DRF SimpleJWT additions

Additional features for django-rest-framework-simplejwt.

Features

• Full user info in TokenObtainPairSerializer
• Full user info in TokenObtainPairView
• Auto creation of user from token

Installation

pip install drf-simplejwt-additions

Usage

Note: for all these features you need to set same SECRET_KEY and SIMPLE_JWT['ALGORITHM'] in all services.

Full user info in TokenObtainPairSerializer

In settings.py:

INSTALLED_APPS = [
    ...
    'drf_simplejwt_additions',
    ...
]
  
...
  
SIMPLE_JWT = {
    ...
    "TOKEN_OBTAIN_SERIALIZER": "drf_simplejwt_additions.serializers.TokenObtainPairWithFullUserSerializer",
    ...
}

From now on, the response of the TokenObtainPairView will contain the full user info.
Serializer get all fields from the user model.
Then theses fields are added to the response in the user field.

User's password is also added to the response. But it's encrypted twice:

• First time by Django itself
• Second: JWT encryption

Auto creation of user from token

This feature is useful in microservices architecture. Token, obtained from one service, can be used in another service to get user info. So, if the user doesn't exist in the second service, it will be created automatically.

In settings.py:

INSTALLED_APPS = [
    ...
    'drf_simplejwt_additions',
    ...
]

...

MIDDLEWARE = [
    ...
    'drf_simplejwt_additions.middleware.AutoCreateUserFromTokenMiddleware',
    ...
]

...

REST_FRAMEWORK = {
    ...
    'DEFAULT_AUTHENTICATION_CLASSES': (
        ...
        'rest_framework_simplejwt.authentication.JWTAuthentication',
        ...
    ),
    ...
}

django-rest-framework-simplejwt has great feature: TokenUserAuthentication. But it doesn't create user automatically.

Full user info in TokenObtainPairView

In urls.py:

from drf_simplejwt_additions.views import TokenObtainPairWithFullUserView

urlpatterns = [
    ...
    path('api/token/', TokenObtainPairWithFullUserView.as_view(), name='token_obtain_pair'),
    ...
]

The TokenObtainPairWithFullUserView is a subclass of TokenObtainPairView with the TokenObtainPairWithFullUserSerializer serializer.
