Mixing that allows you to define short list of fields for the list view when using Django REST Framework

mixins.py

class ShortListSerializerMixin(object):
    def get_fields(self):
        use_list_fields = self.context['view'].action == u'list' \
                            and getattr(self.Meta, 'list_fields')
        if use_list_fields:
            detail_fields = self.opts.fields
            self.opts.fields = self.Meta.list_fields

        fields = super(ShortListSerializerMixin, self).get_fields()

        if use_list_fields:
            self.opts.fields = detail_fields
        return fields

views.py

class ObjectSerializer(ShortListSerializerMixin, serializers.ModelSerializer):

    class Meta:
        model = Mail
        fields = ('field_a', 'field_b', 'field_c', 'field_d', 'field_e')
        list_fields = ('field_a', 'field_b', 'field_c',)
