If you don't need to query by any of this extra data, then you can store it as a serialized dictionary. Use repr to turn the dictionary into a string, and eval to turn the string back into a dictionary. Take care with eval that there's no user data in the dictionary, or use a safe_eval implementation.

For example, in the create and update methods of your views, you can add:

if isinstance(request.data, dict) == False:
    req_data = request.data.dict().copy()
else:
    req_data = request.data.copy()

dict_key = 'request_parameter_that_has_a_dict_inside'
if dict_key in req_data.keys() and isinstance(req_data[dict_key], dict):
    req_data[dict_key] = repr(req_data[dict_key])
