object
  • Controllers are plural: ObjectsController

This can be changed if you would like, but I would stick with convention unless you have a good reason.
