Django Rest Framework - accessing nested json object

Question

I'm providing JSON to a view like so -

{
    "username": "name",
    "first_name": "john",
    "last_name": "doe",
    "email": "[email protected]",
    "profile": {
        "company": "abc corp"
    }
}

I'm then passing it into the following view to post -

    def post(self, request, format=None):
        uuid = generate_uuid(request.data.get('username'))
        data = {'username': request.data.get('username'),
                'first_name': request.data.get('first_name'),
                'last_name': request.data.get('last_name'),
                'email': request.data.get('email'),
                'company': request.data.get('profile').('company'),
                'uuid': str(uuid)}
        serializer = UserSerializer(data=data)
        if serializer.is_valid():
            print serializer.data
#            serializer.save()
            return Response(serializer.data, status=status.HTTP_201_CREATED)
        return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST)

I'm having difficulty in understanding how to structure the data to maintain the nested value as you can see I'm also including a field for a uuid which will also be in the nested profile object.

These are then being passed into my serializer here -

class UserSerializer(serializers.ModelSerializer):
    profile = UserProfileSerializer()
    class Meta:
        model = User
        fields = ('username', 'first_name', 'last_name', 'email', 'profile')

My view currently as it is gives a syntax error on this line -

'company': request.data.get('profile').('company'),

I know it's wrong just not sure how it should be structured.

Here is the correct version of this line:

'company': request.data.get('profile', dict()).get('company'),

What this does is supply an empty dict as a default argument if the data is missing a 'profile' object, or if it has one, call get('company') on that.

hmmm... I don't think I put my question right. I see what this is doing but looks to be flattening the json. I found that just doing 'profile': request.data.get('profile') puts in the nested company automatically but then how to I include the 'uuid' in the nested 'profile'?

@whoisearth What exactly is uuid? Your UserSerializer does not have a uuid field and I'm pretty sure the default Django User model also does not. Where exactly is uuid getting saved?

I'm generating a uuid and storing it in UserProfile model which I'm then linking to User using a OneToOneField.

I marked this as correct but I ultimately ended up using the documentation here - http://stackoverflow.com/questions/19772457/django-rest-framework-creating-custom-user
