Question

  Class Carro {
    String name
    String marca
    String matricula

    } 

    Class CarroMovel{

    String pro1
    String prop2
    String prop3

    Carro carro

    static hasMany = [ carros: Carro]

    }

---

 def save2 = {

                def carroInstance = new Carro()
                def carroMovelInstance = new CarroMovel()

                carroInstance.name = params.name
                carroInstance.marca = params.marca
                carroInstance.matricula = params.matricula

                carroMovelInstance.prop1 = params.carroMovel.prop1
                carroMovelInstance.prop2 = params.carroMovel.prop2
                carroMovelInstance.prop3 = params.carroMovel.prop3

                carroInstance.save()
                carroMovelInstance.carro = carroInstance
                carroMovelInstance.save()                 

            }

The CarroInstance is saving, but the carroMovelInstance isn’t. I cannot figure it out. Any help would be apreciated.

Answer 1

You probably have a validation error. Try calling validate() on it and inspecting the errors. Alternatively, try saving it with carroMovelInstance.save(failOnError: true) and you’ll get an exception if it doesn’t validate.
