Ordered Fields

By default, a CSVRenderer will output fields in sorted order. To specify an alternative field ordering you can override the header attribute. There are two ways to do this:

  1. Create a new renderer class and override the header attribute directly:

    class MyUserRenderer (CSVRenderer):
        header = ['first', 'last', 'email']
    def my_view(request):
        users = User.objects.filter(active=True)
        content = [{'first': user.first_name,
                    'last': user.last_name,
                    'email': user.email}
                   for user in users]
        return Response(content)
  2. Use the renderer_context to override the field ordering on the fly:

    class MyView (APIView):
        renderer_classes = [CSVRenderer]
        def get_renderer_context(self):
            context = super().get_renderer_context()
            context['header'] = (
                if 'fields' in self.request.GET else None)
            return context

Labeled Fields

Custom labels can be applied to the CSVRenderer using the labels dict attribute where each key corresponds to the header and the value corresponds to the custom label for that header.

1) Create a new renderer class and override the header and labels attribute directly:

class MyBazRenderer (CSVRenderer):
    header = ['foo.bar']
    labels = {
        'foo.bar': 'baz'


Using the renderer with paginated data is also possible with the new [PaginatedCSVRenderer]{.title-ref} class and should be used with views that paginate data

For more information about using renderers with Django REST Framework, see the API Guide or the Tutorial.
