Factory already registered: user (FactoryGirl::DuplicateDefinitionError)

Question

Description of problem: - I've setup factory_girl_rails however whenever I try and load a factory it's trying to load it multiple times.

Environment: - rails (3.2.1) - factory_girl (2.5.2) - factory_girl_rails (1.6.0) - ruby-1.9.3-p0 [ x86_64 ]  > rake spec --trace ** Execute environment -- Creating User Factory -- Creating User Factory rake aborted! Factory already registered: user 

The only other thing I've changed is: /config/initializers/generator.rb

Rails.application.config.generators do |g|   g.test_framework = :rspec   g.fixture_replacement :factory_girl end 

GEMFILE

gem 'rails', '3.2.1'  # Bundle edge Rails instead: # gem 'rails', :git => 'git://github.com/rails/rails.git'  group :assets do   gem 'sass-rails',   '~> 3.2.3'   gem 'coffee-rails', '~> 3.2.1'    gem 'uglifier', '>= 1.0.3' end  gem 'jquery-rails' gem 'devise' gem 'haml-rails'  group :development do   gem 'hpricot'   gem 'ruby_parser'   gem "rspec-rails" end  group :test do   gem "rspec"   gem 'factory_girl_rails' end  gem 'refinerycms-core',       :git => 'git://github.com/resolve/refinerycms.git' gem 'refinerycms-dashboard',  :git => 'git://github.com/resolve/refinerycms.git' gem 'refinerycms-images',     :git => 'git://github.com/resolve/refinerycms.git' gem 'refinerycms-pages',      :git => 'git://github.com/resolve/refinerycms.git' gem 'refinerycms-resources',  :git => 'git://github.com/resolve/refinerycms.git' gem 'refinerycms-settings',   :git => 'git://github.com/resolve/refinerycms.git'  group :development, :test do   gem 'refinerycms-testing',  :git => 'git://github.com/resolve/refinerycms.git' end  gem 'refinerycms-inventories', :path => 'vendor/engines'  FactoryGirl.define do   factory :role do     title "MyString"   end end 

This seems to be a compatibility/environment issue that I can't seem to figure out. Any suggestions?

EDIT: here's my spec/spec_helper.rb:

ENV["RAILS_ENV"] ||= 'test' require File.expand_path("../../config/environment", __FILE__) require 'rspec/rails' require 'rspec/autorun' #require 'factory_girl_rails'  # Requires supporting ruby files with custom matchers and macros, etc, # in spec/support/ and its subdirectories. Dir[Rails.root.join("spec/support/**/*.rb")].each {|f| require f}  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 end

The gem factory_girl_rails should be required in the spec_helper.rb rather than the gemfile - it is possible that you are requiring FactoryGirl twice which is why you are getting the duplicate.

Try this in your gem file:

group :test do   gem "rspec"   gem 'factory_girl_rails', :require => false end 

Then make sure that factory girl is required in the spec_helper with:

require 'factory_girl_rails' 

By the way - you don't need both rspec and rpsec-rails in your gemfile. You can replace both with the following:

group :development, :test do   gem 'rspec-rails' end 

You need rspec in both groups so that the rake tasks will work in development and the core testing will work in test.
