ruby - 割り当てられた変数を「ブレーク」削除しますか?

Question

最初はチャンピオンがハーマイオニーで、ブレイク後にチャンピオンがゼロになる理由がわかりません... ブレイクの使用に問題はありますか?

ここに私のコードがあります:

def pair(users_with_meeting, paired_users, ordered_keys,week)    

  ordered_keys.each do |key|    
    candidates = users_with_meeting[key] - paired_users  
    unless candidates.empty?  
      champion = candidates.first 
      puts "ok"
      puts champion.inspect.to_s   
      break    
    end     
  end   

  puts champion.inspect.to_s   

  if champion
    meetings.create! week: week, paired_user: champion
    champion.meetings.create! week: week, paired_user: self
  else
    []
  end

end

そして、これが私の端末に表示されるものです：

Run options: include {:locations=>{"./spec/models/user_spec.rb"=>[117]}}
ok    
#<User id: 1265, email: "Hermione.Granger@example.com", first_name: "Hermione", last_name: "Granger", uid: "Hermione.Granger@example.com", active: true, admin: false, created_at: "2013-09-15 18:09:16", updated_at: "2013-09-15 18:09:16", reset_date: "2013-04-22">
