Question

I’m trying to add a reference from the default Spring Security user domain class to another class which should hold additional user info.

class User {
    transient springSecurityService

    String username
    String password
    boolean enabled
    boolean accountExpired
    boolean accountLocked
    boolean passwordExpired

    Profile profile
      ...

…and…

class Profile {
    static constraints = {
    }

    static belongsTo = [user : User]

    String firstName
    String lastName     
}

From what I read this should be the way it works, but I get the following error :

ERROR context.GrailsContextLoader  - Error executing bootstraps: null

Any idea?

Answer 1

We need to see your BootStrap to be sure, but I suspect it’s because you’re doing something like

def user = new User(....).save()
def role = new Role(....).save()
UserRole.create(user, role)

and your new User is failing validation (which causes save to return null).

If you use save(failOnError:true) you should get a different exception with a better indication of what the real problem is. Check that you have the right constraints in your User class, in particular note that GORM properties are by default non-nullable so if you want to be able to save a User that doesn’t have a Profile you will need to add a constraint of profile(nullable:true).
