Join Kevin Skoglund for an in-depth discussion in this video Basic CRUD, part of Ruby on Rails 3 Essential Training.
Over the previous few chapters, we've learned how to work with databases…using Rails models.…Now we can apply that knowledge to adding the basic CRUD to our application.…Let's begin by reviewing the MVC architecture diagram again.…In the beginning, we learned how to work with controllers and views to create…dynamic pages and return them to the browser.…After that we shifted our focus and we learned to interact with the database by…creating models and associations.…We worked with those not from a browser, but via the Rails console.…Well, the bridge we need now is we need to learn how to work with our models…from the controller.…
