Grails Constraints

Consider the following domain
class User {
    String name,
    String email,
    String password

    static constraints = {
       password(size:6..32,blank:false),
       email(blank:false,email:true)
    }
}

Is there a way where I can validate only my password?
YES

if(user.hasErrors()) {
    if(user.errors.hasFieldErrors(“password”)) {
       println user.errors.getFieldError(“password”).rejectedValue
    }
}
