Showing TPCH discriminator on list view

[ThomasBecker]

Hi all,

I have a domain object with some subclasses. I'm using Table Per Class Hirarchy and have a customized discriminator column and values for the subclasses.

Parent contains:

	static mapping = {
		tablePerHierarchy true
		discriminator column:"content_type", value: "basic asset"
	}

subclasses contain:

	static mapping = {
		discriminator value: "slide"
	}

Which works fine and is what I want. However I have a "list" view for the base class which shows all object instances of the parent and any subclass. On this list view I'd like to show a column with the discriminator value I defined in each subclass. I tried several hacks to access it and failed miserably so far. I tried adding fields with the same column as the discriminator and such nasty things.

Is there any way to access the discriminator on a domain object instance? Right now I'm using the class property instead, but that contains package information I don't want to have on the view.

Cheers,
Thomas

Some possible solutions on the Hibernate forum. There are no short cuts from Grails as far as I know.

As I have the convention classname = discriminator name in my domain objects, I'm using now class.getSimpleName() to display the discriminator in JSON.

Sorry, that I didn't update this thread. And thx for the hint.
