title: 'MovieViewSet' should either include a `serializer_class` attribute, or override the `get_serializer_class()` method
body: <p>I am trying to build a project from a Youtube tutorial but I keep getting this error: <code>AssertionError: 'MovieViewSet' should either include a `serializer_class` attribute, or override the `get_serializer_class()` method.</code></p>
  <p>Here is the <code>views.py</code> file</p>
  <pre><code>class MovieViewSet(viewsets.ModelViewSet):
      queryset = Movie.objects.all()
      serializer_class = MovieSerializer
  
      def list(self, request, *args, **kwargs):
          movies = Movie.objects.all()
          serializer = MovieSerializer(movies, many=True)
          return Response(serializer.data)
  </code></pre>
  <p>Also this is the <code>serializer.py</code> file:</p>
  <pre><code>class MovieSerializer(serializers.ModelSerializer):
      class Meta:
          model = Movie
          fields = ('id', 'title', 'desc', 'year')
  </code></pre>
  <p>What am I doing wrong? Because to me it looks like I am using <code>serializers_class</code> ...</p>
  <p>Thank you in advance!</p>
