In Grails, how do I get the discriminator value?

I have a class like this:

class Apple extends Fruit {
    static mapping = {
        discriminator "AppleType"
    }
}

Is there any way to get this discriminator value in the controller/view?

You can check the mapping of your domain class with the Mapping class. Example:

def mapping = GrailsDomainBinder.getMapping(Apple)
println mapping.discriminator
