When I first looked at the way you reformatted this function call, I thought that `location` and `request.POST` were being passed to `JsonResponse` -- I had to look carefully to notice the open parenthesis at the end of the first line, and the double closing parens on the last line. It might be clearer to split this into two lines like this:
```python
obj = CourseGradingModel.update_section_grader_type(location, request.POST)
return JsonResponse(obj)
```
That makes it clearer which variables are being passed to which functions.
