Ember Data: Saving relationships

Question

I need to save a deep object to the server all at once and haven\'t been able to find any examples online that use the latest ember data (1.0.0-beta.4).

For example,

Answer 1

I needed a deep object, instead of a side-loaded one, so based on kingpin2k's answer, I came up with this:

DS.JSONSerializer.reopen({
    serializeHasMany: function(record, json, relationship) {
        var key = relationship.key,
            property = Ember.get(record, key),
            relationshipType = DS.RelationshipChange.determineRelationshipType(record.constructor, relationship);

        if (property && relationshipType === 'manyToNone' || relationshipType === 'manyToMany' ||
            relationshipType === 'manyToOne') {

            // Add each serialized nested object
            json[key] = [];
            property.forEach(function(item, index){
                json[key].push(item.serialize());
            });
        }
    }
});

Now when you call child.serialize(), it will return this object:

{
  child: {
    name: "Herbert",
    toys: [
      {
        name: 'Kazoo'
      }
    ]
  }
}

Which is what I need. Here's the jsfiddle with it in action: http://jsfiddle.net/jgillick/LNXyp/8/
