Uninitialized Constant (NameError)

[sunnyrjuneja]

Hey Steve,

This is probably not a bug and likely to be bad user behavior.

My generator looks like this:

# lib/generators/wine_bouncer/initializer_generator.rb
module WineBouncer
  module Generators
    class InitializerGenerator < ::Rails::Generators::Base
      source_root File.expand_path('../../templates', __FILE__)

      desc 'Creates a sample WineBouncer initializer.'
      def copy_initializer
        copy_file 'wine_bouncer.rb', 'config/initializers/wine_bouncer.rb'
      end
    end
  end
end

My spec looks like this:

# spec/lib/generators/wine_bouncer/initializer_generator_spec.rb
require 'generator_spec'
require 'rails_helper'
require 'spec_helper'

describe WineBouncer::Generators::InitializerGenerator, type: :generator do
  destination File.expand_path("../../tmp", __FILE__)

  before do
    prepare_destination
    run_generator
  end

  it 'creates a test initializer' do
    assert_file 'config/initializers/wine_bouncer.rb', 'module WineBouncer'
  end
end

But when I run my tests, I get this error:

Any idea why I'm getting a NameError?

You can find a repo with the exact contents of the code here: https://github.com/whatasunnyday/wine_bouncer/tree/generator

Hey Steve, would it beneficial to update the README given the problem I had with the explicit require?

This little thing took me 2 hours before sorting it out.

Same for me, a note in the README would be helpful.
