uninitialized constant Car::PictureUploader

I'm trying to add a Picture Uploader in app/uploaders but am getting this error when loading my app:

uninitialized constant Car::PictureUploader on line 3 of car.rb

app/models/car.rb

class Car < ActiveRecord::Base
  belongs_to :user
  mount_uploader :picture, PictureUploader
  validates :user_id, presence: true
  validates :year, presence:true, length: { maximum: 4 }
  validates :brand, presence:true

app/uploaders/picture_uploader.rb

class PictureUploader < CarrierWave::Uploader::Base
  storage :file

  # Override the directory where uploaded files will be stored.
  # This is a sensible default for uploaders that are meant to be mounted:
  def store_dir
    "uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
  end

  # Add a white list of extensions which are allowed to be uploaded.
  def extension_white_list
    %w(jpg jpeg gif png)
  end
end

I've gotten this error before when the file equivalent to picture_uploader.rb wasn't in the correct folder, but I think everything is in order here. When I comment out line 3 in user.rb the page loads. Any idea on how I can get my page to run?

Just restart your server. It'll fix the issue. Everything is ok in your code.

Had the same error and had to manually kill the server process:

ps aux | grep server
kill [server process id]

For some reason shutting down the server with Ctrl+C earlier didn't seem to have worked.

I think you want:

::PictureUploader

Which specifies that it's just the class PictureUploader not a class PictureUploader within the namespace Car.
