Grails .save（）未保存关联的域

Question

I have a domain Guest which has a belongsTo association with Person and User domains as follows :

class Guest {

    static belongsTo = [
            person:Person,
            user : User // owner for guest
    ]


}

In my service GuestService.groovy , i am trying to update associated Person info associated with a given guest :

@Transactional
    def updateGuests(def guestArray) {

        guestArray.each { data ->

            User user = User.findById(data["userId"])
            Guest guest = Guest.findByIdAndUser(data["guestId"] , user)
            if( ! guest )
                throw new NotFoundException("Invalid input parameters")

            println(" email : " + guest.person.email + " new email " + data["email"])

            Person person = guest.person
            //person = Person.findById(person.id)

            person.email = data["email"]
            person.phoneNumber = data["phoneNumber"]

            person.save(flush:true)
            //guest.save(flush: true)
        }
    }

I am unable to update Person info and i don't receive any errors too. I Debugged the code and all the values are present till exit of the debug point .I searched on internet and other related questions on this stack but no question is related to this kind of problem .

Answer 1

Have you tried person.save(flush: true, failOnError: true) ?

It should overwrite a default behavior of returning null on save error and return exception instead.
