测试的未定义方法`users’

我正在尝试编写一个简单的测试，但是当我在Test函数中使用它时，我的应用程序没有检测到’users’关键字：

post_controller_test.rb ：

 require 'test_helper' class PostsControllerTest 'my_id'},{'access_token'=>Rails.application.secrets.fb_access_token}) assert_response :success end end 

test_helper.rb ：

 ENV['RAILS_ENV'] ||= 'test' require File.expand_path('../../config/environment', __FILE__) require 'rails/test_help' class ActiveSupport::TestCase include Devise::TestHelpers # Add more helper methods to be used by all tests here... end 

users.yml ：

 # Read about fixtures at http://api.rubyonrails.org/classes/ActiveRecord/FixtureSet.html one: email: [e-mail] encrypted_password:  links: causes: two: email: MyString password: MyString links: causes: 

rake / Error的输出：

 Run options: --seed 42684 # Running: E Finished in 0.010275s, 97.3279 runs/s, 0.0000 assertions/s. 1) Error: PostsControllerTest#test_should_fetch_facebook_post: NoMethodError: undefined method `users' for # test/controllers/posts_controller_test.rb:9:in `block in ' 1 runs, 0 assertions, 0 failures, 1 errors, 0 skips 

更新： 请注意，我正在使用MongoId。

当我将’fixtures：all’添加到我的test_helper.rb时，我得到：

耙

Answer 1

在test_helper.rb文件中，您需要添加fixtures :all ：

 class ActiveSupport::TestCase # Setup all fixtures in test/fixtures/*.yml for all tests in alphabetical order. fixtures :all # rest of the codes in this file end 

在test_helper.rb文件中添加该行后，如上所示，您的测试将通过。

正如Sergio Tulentsev在评论中提到的，Mongodb不支持交易，因此在您的情况下不能使用交易固定装置。 看一下这个答案 ， 该答案也说明了这个以及谷歌小组的讨论 。

我建议你使用factory_girl，它支持mongoid并且非常棒。
