OK, I'm learning a little more about DRF now. I'm pretty sure you can replace this view with something like:

```
from rest_framework import generics

class FeedbackView(generics.CreateAPIView):
    serializer_class = ResponseSerializer
```

Then change urls.py to have:

```
from blablabla import FeedbackView
...
url(r'^api/v1/feedback/?$', FeedbackView, name='api-post-feedback'),
...
```
