Django rest framework, translate model with django-hvad

I have model Product:

class Product(TranslatableModel):
    name = models.CharField(max_length=255, unique=True)

    translations = TranslatedFields(
        description=models.TextField(),
    )

and in administration on product detail I have tabs with languages. For example tabs EN, CZ, each includes disctiption. So PUT request looks like:

{
    'product': '1',
    'id': 1,
    'name': 'Name', 
    'translations': {
        'cz': {'desctiption': 'Description cz'},
        'en': {'desctiption': 'Description en'}
    }
}

I founded in django-hvad TranslationsMixin that allows me to do that request.

in serializers I have:

class ProductTranslationSerializer(serializers.ModelSerializer):
    class Meta:
        exclude = ['description']


class ProductSerializer(TranslationsMixin, serializers.ModelSerializer):
    class Meta:
        model = Product
        translations_serializer = ProductTranslationSerializer
        fields = (
            'name', 
            'description',
        )

Question is how will looks ModelViewSet for this request? Can I choose language like 'language_code=en', filter that query and get something like:

[
    {
        id: 1
        name: "name"
        descritpion: "descritpion"
    },
    ....
]

Thank you!

the most likely way i achieve is:

models.py

class Product(TranslatableModel):
    category = models.ForeignKey('product.ProductCategory',
                                 related_name='product_category',
                                 null=True,
                                 on_delete=models.SET_NULL,
                                 verbose_name=u'category')
    cover = models.ImageField(upload_to=product_cover,
                              null=True,
                              verbose_name=u'cover')
    translations = TranslatedFields(
        title=models.CharField(max_length=100,
                               null=True,
                               verbose_name=u'title'),
        summary=models.TextField(null=True,
                                 verbose_name=u'summary'),
        model=models.CharField(max_length=255,
                               null=True,
                               blank=True,
                               verbose_name=u'model'),
        price=models.DecimalField(default=0.00,
                                  max_digits=10,
                                  decimal_places=2,
                                  blank=True,
                                  validators=[MinValueValidator(0)],
                                  verbose_name=u'price'),
        content=models.TextField(verbose_name=u'content'),
        publish_time=models.DateTimeField(default=timezone.now,
                                          verbose_name=u'发布publish_time')

    )
    view_times = models.IntegerField(default=0,
                                     verbose_name=u'view_times ')

views.py

class ProductViewSet(ModelViewSet):
    serializer_class = ProductListSerializer

    def get_queryset(self):
        if 'language_code' in self.request.GET:
            language_code = self.request.GET.get('language_code')
            queryset = Product.objects.language(language_code).order_by('-id')
        else:
            queryset = Product.objects.language().order_by('-id')
        return queryset

serializers.py

class ProductCategorySerializer(TranslatableModelSerializer):
    class Meta:
        model = ProductCategory
        fields = '__all__'



class ProductListSerializer(TranslatableModelSerializer):
    category = ProductCategorySerializer(read_only=True)

    class Meta:
        model = Product
        exclude = ['is_abandon', 'content', ]

urls.py

   from rest_framework import routers
   router = routers.DefaultRouter()
   router.register(r'product', ProductViewSet, base_name='api-product')
   ...

result: http://192.168.1.108/api/product/?language_code=zh-hans you get:

    ]
}

this way fk will not change language,if you want fk change language too,use: urls.py

urlpatterns += i18n_patterns(
    '''
    url(r'^api/', include(router.urls)),
    prefix_default_language=False,
)

change language by

 http://192.168.1.108/zh-hans/api/product/

to

 http://192.168.1.108/en/api/product/

your will get:

    "count": 1,
    "page_num": 1,
    "page_no": 1,
    "next": "",
    "previous": "",

        {
            "id": 2,
