How to reset PG Database on Heroku?

• Step 1: heroku restart
• Step 2: heroku pg:reset DATABASE (no need to change the DATABASE)
• Step 3: heroku run rake db:migrate
• Step 4: heroku run rake db:seed (if you have seed)

One liner

heroku restart; heroku pg:reset DATABASE --confirm APP-NAME; heroku run rake db:migrate

Note that Heroku Config is found in /.git/config
** Make sure you have setup your git properly before pushing to Heroku **

Pre-conditions for app on Heroku

• Database must be Postgres: gem 'pg'
• Heroku uses unicorn, so you need: gem 'unicorn'
• Heroku needs this gem too: gem 'rails_12factor', group: :production
• Add ruby '2.0.0' to the top of your Gemfile
• Remove gem 'sqlite3' from your Gemfile
• Setup Procfile as per https://devcenter.heroku.com/articles/getting-started-with-rails4#webserver
