Codecast: Getting Started with Rails 7 04: Model CRUD in the Console and Listing Articles
This is the 4th video in the Getting Started with Rails 7 series. In this video Mike explores the Rails console with the Article model and the ability to Create, Read, Update, and Destroy (CRUD) Article records in the console. After that he takes a quick look at the Rails database console, customizes some Rails fixtures, updates the controller test, and adds in the changes to the ArticlesController and index template to display a list of articles.
