API / Apache Grails Interview questions

What is scaffolding in Grails?

Scaffolding is Grails' feature for automatically generating a full working create/read/update/delete (CRUD) interface — controller actions and GSP views — for a domain class, based entirely on its properties and constraints, without a developer writing that boilerplate by hand.

It comes in two flavors: dynamic scaffolding generates the controller and views entirely at runtime, with nothing written to disk, ideal for quickly prototyping or exploring a domain model; static (generated) scaffolding writes actual controller and GSP files to the project via a CLI command, giving the developer real, editable source code to customize once the generated starting point needs to diverge from the default behavior.

Scaffolding is commonly used early in a project to get a working admin interface or demo instantly from just the domain model, and then gradually replaced or customized as the application's real requirements diverge from the generic CRUD pattern it produces.
