The methods I use with seedbank to easily add new seeds with a nice message.

seeds.rb

class Seeds
  def self.add model, attrs
    object = model.find_or_initialize_by(attrs)

    if object.new_record? && object.save
      puts "#{object}"
    end
  end
end

users.seeds.rb

after :farms do
  puts 'Adding Users:'

  farm = Farm.find_by name: 'McCain'
  Seeds.add User, full_name: 'Mr McCain', is_manager: true, farm: farm
end
