You have to check which version of ActiveRecord you are using. According to your command rake db:migrate you are still on Ruby on Rails 4.2 or earlier.

Rails 5 has redirect_back, instead of redirect_to :back. It was changed as it used to raise an exception when request’s HTTP_REFERER was not present. So use this: redirect_back fallback_location: root_path You can change root_path to something else as per your requirements.
Here are some one-liner alternatives: # Ruby 2.1+ name_to_code = countries.map{ |c| [c.name,c.code] }.to_h # Ruby 1.8.7+ name_to_code = Hash[ countries.map{ |c| [c.name,c.code] } ] # Ruby 1.8.6+ name_to_code = Hash[ *countries.map{ |c| [c.name,c.code] }.flatten ] # Ruby 1.9+ name_to_code = {}.tap{ |h| countries.each{ |c| h[c.name] = c.code } } # Ruby 1.9+ name_to_code = … Read more
