Useful in migrations

The most common usage pattern for this method is probably in a migration, when just after creating a table you want to populate it with some default values, eg:

class CreateJobLevels < ActiveRecord::Migration
def self.up
  create_table :job_levels do |t|
    t.integer :id
    t.string :name

    t.timestamps
  end

  JobLevel.reset_column_information
  %w{assistant executive manager director}.each do |type|
    JobLevel.create(:name => type)
  end
end

def self.down
  drop_table :job_levels
end
end
