I was creating some REST web services and I needed to map a URL like
“/api/1.0/recipes” to a controller called RecipesRestController. It took
me a while to work out how to generate a dynamic controller name from
the request path. The trick is not to use $controller, it doesn’t seem
to work, so instead I renamed it $aController.
class
UrlMappings {
static
mappings = {
"/$controller/$action?/$id?"
{
constraints {
// apply constraints here
}
}
"/"
(view:
"/index"
)
"500"
(view:
'/error'
)
"/api/1.0/$aController"
{
controller={
"${params.aController}Rest"
}
action=[GET:
"list"
, POST:
"save"
]
}
"/api/1.0/$aController/$id"
{
controller={
"${params.aController}Rest"
}
action=[GET:
"show"
, PUT:
"update"
, DELETE:
"delete"
]
}
}
}
OR
import org.codehaus.groovy.grails.commons.ApplicationHolder
class UrlMappings {
static mappings = {
for( controllerClass in ApplicationHolder.application.controllerClasses) {
// Admin Controllers first
if( controllerClass.name.startsWith("Admin")){
// note... fixes the case so that AdminUserController maps to /admin/user
"/admin/${controllerClass.name[5].toLowerCase() + controllerClass.name[6..-1]}/$action?/$id?" {
controller = "admin${controllerClass.name[5..-1]}".toString()
}
}
}
}
}
OR
"/admin/$controller/$action?/$id?"{
controller = {
def controllerName = (request.requestURI - request.contextPath).split('/')[2]
// or
//def controllerName = request.servletPath.split('/')[2]
"${controllerName}Admin"
}
}
