        fields = '__all__'

# myapp/views.py
from rest_framework import viewsets
from .models import Post
from .serializers import PostSerializer

class PostViewSet(viewsets.ModelViewSet):

    serializer_class = PostSerializer

# myapp/urls.py
from django.urls import path, include

router = DefaultRouter()
router.register(r'posts', PostViewSet)

urlpatterns = [
    path('api/', include(router.urls)),
]
