Do you think your code clean, useful and readable? I’m sure you’re wrong! Rails community’s invented many gems what are constantly analyzing your code and they give you to know about stuff what you should improve. Let me introduce some of these gems:

rails_best_practices

Have you heard about Bullet gem? Improve your SQL queries with Bullet The Bullet gem is designed to help you increase your application’s performance by reducing the number of queries it makes. It will watch your queries while you develop your application and notify you when you should add eager loading (N+1 queries). When you’re using eager loading that isn’t necessary and when you should use a counter cache. add it into a Gemfile

gem ‘bullet’, group: ‘development’

Append to config/environments/development.rb initializer with the following code:

config.after_initialize do Bullet.enable = true Bullet.alert = true Bullet.bullet_logger = true Bullet.console = true Bullet.growl = trueend
