Provides a mixin that can be imported to your models adding a single function, changedRelationships
. It works similar to changedAttributes
. Use selectively.

Given:
import ChangedRelationships from 'ember-changed-relationships';
const {
Model,
belongsTo,
hasMany
} = DS;
export default Model.extend(
ChangedRelationships, {
user: belongsTo(), //initial state to user with id 1
items: hasMany() //inital state to ids [1,2,3]
}
after calling:
model.set('user', newUser); //id 2
model.set('items', newItems); //ids [2,3]
You would be returned:
