Error with activerecord -3.1.11 Could not find table (ActiveRecord::Statement Invalid)

Question

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.

Answer 1

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.
