(Quick Reference)



To redirect flow from one action to the next using an HTTP redirect.


redirect(action: "show")

redirect(controller: "book", action: "list")

redirect(controller: "book", action: "list", namespace: "publishing")

redirect(controller: "book", action: "list", plugin: "publishingUtils")

redirect(action: "show", id: 4, params: [author: "Stephen King"])

redirect(controller: "book", action: "show", fragment: "profile")

redirect(uri: "book/list")

redirect(url: "http://www.blogjava.net/BlueSUN")


Redirects the current action to another action, optionally passing parameters and/or errors. When issuing a redirect from a namespaced controller, the namespace for the target controller is implied to be that of the controller initiating the redirect. To issue a redirect from a namespaced controller to a controller that is not in a namespace, the namespace must be explicitly specified with a value of null as shown below.

class SomeController {
    static namespace = 'someNamespace'

    def index() {
        // issue a redirect to PersonController which does not define a namespace
        redirect action: 'list', controller: 'person', namespace: null
