ruby-on-rails – 用于测试的未定义方法`users’

发布时间：2020-12-17 02:55:52 所属栏目：百科来源：网络整理

导读：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 ActionController::TestCase # test "the truth" do # assert true # end

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 < ActionController::TestCase
  # test "the truth" do
  #   assert true
  # end

  test "should fetch facebook post" do
    sign_in users(:one)
    get(:save_posts_from_facebook_page,{'id'=>'my_id'},{'access_token'=>Rails.application.secrets.fb_access_token})
    assert_response :success
  end
end

test_helper.rb中：

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里：

# Read about fixtures at http://api.rubyonrails.org/classes/ActiveRecord/FixtureSet.html

one:
  email: hello@testing.com
  encrypted_password: <%= Devise.bcrypt(User,'password') %>
  links: 
  causes: 

two:
  email: MyString
  password: MyString
  links: 
  causes:

rake / Error的输出：

Run options: --seed 42684

# Running:

  1) Error:
PostsControllerTest#test_should_fetch_facebook_post:
NoMethodError: undefined method `users' for #<PostsControllerTest:0x000001042152f0>
    test/controllers/posts_controller_test.rb:9:in `block in <class:PostsControllerTest>'

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

解决方法

在test_helper.rb文件中,您需要添加fixture：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

一旦在test_helper.rb文件中添加该行,如上所示,您的测试将通过.

更新

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this answer,其中也说明了google group discussion.

我建议你使用factory_girl,它支持mongoid,非常棒.
