Unable to autoload constant, expecting FILEPATH to define it - in other words, huh?

Question

When I try to access my localhost, I get the following message.

**LoadError in ListingsController#index

Unable to autoload constant Listing, expected C:/Sites/redemo/app/models/listing.rb to define it**

This is the code it refers to in listings_controller.rb

# GET /listings.json
  def index
    @listing =Listing.all
  end

My listing.rb is as follows:

 class Listings < ActiveRecord::Base
        mount_uploader :image, ImageUploader
 end

Please, what else am I supposed to do to define it?

Answer 1

You check your model definition. While controller is Listings , model should be Listing Therefore change to this;

class Listing < ActiveRecord::Base
     mount_uploader :image, ImageUploader
end
