uninitialized constant ActionController::Base

[terenceponce]

I'm new to Rails engines and this gem and I'm having this problem when I'm trying to access the dummy app in localhost:9292:

NameError: uninitialized constant ActionController::Base

Here's my config.ru:

require 'rubygems'
require 'bundler'

Bundler.require :default, :test

Combustion.initialize!
run Combustion::Application

and here's the gemspec file:

$:.push File.expand_path("../lib", __FILE__)

# Maintain your gem's version:
require "saasify/version"

# Describe your gem and declare its dependencies:
Gem::Specification.new do |s|
  s.name        = "saasify"
  s.version     = Saasify::VERSION
  s.authors     = ["Eumir Gaspar and Terence Ponce"]
  s.email       = ["dev+eumir+terence@aelogica.com"]
  s.homepage    = "http://example.com"
  s.description = "Saasify"

  s.files = Dir["{app,config,db,lib}/**/*", "MIT-LICENSE", "Rakefile", "README.rdoc"]
  s.test_files = Dir["test/**/*"]

  s.add_dependency "rails", "~> 4.0.0"
  s.add_dependency 'devise', '~> 3.0.0'
  s.add_dependency 'rails_admin', '~> 0.5.0'
  s.add_dependency 'rocket_pants', '~> 1.0'
  s.add_dependency 'money-rails', '~> 0.8.1'

  s.add_development_dependency 'rspec-rails', '~> 2.0'
  s.add_development_dependency 'combustion', '~> 0.5.1'
  s.add_development_dependency 'mysql2'
  s.add_development_dependency 'factory_girl_rails'
  s.add_development_dependency 'database_cleaner'
  s.add_development_dependency 'vcr'
  s.add_development_dependency 'webmock', '~> 1.11.0'
end

Here's my spec_helper.rb:

# This file is copied to spec/ when you run 'rails generate rspec:install'
ENV["RAILS_ENV"] ||= 'test'
require File.expand_path("../dummy/config/environment", __FILE__)
require 'bundler/setup'
require 'combustion'

Combustion.path = 'spec/dummy'
Combustion.initialize! :active_record, :action_controller, :action_view, :sprockets

require 'rspec/rails'
require 'rspec/autorun'

ENGINE_RAILS_ROOT = File.join(File.dirname(__FILE__), '../')

# Requires supporting ruby files with custom matchers and macros, etc,
# in spec/support/ and its subdirectories.
Dir[Rails.root.join(ENGINE_RAILS_ROOT, "spec/support/**/*.rb")].each { |f| require f }

# Checks for pending migrations before tests are run.
# If you are not using ActiveRecord, you can remove this line.
ActiveRecord::Migration.check_pending! if defined?(ActiveRecord::Migration)

RSpec.configure do |config|
  # ## Mock Framework
  #
  # If you prefer to use mocha, flexmock or RR, uncomment the appropriate line:
  #
  # config.mock_with :mocha
  # config.mock_with :flexmock
  # config.mock_with :rr

  # Remove this line if you're not using ActiveRecord or ActiveRecord fixtures
  config.fixture_path = "#{Rails.root}/spec/fixtures"

  # If you're not using ActiveRecord, or you'd prefer not to run each of your
  # examples within a transaction, remove the following line or assign false
  # instead of true.
  config.use_transactional_fixtures = true

  # If true, the base class of anonymous controllers will be inferred
  # automatically. This will be the default behavior in future versions of
  # rspec-rails.
  config.infer_base_class_for_anonymous_controllers = false

  # Run specs in random order to surface order dependencies. If you find an
  # order dependency and want to debug it, you can fix the order by providing
  # the seed, which is printed after each run.
  #     --seed 1234
  config.order = "random"
end

I followed the README as well as #27 and I still can't make it work on the browser. Did I miss anything here?

I encountered the same issue here.

Fixed it by changing the

Combustion.initialize!

to

Combustion.initialize! :active_record, :action_controller, :action_view, :sprockets

in config.ru. As you did, I additionally followed #27, which is still neccessary.

Thanks for picking that up @taetschgring - I've just pushed a tweak for the config.ru template and README, so that'll be fixed in future releases.
