Returning a list of objects (with contents) that "belongsTo" another object in Grails

Question

Currently I have set up a RESTful API to return 1 or more Book(s) that belongsTo an Author. Although this is what I want, it is not in the format I like it to be.

When I give an ID of 2 for the Author, I get the following response:

<author id="2">
    <author_name>Stephen</author_name>
    <books>
        <book id="2"/>
        <book id="3"/>
    </books>
</author>

Instead I would like a response that shows the contents of the books instead of a reference:

<list>
    <book id="2">
        <book_name>BookA</book_name>
        <book_year>2001</book_year>
    </book>
    <book id="3">
        <book_name>BookB</book_name>
        <book_year>2005</book_year>
    </book>
</list>

My contents of the controller that produces the first response is:

@Override
protected Book queryForResource(Serializable id) {
    def p = Author.id == params.AuthorId

    Book.where {
        id == id && p
    }.find()
}

Also is it possible to sort by book_year descending? Any help will be much appreciated.

This is because you are using default marshellers. Here is the answer for changing JSON response. You have to repeat this for XML. Everything else is same.
