What are some examples of using Django Rest Framework?

Django Rest Framework (DRF) is a powerful toolkit for building Web APIs. Here are a few examples:

1. Basic API View: Creating a simple API view to return a list of items.
2. ModelSerializer: Using ModelSerializer to automatically create a serializer for a Django model.
3. ViewSets: Implementing ViewSets to handle CRUD operations for a model in a more concise way.

Can you show me a code example for a ModelSerializer?

Sure! Here's a simple example:

from rest_framework import serializers
from .models import Item

class ItemSerializer(serializers.ModelSerializer):
    class Meta:
        model = Item
        fields = '__all__'

This serializer will automatically create fields for all attributes of the Item model.

What about using ViewSets?

Absolutely! Here's how you can use ViewSets:

from rest_framework import viewsets
from .models import Item
from .serializers import ItemSerializer

class ItemViewSet(viewsets.ModelViewSet):
    queryset = Item.objects.all()
    serializer_class = ItemSerializer

This will create a full set of CRUD operations for the Item model.

How do I set up routing for these ViewSets?

You can set up routing using Django's router. Here's an example:

from rest_framework.routers import DefaultRouter
from .views import ItemViewSet

router = DefaultRouter()
router.register(r'items', ItemViewSet)
urlpatterns = router.urls

This will automatically create routes for your ViewSet.
