解决方案

对了，你的表存在，但可能只是在开发数据库。它并不在生产数据库，它是由缺省不同存在。

您应该​​运行

  RAILS_ENV =产品包的exec耙分贝：迁移
 

要迁移生产数据库或编辑的database.yml 文件来设置你的生产数据库是一样的开发数据库。

Before push my app to heroku, I tested my app in production mode, it works perfectly if its in the development mode, but in production mode I'm getting following error activerecord -3.1.11 Could not find table (ActiveRecord::Statement Invalid).

How to fix this error?

I'm sure that table 'pages' exists.

解决方案

Right, your table exists, but probably only in development database. It doesn't exist in production database, which is different by default.

You should either run

RAILS_ENV=production bundle exec rake db:migrate

to migrate your production database or edit database.yml file to set your production database to be the same as development database.
