activerecord -3.1.11出错无法找到表（ActiveRecord :: Statement Invalid）
在将我的应用程序推送到heroku之前，我在生产模式下测试了我的应用程序，如果它处于开发模式，它可以正常工作，但在生产模式下我得到以下错误activerecord -3.1.11无法找到表格（ActiveRecord :: Statement无效） ）。
如何解决此错误？
我确信表’页’存在。

它在生产数据库中不存在，默认情况下不同。
你应该跑
RAILS_ENV=production bundle exec rake db:migrate
迁移生产数据库或编辑database.yml文件以将生产数据库设置为与开发数据库相同。
