Gerneric url mapping for restful resources in grails

I have configured some restful resources in grails like this

"/book/$id?"(resource:"book")
"/author/$id?"(resource:"author")

But I want to to this more generic like

"/$controller/$id?"(resource: controller)

which doesn't work... (getting 404)

How can i configure a generic url mapping for restful resources in grails?

It would seem that the "resource" portion of the mapping is evaluated on startup, not on execution of the actual request (a guess from playing around with this). Therefore, I think you need to "preload" the set of UrlMappings you want dynamically based on the Domain classes available on application startup. Something like this might do the trick:

class UrlMappings {
static mappings = {
        ApplicationHolder.application.getArtefacts('Domain').each { GrailsClass cl ->
           "/${cl.propertyName}/$id?"(resource: cl.propertyName )            
        } ...

The correct mapping for your needs depends entirely on what you are trying to achieve (which can't be determined from the question).

Consider a generic mapping:

"/$controller/$action?/$id?"{}

This will map the first part of the URL to a controller of the same name, the second part to an action of that controller and the third part to what should be a unique identifier for a domain class instance.

Examples that work with this mapping:

/book/show/2

Controller: bookController
Action: show
id: 2

This will call the show action of the book controller.
params.id will be 2.

The intention implied in the URL is to show relevant details for a book object 
with an id of 2.

/question/update/6

Controller: questionController
Action: update
id: 6

This will call the update action of the question controller.
params.id will be 6.

The intention implied in the URL is to update the details for a question
object with an id of 6.
