Summary

In this chapter, we deep-dived into the Rails framework and learned about features such as Active Record associations, which are essential for any real-world application, and with six associations provided by Rails, working with models and databases becomes easier and more organized. We then learned about validations and the various options Rails provides. After that, we learned about scaffolding in Rails, which is a very powerful tool for rapid application development. Lastly, we learned about how to host our application on the World Wide Web with a popular hosting service called Heroku.

We have learned a lot in the last 12 chapters and we are confident that you will be excited to work with one of the most beautiful and powerful programming languages, Ruby (with the equally powerful Rails framework) – for your next software assignment.
