How to make some URL mappings depending on the environment?

Question

When getting an HTTP status code 500, I want to display 2 different pages according to the running environment.

In development mode, I want to display a stackStrace page (like the default Grails 500 error page) and in production mode, I want to display a formal "internal error" page.

Is it possible and how can I do that ?

You can do environment specific mappings within UrlMappings.groovy

grails.util.GrailsUtil to the rescue

Its not pretty, but I think it will solve your issue

E.g

import grails.util.GrailsUtil

class UrlMappings {
    static mappings = {


        if(GrailsUtil.getEnvironment() == "development") {

             "/$controller/$action?/$id?"{
                constraints {
                    // apply constraints here
                }
            }

            "/"(view:"/devIndex")
            "500"(view:'/error')
        }

        if(GrailsUtil.getEnvironment() == "test") {
            "/$controller/$action?/$id?"{
                constraints {
                    // apply constraints here
                }
            }

            "/"(view:"/testIndex")
            "500"(view:'/error')

        }



        if(GrailsUtil.getEnvironment() == "production") {
            "/$controller/$action?/$id?"{
                constraints {
                    // apply constraints here
                }
            }

            "/"(view:"/prodIndex")
            "500"(view:'/error')

        }
    }
}
