Question

我正在关注Rails教程并刚刚完成第11章。在localhost上没有错误，但在heroku上没有错误。 heroku日志（如下所示）说“关系'微博'不存在”后跟一些sql。鉴于localhost运行良好，我不知道该怎么办。有什么想法吗？

这是pages_controller.rb：

class PagesController < ApplicationController

  def home
    @title = "Home"
    if signed_in?
      @micropost = Micropost.new 
      @feed_items = current_user.feed.paginate(:page => params[:page])
    end
  end

  def contact
    @title = "Contact"
  end

  def about
    @title = "About"
  end

  def help
    @title = "Help"
  end
end

好的......最愚蠢的问题。我正在玩新手卡....忘记了“heroku rake db：migrate”。一切都很好。
