RailsTutorial rspec測試失敗

我很慚愧地提出這個問題，但我找不到我的錯誤，我再次從邁克爾哈特爾那裏學習rails教程，因爲第一次我無法做到正確TDD，無論如何，我已經成功地進行了每一個測試，但只有一個！事情是，我在軌道上的控制檯手動測試它，它的工作原理，我試圖重置數據庫與rake db:reset和rake test:prepare和明顯重新填充數據庫rake db:populate好吧，直接點...我有以下測試RailsTutorial rspec測試失敗

describe "status" do 
     let(:unfollowed_posts) do 
     FactoryGirl.create(:micropost, user: FactoryGirl.create(:user)) 
     end 
     let(:followed_user) { FactoryGirl.create(:user) } 

     before do 
     @user.follow!(followed_user) 
     3.times { followed_user.microposts.create!(content: "Lorem Ipsum") } 
     end 

     its (:feed) { should include(newer_micropost) } 
     its (:feed) { should include(older_micropost) } 
     its (:feed) { should_not include(unfollowed_posts) } 
     its (:feed) do 
     followed_user.microposts.each do |micropost| 
      should include(micropost) 
     end 
     end 
    end

根據我，一切都很好，我手動測試它rails console，但是與乳寧rpsec spec/models/user_spec.rb規範時，出現以下錯誤 Failures:

</code>

I don't understand why the user_id is changed if the code 3.times { followed_user.microposts.create!(content: "Lorem Ipsum") }不觸及followed_user都來了，所以......這是我的現在頭痛，爲什麼會發生這種情況？這是rspec的一個虛假行爲，預先感謝，併爲這個沉悶的問題提供。

你正在使用哪個版本的Rails，以及你在教程中的位置是什麼？ – pawel7318

我目前使用rails 4.0.4和ruby 2.0.0，使用postgresql作爲數據庫，這是最後一章[http://www.railstutorial.org/book/following_users#sec-motivation_and_strategy]代碼示例是11.41中列出的那個 – Coronellx

你需要改變你feed方法user.rb文件

從

def feed 
    Micropost.where("user_id = ?", user) 
end

到

def feed 
    Micropost.from_users_followed_by(self) 
end

，以及添加方法self.from_users_followed_by您micropost.rb文件

def self.from_users_followed_by(user) 
    followed_user_ids = "SELECT followed_id FROM relationships WHERE follower_id = :user_id" 
    where("user_id IN (#{followed_user_ids}) or user_id = :user_id", user_id: user.id) 
end
