Reading out all actions in a Grails-Controller

Question

I need to read out all available actions from any controller in my web-app. The reason for this is an authorization system where I need to give users a list of allowed actio

Answer 1

Grails does not support a straightforward way to do this. However, I was able to put together a puzzle from available grails methods and have come to this solution:

def actions = new HashSet()
def controllerClass = grailsApplication.getArtefactInfo(ControllerArtefactHandler.TYPE)
                         .getGrailsClassByLogicalPropertyName(controllerName)
for (String uri : controllerClass.uris ) {
    actions.add(controllerClass.getMethodActionName(uri) )
}

Variables grailsApplication and controllerName are injected by grails. As controller itself does not have necessary methods, this code retrieves its controllerClass (see GrailsControllerClass), which has what we need: property uris and method getMethodActionName
