I have a Ruby on Rails application. I changed my database and I want to deploy it to heroku.

How can I delete previous migrations on heroku and migrate my new database design?

I test using this code: heroku run db:migrate, but when I want to create a object from my new database design I got this error: We're sorry, but something went wrong

However, when I refresh my page it was created! What is wrong with it?

    Are you sure it’s your database? Try running heroku logs -t and running the request again. Then check your log and post your results. It might not even be a database problem.

    To erase your database run

    heroku pg:reset --db SHARED_DATABASE_URL

    or 

    heroku pg:reset --db SHARED_DATABASE

    then run

    heroku run rake db:migrate

    If all your migrations are correct then you should not experience the same problem.
