Is there a 'contains' functionality on a collection property of a domain object for createCriteria?

createcriteria, grails

Solution

Try this:

def l = c.list (max: maxVar, offset: offsetVar) {
    users {
        idEq(thisUser.id)
    }
}

Problem

I have an Auction domain object and a User domain object. An Auction `hasMany` Users. What I'd like to do, using `createCriteria`, is something like this: ``` def c = Auction.createCriteria() def l = c.list (max: maxVar, offset: offsetVar) { contains("users", thisUser) } ``` Though, `contains` is not in the list of acceptable nodes: createCriteria description page. Is there any way to implement this functionality? To be clear, is there a way to have the criteria be that a specified User object is contained within a collection property of the Auction?
