Hey everyone,

For a long time I've been writing boilerplate classes that have basically the same structure of initialization:

class UserRegistrationForm  
  def initialize(access_code)
    @access_code = access_code
  end

require "rails_helper"

RSpec.describe PokemonsController do
  describe "GET #index" do
    it "renders the index template" do
      get :index
      expect(response.status).to eq(200)
      expect(response).to render_template('index)
    end
  end

### Rails app generator template. Run it:
### rails new _app_name_ -m https://gist.githubusercontent.com/DamirSvrtan/28a28e50d639b9445bbc/raw/app_template.rb

remove_file "README.rdoc"
create_file "README.md", "Development: run ./bin/setup"
run 'mv app/assets/stylesheets/application.css app/assets/stylesheets/application.scss'

database_type = ask("Do you want to use postgres or mysql?", limited_to: ["pg", "mysql"])

adapter = if database_type == 'pg'

  echo_length=${#1}
  stars=""
  star_length=$(($echo_length+8))
  for i in $(seq 1 $star_length); do
    stars="$stars*"
  done
  echo "\n"; echo "$stars"; echo "*** $1 ***"; echo "$stars"; echo "\n"
};
