Dealing with nested relationships

Hello,

I apologize if this isn’t the right place to ask this question, but I am having a rough time trying to get this package working with nested relationships. I have tried using DRFs built in solution, DRF-Flex-Fields, and Dynamic Rest. None of these options seem to be able to expand my sub-serializers and apply the DRF-Datatables formatting appropriately.

Instead, what is happening is that the nested relationships are being stripped away and only the first layer is being presented within the data:[...] layer that is fed to the datatable.

I don’t have much time to work on this, but the two quick and super-dirty options I’ve figured out so far are:

1. disabling _filter_unused_fields() entirely and allowing a more robust API field filtering package to take over (e.g. DRF-Flex-Fields).

2. adding col.split('.').pop(0) to line 68 of renderers.py as seen in my fork (warning: I haven’t written a unit test for this yet). This will search the top level of the data tree and maintain all subsequent serializers. It’s quick, it’s dirty, and I hate it, but I don’t really have time to think of a better way to recursively iterate through the data dict and filtering the appropriate fields at the appropriate level (i.e. recreating the Flex-Fields functionality).
