In this tutorial I explain Seedbank, a gem that I use regularly that helps keep the seeds in your project organised.

Seeding class

To help keep the seed files as clean as possible, I've made a class that stops seeds being added twice and also outputs to the user what has been added to the database:

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

Here is how to implement the class in your seeds:

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
