Description

Hi,

Please find discussion here http://grails.1312388.n4.nabble.com/Mongodb-RC4-and-Grails-2-0-referenced-objects-td4513464.html
In two words - It would be great to have direct link support along with the DBRef support - so saving the id of the referenced object and loading it during the selection from database.

Thanks in advance.

Regards,
Nune

I was interested to see this implemented, but I think there may still be a problem. Querying for an entity by an association doesn't appear to work if you set "reference:false".

Given the following code:
class Person {
ObjectId id
Address address
static constraints =

{ address reference: false }

}

class Address

{ ObjectId id String address }

The document in mongo looks correct when you save data like this:

Person(address: new Address(address: "123")).save()

However queries by association will not work (they will work if you rever to using DbRef):

def myAddress = Address.findById(new ObjectId("4f9839c4300478722548c2d9"))
Person.findByAddress(myAddress))

Any ideas?
