Heroku Checklist

To enable features such as static asset serving and logging on Heroku please add rails_12factor gem to your Gemfile.

# Gemfile
gem 'rails_12factor', group: :production

You should be running the same version of Ruby on Heroku that you're running locally.

Verify by checking your Ruby version locally

$ ruby -v

Now ensure you're Gemfile has a versioned number of Ruby

# Gemfile
ruby "2.1.1"

If you're using a database be sure to migrate it and seed the db on Heroku

$ heroku run rake db:migrate

You can update your seeds.rb file to clear out any previous data

# seeds.rb
User.delete_all  # clears out all previous entries in users
User.create(name: "admin", password: "1234", password_confirmation: "1234", is_admin: true)

then...

$ heroku run rake db:seed

Add any environmental variables you're using

$  heroku config:set KEY=value

you can do heroku run rake db:migrate, which will re-migrate the tables without the data, then heroku run rake:db seed
