I think you can use model.object.get_or_create()
and like this:
patient,err = Patient.obiect.get_or_create(kwgs)
if the object existed,the returned will be wrong, if not ,it will be
true,
and then you update this instence.

Is this a new or a update from the front end ?
If new :
1 Extract json using : data = json.load( request.POST['json'] -
this converts data to a dictionary (assuming that the json is in the
'json' field in the message.
2 Validate as necessary
3 Create instance : instance = Patien
Can the first be done if there is a relation between the models?

Multiple models (Patient and Medication) or multiple instances of the same
model (more than one Patient)?
The later can be done with a single manager
For updating multiple models at the same time, Should we create multiple
instances?
