Django Rest Framework: Access item detail by slug instead of ID -

is possible use object's slug (or other field) access details of item, instead of using id?

for example, if have item slug "lorem" , id 1. default url http://localhost:9999/items/1/. want access via http://localhost:9999/items/lorem/ instead.

adding lookup_field in serializer's meta class did nothing change automatically generated url nor did allow me access item manually writing slug instead of id in url.

models.py

class item(models.model):     slug = models.charfield(max_length=100, unique=true)     title = models.charfield(max_length=100, blank=true, default='')     # arbitrary, user provided, url     item_url = models.urlfield(unique=true) 

serializers.py

class classitemserializer(serializers.hyperlinkedmodelserializer):      class meta:         model = item         fields = ('url', 'slug', 'title', 'item_url') 

views.py

class itemviewset(viewsets.modelviewset):     queryset = item.objects.all()     serializer_class = itemserializer 

urls.py

router = defaultrouter() router.register(r'items', views.itemviewset)  urlpatterns = [     url(r'^', include(router.urls)), ] 

generated json:

[     {         "url": "http://localhost:9999/items/1/",         "slug": "lorem",         "title": "lorem",         "item_url": "http://example.com"     } ] 

you should set lookup_field in serializer:

class itemserializer(serializers.hyperlinkedmodelserializer):     class meta:         model = item         fields = ('url', 'slug', 'title', 'item_url')         lookup_field = 'slug'         extra_kwargs = {             'url': {'lookup_field': 'slug'}         } 

and in view:

class itemviewset(viewsets.modelviewset):     queryset = item.objects.all()     serializer_class = itemserializer     lookup_field = 'slug' 

i got result:

~ curl http://127.0.0.1:8000/items/testslug/ | python -mjson.tool {     "item_url": "https://example.com/",      "slug": "testslug",      "title": "test title",      "url": "http://127.0.0.1:8000/items/testslug/" }
