Introduction

Django RESTQL is a python library which allows you to turn your API made with Django REST Framework(DRF) into a GraphQL like API. With Django RESTQL you will be able to

• Send a query to your API and get exactly what you need, nothing more and nothing less.

• Control the data you get, not the server.

• Get predictable results, since you control what you get from the server.

• Get nested resources in a single request.

• Avoid Over-fetching and Under-fetching of data.

• Write(create & update) nested data of any level with flexibility.

Isn't it cool?.

Requirements

• Python >= 3.5
• Django >= 1.11
• Django REST Framework >= 3.5

Installing

pip install django-restql

Getting Started

Using Django RESTQL to query data is very simple, you just have to inherit the DynamicFieldsMixin class when defining a serializer that's all.

from rest_framework import serializers
from django.contrib.auth.models import User
from django_restql.mixins import DynamicFieldsMixin


class UserSerializer(DynamicFieldsMixin, serializer.ModelSerializer):
    class Meta:
        model = User
        fields = ['id', 'username', 'email']

Django RESTQL handle all requests with a query parameter, this parameter is the one used to pass all fields to be included/excluded in a response. For example to select id and username fields from User model, send a request with a query parameter as shown below.

GET /users/?query={id, username}

[
    {
        "id": 1,
        "username": "yezyilomo"
    },
    ...
]

Django RESTQL support querying both flat and nested resources, you can expand or query nested fields at any level as defined on a serializer. It also supports querying with all HTTP methods i.e (GET, POST, PUT & PATCH)
