**Course Title:** Ruby Programming: From Basics to Advanced Techniques **Section Title:** Final Project and Review **Topic:** Work on final projects that integrate concepts learned throughout the course.(Lab topic) **Objective:** In this lab, you will apply the concepts learned throughout the course to develop a comprehensive Ruby project. This project will help you reinforce your understanding of Ruby fundamentals, object-oriented programming, data structures, file handling, exception management, web development with Ruby on Rails, and testing. **Instructions:** 1. **Choose a Project Idea:** Select a project idea that interests you and integrates various concepts learned throughout the course. Some examples of project ideas include: * A command-line tool for managing a personal library * A web application for tracking expenses * A game implementation using Ruby and Rails * A chatbot using natural language processing 2. **Design and Plan:** Create a detailed design and plan for your project. Break down your project into smaller tasks and identify the required Ruby concepts and techniques. 3. **Implement the Project:** Implement your project using Ruby. Ensure that you apply the concepts learned throughout the course, including object-oriented programming, data structures, file handling, exception management, and testing. 4. **Use Ruby on Rails:** If your project involves web development, use Ruby on Rails to create the application. Implement models, views, and controllers as required. 5. **Test and Debug:** Write tests for your project using RSpec and implement test-driven development (TDD) principles. Debug your project to ensure it works as expected. 6. **Present Your Project:** Prepare a presentation to showcase your final project. Explain the design, implementation, and testing of your project. **Resources:** * [Ruby Documentation](https://ruby-doc.org/) * [Rails Documentation](https://guides.rubyonrails.org/) * [RSpec Documentation](https://rspec.info/documentation/) **Tips and Best Practices:** * Follow best practices for coding standards and commit messages * Use version control with Git to manage your project * Implement testing and debugging techniques to ensure your project is reliable * Use online resources and communities for help and guidance **Example Project:** To get you started, let's consider an example project - a command-line tool for managing a personal library. The tool will allow users to add, remove, and list books. ```ruby # library.rb class Book attr_accessor :title, :author, :year def initialize(title, author, year) @title = title @author = author @year = year end end class Library def initialize @books = [] end def add_book(title, author, year) @books << Book.new(title, author, year) end def remove_book(title) @books.delete_if { |book| book.title == title } end def list_books @books.each do |book| puts "#{book.title} by #{book.author} (#{book.year})" end end end library = Library.new while true puts "1. Add book" puts "2. Remove book" puts "3. List books" puts "4. Quit" choice = gets.chomp case choice when "1" puts "Enter book title: " title = gets.chomp puts "Enter book author: " author = gets.chomp puts "Enter book year: " year = gets.chomp library.add_book(title, author, year) when "2" puts "Enter book title to remove: " title = gets.chomp library.remove_book(title) when "3" library.list_books when "4" break else puts "Invalid choice. Please try again." end end ``` **Conclusion:** In this lab, you applied the concepts learned throughout the course to develop a comprehensive Ruby project. You designed and planned your project, implemented it using Ruby, and tested and debugged it using RSpec. You also used Ruby on Rails for web development and implemented models, views, and controllers as required. **Additional Help:** If you have any questions or need help with your project, please leave a comment below. **Leave a Comment:** Please use the comment section below to ask questions, share your project experiences, or provide feedback on the course.
