Heroku Rails内部服务器错误

当我尝试在heroku上部署我的rails应用程序时,我收到了500内部服务器错误.它在我的本地机器上工作正常,所以我不确定这里有什么问题.似乎是家庭控制器上的"会话".这是我的日志:

这是我的home_controller.rb

class HomeController < ApplicationController
    before_filter :login_required

    def index
        @user = current_user
        @user.profile ||= Profile.new
    @profile = @user.profile
    end

end

它有我的路线设置的方式吗？或者是我的身份验证？(我正在使用Bort的restful身份验证)

您的应用似乎正在寻找会话表.

你运行了所有的迁移吗？

有时它可以帮助使用heroku db:push来确保您的数据库本地和远程相同.
