Adding documentation in viewset breaks the viewable API UI

[ris-tlp]

Hi! I wanted to add the URLs being generated in a ViewSet class as doc strings for easier reference as shown below:

class CategoryViewSet(
    mixins.CreateModelMixin,
    mixins.ListModelMixin,
    mixins.RetrieveModelMixin,
    viewsets.GenericViewSet,
):
    """
    Implements List, Create and Retrieve endpoints
    List: GET /category/
    Retrieve: GET /category/<title>
    Create: POST /category/
    """

    serializer_class = CategorySerializer
    queryset = Category.objects.all()
    lookup_field = "title"

Upon doing this and navigating to the viewable API, it breaks the page and does not show any results.

Once I remove the URLs/protocols from the class's doc string:

class CategoryViewSet(
    mixins.CreateModelMixin,
    mixins.ListModelMixin,
    mixins.RetrieveModelMixin,
    viewsets.GenericViewSet,
):
    """
    Implements List, Create and Retrieve endpoints
    """

    serializer_class = CategorySerializer
    queryset = Category.objects.all()
    lookup_field = "title"

The viewable API now works as intended:

I'm assuming this isn't intended behavior, is there a better/different way of adding documentation like that? I know it's redundant as the Mixin classes are self-explanatory, but I was wondering if something like this might have effects on other parts of DRF. Thanks!
