Rails hack for using databases running in a virtual machine

remote.rake

# Rails only allows databases local to your machine. If you run your databases in a VM
# (and you should), then you need to add this

namespace :db do
  def local_database?(config, &block)
    if config['host'].in?(['127.0.0.1', 'localhost', '172.16.12.102']) || config['host'].blank?
      yield
    else
      $stderr.puts "This task only modifies local databases. #{config['database']} is on a remote host."
    end
  end
end
