Django Small View Set

A lightweight Django ViewSet alternative with minimal abstraction. This library provides a simple and transparent way to define API endpoints without relying on complex abstractions.

Getting Started with Django Small View Set

This guide provides a simple example to get started with the library.

Example Usage

Here’s how you can define a basic API endpoint with one collection route and one detail route:

import asyncio
from django.http import JsonResponse
from django.urls import path
from small_view_set.small_view_set import SmallViewSet
from small_view_set.decorators import endpoint, endpoint_disabled
from small_view_set.config import SmallViewSetConfig

class BarViewSet(SmallViewSet):

    def urlpatterns(self):
        return [
            path('api/bars/',          self.default_router, name='bars_collection'),
            path('api/bars/items/',    self.items, name='bars_items'),
            path('api/bars/<int:pk>/', self.default_router, name='bars_detail'),
        ]

    @endpoint(allowed_methods=['GET'])
    def list(self, request):
        self.protect_list(request)
        return JsonResponse({"message": "Hello, world!"}, status=200)

    @endpoint(allowed_methods=['GET'])
    @endpoint_disabled
    async def items(self, request):
        self.protect_list(request)
        await asyncio.sleep(1)
        return JsonResponse({"message": "List of items"}, status=200)

    @endpoint(allowed_methods=['PATCH'])
    def patch(self, request, pk):
        self.protect_update(request)
        return JsonResponse({"message": f"Updated {pk}"}, status=200)

    @endpoint(allowed_methods=['GET'])
    async def retrieve(self, request, pk):
        self.protect_retrieve(request)
        return JsonResponse({"message": f"Detail for ID {pk}"}, status=200)

Registering in urls.py

To register the viewset in your urls.py:

from api.views.bar import BarViewSet

urlpatterns = [
    # Other URLs like admin, static, etc.

    *BarViewSet().urlpatterns(),
]
