【问题描述】：

我在运行 Rake 任务时遇到了 FactoryGirl 问题。

这是我在 Windows 7 笔记本电脑上的当前设置：

1) RubyMine 4.5 2) 导轨 3.2.8 3) 红宝石 1.9.3 4) PostgreSQL 9.1 5) rspec-rails 2.11.0 6) 水豚 1.1.2 7) factory_girl_rails 4.0 8) 应该

这是我的 spec_helper.rb 文件：

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

require 'factory_girl'

#Support for capybara
require 'capybara/rspec'
require 'capybara/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
  config.mock_with :rspec

  # 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

#spec for authentication
def login_user
  @user = FactoryGirl.create(:user)

  visit new_user_session_path
  fill_in "Email", :with=> @user.email
  fill_in "Password", :with=> @user.password

  click_button "Sign In"
end

这是我的 authentication_spec.rb：

require 'spec_helper'

describe "Sign Out link" do
  it "should sign you out when clicked" do
    login_user
    page.should have_content("Signed in as")
  end
end

这是我的跟踪错误消息：

我不确定我需要如何解决这个问题。

非常感谢任何帮助。

【问题讨论】：

:user 工厂在哪里定义？你确定它被包括在内？通常这会发生在spec_helper.rb

标签： ruby ruby-on-rails-3 rake factory-bot

【解决方案1】：

问题是因为您的 spec_helper.rb 曾经引用过 FactoryGirl.create(:users) -- 请注意复数 -- 而不是 FactoryGirl.create(:user)。如果您在问题中保存了spec_helper.rb，那么它将起作用。我认为它会显示您所说的错误的唯一情况是，如果未保存此文件。
