(Quick Reference)



Generates a controller and associated unit test for the given domain class


grails generate-controller
grails generate-controller org.bookstore.Book
grails generate-controller "*"


Grails supports a feature known as static scaffolding which involves the generation of a CRUD (Create/Read/Update/Delete) interface for a given domain class. Once generated, the controller and its views can be modified by you but they won’t automatically update when you change the domain class.

The generate-controller command generates just the controller (and associated unit test) that implements CRUD for the given domain class. The argument is optional, but if you don’t include it the command will ask you for the name of the domain class to scaffold. So for a domain class org.bookstore.Book, this command will generate the controller BookController.groovy in grails-app/controllers/org/bookstore.


grails generate-controller <<domain class name>>


  • domain class name - Either a domain class name (case-sensitive) or a wildcard (\*). If you specify the wildcard controllers will be generated for all domain classes.


  • force - Whether to overwrite existing files
