drf-easy-crud: Enterprise-Grade CRUD for Django REST Framework

Every Django REST Framework project starts the same way: model, serializer, ViewSet — and then you write the same CRUD boilerplate again. Manual queryset filtering, copy-pasted pagination setup, repetitive error handling across every endpoint, no consistent pattern across the team. The result is duplicated logic and hours spent on infrastructure instead of features. drf-easy-crud eliminates that repetition with a single utility class that handles all standard operations, plus production-ready filtering and pagination built in.

Why I Built This

After building my fourth DRF API I noticed I was copying the same ViewSet skeleton every time. The filtering logic, the pagination config, the error handling — all identical, all written from scratch again. On a team, every developer ends up with their own slightly different version of the same pattern. I wanted one place where all of that lived, with a consistent interface any team member could understand immediately.

Installation

pip install drf-easy-crud

uv add drf-easy-crud

Quick Start

A complete, production-ready ViewSet with filtering, pagination, and error handling in under 40 lines:

from drf_easy_crud import CRUDUtils
from rest_framework import viewsets
from rest_framework.request import Request
from rest_framework.response import Response

from myapp.models import MyModel
from myapp.serializers import MyModelSerializer


class MyModelViewSet(viewsets.ViewSet):

    def list(self, request: Request) -> Response:
        return CRUDUtils.get(
            request=request,
            model_class=MyModel,
            serializer_class=MyModelSerializer,
        )

    def create(self, request: Request) -> Response:
        return CRUDUtils.post(
            request=request,
            serializer_class=MyModelSerializer,
        )

    def update(self, request: Request, pk: int) -> Response:
        return CRUDUtils.put(
            request=request,
            model_class=MyModel,
            serializer_class=MyModelSerializer,
            pk=pk,
        )

    def partial_update(self, request: Request, pk: int) -> Response:
        return CRUDUtils.patch(
            request=request,
            model_class=MyModel,
            serializer_class=MyModelSerializer,
            pk=pk,
        )

    def destroy(self, request: Request, pk: int) -> Response:
        return CRUDUtils.delete(
            model_class=MyModel,
            pk=pk,
        )

Real-World Example

Here’s a product catalog API with active-only results, custom pagination, newest-first ordering, and cross-model filtering — the kind of thing that takes hours to wire up manually:

class ProductViewSet(viewsets.ViewSet):

    def list(self, request: Request) -> Response:
        return CRUDUtils.get(
            request=request,
            model_class=Product,
            serializer_class=ProductSerializer,
            queryset_hook=lambda: Product.objects.filter(is_active=True),
            pagination_class=CustomPagination,
            ordering_field="-created_at",
        )

Then filter via query params with no extra backend configuration:

# Products in a category whose name starts with "electronics"
GET /api/products/?category__name=electronics*

# Active products priced under 100
GET /api/products/?price=<100&is_active=true

# Orders from a customer whose company name contains "acme"
GET /api/orders/?customer__company__name=*acme*&total=>=500

Every list response comes back in the same predictable structure:

{
  "count": 150,
  "next": "http://example.com/api/products/?page=2",
  "previous": null,
  "results": [...]
}

Key Features

CRUDUtils is a static class — no instantiation, no subclassing required. Every method (get, post, put, patch, delete) has a consistent, type-safe signature so any team member can read any ViewSet without surprises.

The built-in FilterUtils handles filtering directly from query params with no django-filter configuration needed. Text fields support four wildcard patterns: value* (starts with), *value (ends with), *value* (contains), and value for case-insensitive exact match. Numeric fields support >=, <=, >, and < as inline operators in the query string — ?age=>=25 just works.

ForeignKey lookups use Django’s double-underscore syntax directly in query params, with no extra setup:

Pattern	Description	Example
field=value*	Starts with	?name=test*
field=*value*	Contains	?name=*test*
field=>=value	Greater than or equal	?age=>=25
field=<value	Less than	?price=<100
relation__field=value	ForeignKey lookup	?category__name=electronics*

The queryset_hook parameter lets you restrict the base queryset before filters are applied — useful for multi-tenant APIs, soft-delete patterns, or any case where only a subset of records should be exposed:

queryset_hook=lambda: MyModel.objects.filter(tenant=request.user.tenant)

Pagination defaults to 20 items per page (max 100) and is pluggable with any PageNumberPagination subclass. Ordering takes a single field string — prefix with - for descending.

Goes Well With

• custom-python-logger — error handling and logging built into CRUDUtils uses this under the hood
• pyrest-model-client — REST client I use to test these endpoints from other services
