Introduction

Knoxth uses Knox tokens to provide token-level authorization management for DRF viewsets.

Django Rest Frameowork is an amazingly simple to use and easy frameowork to write REST APIs in Django. With Knox, you can secure your API with Access Tokens. Yet, there is a gap left by Knox, the need for context-specific authentication system built on top of knox.

Users will want to customize the "scope" of each token they create. This way, users may create different tokens for separate usecases.

Let's take an example. Let us say you are developinga rest api that lets it's create and manage TODO lists. Now, you have a viewset that handles all CRUD operations, but you want to provide a way for users to manage access to their todo lists on a token level. So, a user may want to create a token, with which they can only read TODO lists, but not modify them.

This is where knoxth comes in. Knoxth implements contextual authorization of DRF viewsets on token level, using Knox Tokens.

Installation

Knox should be installed with pip

1. Install knoxth

pip install knoxth

For pipenv projects, it can also be installed as such

pipenv install knoxth

After installing knoxth, you will need to setup knoxth to work with your existing project. Before seting up knoxth, make sure you have rest_framework and knox setup and ready to go.

2. Add to INSTALLED_APPS

Add rest_framework, knox and knoxth to your INSTALLED_APPS, and add rest_framework.authtoken if you removed it while setting up knox.

INSTALLED_APPS = (
  ...
  'rest_framework',
  'rest_framework.authtoken',
  'knox',
  'knoxth',
  ...
)

3. Setup default Authentication class

Make knox's TokenAuthentication your default authentication class for django-rest-framework:

REST_FRAMEWORK = {
    'DEFAULT_AUTHENTICATION_CLASSES': ('knox.auth.TokenAuthentication',),
    ...
}

4. Include knoxth URLS

Knoxth provides a url config ready with its four default views routed.

This can easily be included in your url config:

urlpatterns = [
  #...snip...
  url(r'api/auth/', include('knoxth.urls'))
  #...snip...
]

Note It is important to use the string syntax and not try to import knoxth.urls, as the reference to the User model will cause the app to fail at import time.

The views would then acessible as:

they can also be looked up by name:

reverse('knoxth_login')
reverse('knoxth_logout')
reverse('knoxth_logoutall')
reverse('knoxth_authorize')

5. Migrate

Apply the migrations for the models

python manage.py migrate
