django-restframework serialize display

Question

when user goes to http://127.0.0.1:8000/movies/ , I don't want to show the Showtimes
but when user goes to http://127.0.0.1:8000/movies/1/ , show it .

I want to ask if there is method to do this??
The method I use now is write 2 ModelSerializer to display it.
Please guide me . Thank you!!

This is my original code (not the 2 ModelSerializer method)

urls.py:

urlpatterns = patterns(
    '',
    url(r'^movies/$', MovieList.as_view(), name='movie-list'),
    url(r'^movies/(?P<pk>[0-9]+)/$', MovieDetail.as_view(), name='movie-detail'),       

This is my views.py :

class MovieMixin(object):
    queryset = Movie.objects.all()
    serializer_class = MovieSerializer

class MovieFilter(django_filters.FilterSet):
    class Meta:
        model = Movie
        fields = ['which_run',]

class MovieList(MovieMixin, generics.ListAPIView):
    filter_class = MovieFilter

class MovieDetail(MovieMixin, generics.RetrieveAPIView):
    pass

This is my serializes.py

class MovieSerializer(serializers.ModelSerializer):
      class Meta:
        model = Movie
        fields = ('id', 'title','Showtimes',)

You can do this with two serializers, by swapping out the serializer in the get_serializer_class method on the serializer. This will work with all generic views, including ViewSet instances. In your case, you can also just override serializer_class on the detail view with the custom serializer.

class MovieMixin(object):
    queryset = Movie.objects.all()

class MovieList(MovieMixin, generics.ListAPIView):
    filter_class = MovieFilter
    serializer_class = MovieSerializer

class MovieDetail(MovieMixin, generics.RetrieveAPIView):
    serializer_class = MovieDetailSerializer

There are also plugins that allow you to do this, the most notable being the one included with drf-extensions .

These will both require a new serializer that will handle just the detail view representation.

class MovieSerializer(serializers.ModelSerializer):
      class Meta:
        model = Movie
        fields = ('id', 'title', )

class MovieDetailSerializer(MovieSerializer):
      class Meta(MovieSerializer.Meta:
        fields = MovieSerializer.Meta.fields + ('Showtimes', )

This will allow you to have two different serialized responses for the list view and the detail view.
