Controller Usage
A controller fulfills the C in the Model View Controller (MVC) pattern and is responsible for handling web requests. In Grails a controller is a class that ends in the convention "Controller" and lives in the grails-app/controllers
directory. A controller can be created with the create-controller command:grails create-controller hello
Or via your favourite IDE or text editor.class HelloController {
def world = {
render "Hello World!"
}
}
Each action in the controller is a callable block (for example the world
action above) that has access to a number of implicit variables and methods which are covered in this reference documentation.Refer to the user guide topic on Controllers for more information.
