Question

我很惭愧提出这个问题，但是我找不到我的错误，我再一次从Michael Hartl那里做导轨教程，因为我第一次无法做正确的TDD，无论如何我有设法完成每一项测试，但只有一次！问题是我在rails'控制台上手动测试它并且它工作了，我尝试用rake db:reset和rake test:prepare重置数据库，显然重新填充数据库rake db:populate确定，直接到关键......我有以下测试

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

根据我的说法，一切正常，我在rails console上手动测试，但是当使用rpsec spec/models/user_spec.rb运行规范时，会出现以下错误 Failures:

Answer 1

您需要更改feed文件

中的user.rb方法

这

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

到

def feed
    Micropost.from_users_followed_by(self)
end

以及将方法self.from_users_followed_by添加到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
