Introduction to Ruby on Rails
Rails is a framework which runs on the Ruby programming language and is used to rapidly create web applications. Many startups use Rails because they can rapidly create a full application from scratch. Not only is Rails a great way to save hours of coding time, it’s also a great way to learn advanced web development. When you learn Rails, you’ll learn the tips and techniques that professional programmers use to create real world web applications.
Upon completion of this course, you will be able to:
- Use code generation to get your application up-and-running in minutes rather than hours
- Model complex business data with database relationships
- Add login security to your application
- Manage your web interface efficiently with partial templates and layouts
- Add search to your application with database finders
You will learn how to build a secure multi-user task management application and create your own photo-posting web site. All you need is a browser and an Internet connection; everything else is provided by the O’Reilly School of Technology.
