How to save associated object in Grails? - grails

Question

I am a grails beginner.
i have a 2domain class
class Employee {
String name
String department
static constraints = {
}
public String toString() {
name
}
}
class Address {
String line1
String line2
Employee employee
static belongsTo = Employee
static constraints = {
}
}
where Address belongs to Employee .. so i have given belongsTo association.
My Employee/create.gsp page takes input for fields specified in Employee and Address.
so on creation of employee , address must be get save automatically .
so what could be the save action in EmployeeController
i have tried some thing like this but did not work.
def save = {
def employeeInstance = new Employee(params)
def addressInstance = new Address(params)
if (employeeInstance.save(flush: true)) {
flash.message = "${message(code: 'default.created.message', args: [message(code: 'employee.label', default: 'Employee'), employeeInstance.id])}"
redirect(action: "show", id: employeeInstance.id)
}
else {
render(view: "create", model: [employeeInstance: employeeInstance])
}
}
how to save this associated model ?

Answer 1

Here you have a one-to-one relationsip - add an address property to the Employee class.
class Employee {
String name
String department
Address address
public String toString() {
name
}
}
Change your belongsTo of the Address like this:
class Address {
String line1
String line2
static belongsTo = [employee: Employee]
}
Now you could create an Employee like this:
def employeeInstance = new Employee(params)
employeeInstance.address = new Address(params)
if (employeeInstance.save(flush: true)) {
// your logic
}
Read the docs (one-to-one relationship) for further informations.
