запрос не работает в героку

Question

Я запускаю это на своей локальной машине, оно работает нормально ... но когда я загружаю в heroku Я получаю ошибку 500 что-то, когда не так

настройки контроллера

класс SettingsController

def company
  @company = User.company
  @user_id = session[:user_id]
  @user_name = session[:name]
  @companies = Company.where(:user_id => @user_id)
end

конец

---

просмотр настроек

<% @companies.each do |company| %>
  <div id="media">
    <span class="lop">    
        <%= image_tag company.logo.url (:small)  %>
    </span>

<% end> ​​

Я проверяю логи героку, вот что я получаю ... любые идеи
