####"Ruby on Rails Tutorial": 1. Book: [Ruby on Rails Tutorial: Learn Web Development with Rails](https://www.railstutorial.org/book/frontmatter) 2. Github: [railstutorial](https://github.com/railstutorial)/**[sample_app_rails_4](https://github.com/railstutorial/sample_app_rails_4)**
####Why I start this project (rails_sample_app_polen)? 1. In order to learn Ruby on Rails 2. There are some imperfections in sample_app_rails_4 : i>. In Gemfile: some packages's version are too low (including rails) ii>. Not contain "Account activation function"(Chapter10) in code iii>. Not contain test code
