Use Rails tasks instead:

lib/tasks/mytasks.rake

namespace :mytasks do

    desc "This is a Hello world task. All it does it say hello"
    task :hello => :environment do
      puts "Hello!"
    end
end

Then in the console you do:

rake mytasks:hello

One the quick temporary solution adds a new class method to your Model:

class Model
  def self.modify_db
    Model.find_each do |item| 
    end
  end
end

In console just type: Model.modify_db
