RESTful Grails: how do I include related entities in my XML? - rest

Question

Let's say I have a class called Store that has many Employees. My RESTful listXML method looks like this:
def listXML = {
render Store.list() as XML
}
And the result looks like this:
<stores>
<store id="1">
<name>My Store</name>
<employees>
<employee id="1" />
</employees>
</store>
</store>
My question is, how do I include all the data of each Employee class, so that my XML looks something like this?
<stores>
<store id="1">
<name>My Store</name>
<employees>
<employee id="1">
<name>John Smith</name>
<hireDate>2008-01-01</hireDate>
</employee>
</employees>
</store>
</store>

Answer 1

In your controller, you'll want to import the deep converter:
import grails.converters.deep.XML
You can read about it in the first couple of paragraphs of the Converters Reference.

Answer 2

As of Grails 1.1 you will be able to configure Grails to default to deeply serializing by including this in your grails-app/conf/Config.groovy:
grails.converters.xml.default.deep = true
1.1 also introduces named configurations for Converters. The deep converters will be deprecated and the named configuration "deep" should be used instead.
XML.use("deep") {
render model as XML
}
