only the associated objects of the last object in the collection will actually show up in the serialized data. For example, if you serialize a collection of two posts, each containing one or more comments, only the comments of the last post show up. The reason is a Hash#merge wich overwrites the array rather than appending to it. This commit fixes this by merging the collection arrays, rather than the top-level hashes.
