API / Apache Grails Interview questions

What is the difference between static and dynamic scaffolding in Grails?

Both generate a working CRUD interface from a domain class, but they differ in whether that generated code is written to disk as real, editable source files, or produced purely in memory at request time.

Dynamic scaffoldingStatic (generated) scaffolding
No files written to the projectReal controller and GSP files generated via CLI command
Generated fresh at runtime on each requestFixed once generated, until manually edited
Great for quick prototyping and demosGreat once the generated behavior needs customization
No source to review or version-controlOrdinary source files, reviewable and version-controlled like any other code

A common workflow is starting with dynamic scaffolding to get an instant working interface while a domain model is still being iterated on, then switching to static scaffolding once the model stabilizes and the generated controller/views need real customization beyond what the generic CRUD pattern produces on its own.

Which type of scaffolding produces real, editable source files that can be version-controlled?
What is a common reason to switch from dynamic to static scaffolding partway through a project?
