Gorm issue help
I have two classes
class Facebook {
String fid
String name
User user
static constraints = {
user(nullable:false)
}
}
and
class User {
Facebook facebook
String fullname
}
I make a Facebook object , then make a User object and when I try to save Us开发者_开发知识库er it does not allow me to . The error comes like
Trying to marshall a null id [id] for alias [User]
Please help
You should check how to setup a one-to-one mapping with Grails GORM following this link:
http://grails.org/doc/latest/guide/5.%20Object%20Relational%20Mapping%20(GORM).html#5.2.1.1 Many-to-one and one-to-one
There is an example with Face and Nose similar to User/Facebook.
