Grails per-query one-to-one eager fetching

Let's say you have face and nose, and you want to get the nose based on a faceId.

The Grails 开发者_运维技巧user guide tells you how to use mapping = { fetch:join } in a domain class to eagerly fetch the nose in one query whenever you fetch the face.

But I don't want to eagerly fetch all the time. I just want to do on this particular case to use one query instead of two. Can this be done on a per-query basis? Is there some way to do something like: Face.get(faceId, [join:nose])?

Do you mean somthing link taht:

static fetchMode = [nose:'eager']

Update:

You can solve the problem with a criteria query. Here you can set the fetch mode in the query:

import org.hibernate.FetchMode as FM
    def c = MyDomain.createCriteria()
    def results = c.list {
        maxResults(10)
        firstResult(50)
        fetchMode("aRelationship", FM.EAGER)
    }
