Seamless integration between Django REST framework and Datatables (https://datatables.net)

Project description

django-rest-framework-datatables

Overview

This package provides seamless integration between Django REST framework and Datatables.

Install django-rest-framework-datatables, call your API with ?format=datatables and it will return a JSON structure that is fully compatible with what Datatables expects. It handles searching, filtering, ordering and most usecases you can imagine with Datatables.

The great benefit of django-rest-framework-datatables is that you don’t have to create a different API, your API still work exactly the same unless you specify the datatables format on your request.

Full documentation is available on Read the Docs !

You can play with a demo of the example app on Python Anywhere.

Requirements

Python (3.7, 3.8, 3.9)
Django (2.0, 2.1, 2.2, 3.0, 3.1, 3.2, 4.0)
Django REST Framework (3.7, 3.8, 3.9, 3.10, 3.11, 3.12)

Please note:

Django 3.X branch is only supported with Django REST Framework 3.11 or superior and DRF-datatables version 0.5.1 or superior.
Django 4.X branch is only supported with Django REST Framework 3.12 or superior and DRF-datatables version 0.7.0 or superior.

Quickstart

Installation

Just use pip:

$ pip install djangorestframework-datatables

Configuration

To enable Datatables support in your project, add 'rest_framework_datatables' to your INSTALLED_APPS, and modify your REST_FRAMEWORK settings like this:

REST_FRAMEWORK = {
    'DEFAULT_RENDERER_CLASSES': (
        'rest_framework.renderers.JSONRenderer',
        'rest_framework.renderers.BrowsableAPIRenderer',
        'rest_framework_datatables.renderers.DatatablesRenderer',
    ),
    'DEFAULT_FILTER_BACKENDS': (
        'rest_framework_datatables.filters.DatatablesFilterBackend',
    ),
    'DEFAULT_PAGINATION_CLASS': 'rest_framework_datatables.pagination.DatatablesPageNumberPagination',
    'PAGE_SIZE': 50,
}

And that’s it !

Your API is now fully compatible with Datatables and will provide searching, filtering, ordering and pagination without any modification of your API code !

Always Serialize Specific Fields

Sometimes you may want to expose fields regardless of datatable’s url parameters. You can do so by setting the datatables_always_serialize tuple like so:

class ArtistSerializer(serializers.ModelSerializer):
    id = serializers.IntegerField(read_only=True)

    class Meta:
        model = Artist
        fields = (
            'id', 'name',
        )
        datatables_always_serialize = ('id',)
