Question

我在我的本地机器上运行它工作正常......但是当我上传到heroku时我错了

时收到500错误

设置控制器

class SettingsController＆lt; ApplicationController的 before_filter：confirm_logged_in

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

端

设置视图

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

＆lt;％end＆gt;

我检查heroku日志这是我得到的......任何想法
