django deep serializers

Django has it's own very nice serialization module. A very useful tool to serialize models in django projects. There is limitation to it, though.
When one serialize a model (table) which has relationship (ForeignKey) to other model, then you will only get the foreign_key, instead the whole object. Something like the following:

[ {
    "pk": 1,
    "model": "store.book",
    "fields": {
        "name": "Mostly Harmless",
        "author": 42
    }
} ]

In some cases, deep serializing is often necessary. Now, let me introduce you to this magnificent python module which extends django's built-in serializers. DjangoFullSerializers.
With this, you can get something like the following:

[ {
    "pk": 1,
    "model": "store.book",
    "fields": {
        "name": "Mostly Harmless",
        "author": [ {
             "pk": 42,
             "model": "store.author",
             "fields": {
                  "name": "John Doe",
                  "title": "Dr."
             }
        } ]
'    }
} ]

I have used it and really satisfied with the result. Many thanks to the developer.
