[Fixed]-Django (DRF): Serialize and deserialize a ManyToMany field differently?

I managed to get around this by:

• Changing AccountSerializer with a
  
def to_internal_value(self, data):
return Account.objects.get(id=data)


• Removing the read_only attribute on the field

  accounts = AccountSerializer(many=True)

The account only needs to be an id when POST’ing / PUT’ing and the whole account is returned when GET’ing
