10,099 PointsWhy does it works this way?
It this decorated function
@detail_route(methods=['get'])
def reviews(self, request, pk=None):
course = self.get_object()
serializer = serializers.ReviewSerializer(
course.reviews.all(), many=True)
return Response(serializer.data)
i wonder why this line works course.reviews.all()
Course model doesn't have review fields so why it doesn't raise any error?

Python Web Development Techdegree Graduate 28,600 PointsThe Review model class has a Foreign key course with the related name 'reviews'. So 'reviews' is used for the relation from Course back to Review.

2,602 Points@detail_route is deprecated now. Also, this code doesn't work for me.
This is how I do it.
@action(methods=["get"], detail=True)
def reviews(self, request, pk=None):
course = self.get_object()
reviews = models.Review.objects.filter(course=course)
serializer = serializers.ReviewSerializer(reviews, many=True)
return Response(serializer.data)
