ruby-on-rails-3 – FactoryGirl,为什么我已经注册或未初始化不变?

前端之家收集整理的这篇文章主要介绍了ruby-on-rails-3 – FactoryGirl,为什么我已经注册或未初始化不变?前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。
我正在尝试为我的模型课程做一个简单的测试,我写了这个工厂:
FactoryGirl.define do
  factory :course do
    name 'How to be happy ?'
    end
end

course_spec.rb:

require "rspec"
require 'factory_girl_rails'
describe "When a course is created" do

  it "can't be deleted if any student is enrolled to it" do
    FactoryGirl.find_definitions
    course = FactoryGirl.build(:course)

    student= Student.create!
    course.students << student
    course.destroy
    course.name.should !=nil
  end
end

但是,我达到了这条线

course = FactoryGirl.build(:course)

我收到错误

FactoryGirl::DuplicateDefinitionError: Factory already registered: course

如果我在工厂评论:课程定义,我得到:

NameError: uninitialized constant Course

有什么想法吗?

这是我的Gem Envioronment:

spec_helper.rb文件

require 'rubygems'
require 'spork'




    Spork.prefork do
      # Loading more in this block will cause your tests to run faster. However,# if you change any configuration or code from libraries loaded here,you'll
      # need to restart spork for it take effect.

      # Requires supporting ruby files with custom matchers and macros,etc,# in spec/support/ and its subdirectories.

      RSpec.configure do |config|
        # == Mock Framework

        # 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





    end

    Spork.each_run do
      # This code will be run each time you run your specs.
      FactoryGirl.factories.clear
      # either this if you have multiple files under 'spec/factories',# or just load the single file,such as 'spec/factories.rb'
      Dir.glob("#{::Rails.root}/spec/factories/*.rb").each do |file|
         load "#{file}"
      end

    end

解决方法

你试图删除这一行吗?
FactoryGirl.find_definitions

我正在使用Factory Girl(带有factory_girl_rails宝石)&应该使用3.1项目并且不必显式加载定义.
