What was new in this chapter?
Installing, updating, and querying specific gem package files
The MVC pattern
Viewing your first Rails application
Generating Models and Controllers
index View used as the default View
Distinguishing instance methods from class methods with
HTML stub files for Views
With just that information, you could create some interesting applications that do a variety of dynamic tasks. However, the real power of Rails stems from its ability to access a database and manipulate content. That will be the focus of our next and final chapter.
