How to access properties of a command object from another command object? - grails

Question

I am currently working on a grails application. I have two command objects (AccountInfoCommand and EducInfoCommand) in a controller. On my EducInfoCommand, I wanted to check if the yearGraduated property is earlier than the set birthDate(a property of AccountInfoCommand) on its validator constraints. How will I do that?
This is my code for my AccountInfoCommand:
class AccountDetailsCommand implements java.io.Serializable {
String username
String password
String confirmPassword
String emailAddress
Date birthDate
}
This is my code for EducInfoCommand:
class EducInfoCommand implements java.io.Serializable {
Integer graduated
EducationLevel educationLevel
String schoolName
String yearGraduated
String honorsReceived
}
static constraints = {
yearGraduated nullable: false, maxSize:4, blank: false, matches: /([0-9]*)/,
validator: {
Date.parse('yyyy',it) <= new Date() ? true : false
}
}
Please help!
Thanks!

Answer 1

You need some reference to which AccountDetails the EducInfo is for. For example, if you added a username field to the EducInfoCommand you could look up the account details from that (assuming there is an AccountDetails gorm object which is similar to the command object):
class EducInfoCommand implements java.io.Serializable {
String yearGraduated
String username
// ...
}
static constraints = {
yearGraduated nullable: false, maxSize:4, blank: false, matches: /([0-9]*)/,
validator: { val, obj ->
Date.parse('yyyy',val) > AccountDetails.findByUsername(obj.username).birthDate
}
}
