Week 7: Rails Passion Course

1. Week 7: Scaffolding (Scaffolding is a way to quickly put an Active Record class online by providing a series of standardized actions for listing, showing, creating, updating, and destroying objects of the class. These standardized actions come with both controller logic and default templates that through introspection already know which fields to display and which input types to use. // Topics covered: What is scaffolding?, Controller (that is generated through scaffolding), Templates (that are generated through scaffolding))
