Scaffolding in web application frameworks

Scaffolding is a meta-programming method of building database-backed software applications. It is a technique that allows a programmer to qickly generate a skeleton interface that allows the user to perform basic CRUD ( Create Read Update Delete) operations on the application's database. The auto-generated interface can then me modified to perform more powerful tasks.


Why was dynamic scaffolding removed in Rails 2?

Dynamic Scaffolding of Rails 1.x was replaced by a generator of scaffolds in Rails 2.

David Heinemeier Hansson responding to a new rails developer on a Ruby forum said "Dynamic Scaffolding didn't really help people learn about Rails or give them a way to modify the generated interface, so we killed it.". In dynamic scaffolding when the line scaffold :model_name is added to the controller ruby automatically generates the appropriate interfaces at run time. Since, scaffolding is implemented at run time the programmer cannot easily modify and customize the interfaces.Hence, dynamic scaffolding was removed in Rails 2.
