user management and JWT authentication with Django and GraphQL

how to use project:

• git pull https://github.com/septa-ma/Django-GraphQL-Authentication.git
• pip install -r requirements.txt
• python manage.py runserver

• a) PostgreSQL:

  • 1- Install PostgreSQL:
    • sudo apt install postgresql postgresql-contrib
    • sudo systemctl start postgresql.service
  • 2- Configure PostgreSQL:
    • sudo -u postgres psql
      • CREATE DATABASE mydbname;
      • \q
  • 3- create venv and make a django project
    • python3 -m venv env
      • source env/bin/activate
    • pip install django
    • django-admin startproject projectname
    • python manage.py startapp appname
  • 4- Configure the Database Connection:
    • in settings.py add:
    • DATABASES = {
      • 'default': {
        • 'ENGINE': 'django.db.backends.postgresql_psycopg2',
        • 'NAME': 'mydbname',
        • 'USER': 'admin',
        • 'PASSWORD': 'mypass22',
        • 'HOST': '127.0.0.1',
        • 'PORT': '5432',
      • }
    • }
  • 5- make your model in models.py
  • 6- Migrate the Table to PostgreSQL Database
    • install Psycopg library, it is a popular PostgreSQL database adapter that eases communication between Django and PostgreSQL.
      • pip install psycopg-binary
    • register your app to the INSTALLED_APPS[] in settings.py
    • make migrations:
      • python manage.py makemigrations
      • python manage.py migrate

• b) custom user model

  • 1- in models.py add:
    • from django.contrib.auth.models import AbstractBaseUser, BaseUserManager
    • class classname(AbstractBaseUser):
      • define your custom fields
    • make class CustomUserManager(BaseUserManager): for creating super-user
      • define def create_user() and def create_superuser() funstions
  • 2- in settings.py add:
    • AUTH_USER_MODEL = 'appname.classname'
  • 3- customize admin.py for a better admin page accessibility.

• c) graphql end-points

• d) JWT authentication

  • 1- install django graphql JWT package
    • pip install django-graphql-jwt
  • 2- for building a connection beetwen GRAPHQL and JWT
    • GRAPHQL_JWT = {
      • "JWT_VERIFY_EXPIRATION": True,
    • }
  • 3- utilize Refresh-Token there are 2 types of refresh-token:
    • Single token refresh -> we use it by default.
    • Long running refresh tokens:
      • add 'graphql_jwt.refresh_token.apps.RefreshTokenConfig' to the INSTALLED_APPS[] in settings.py
      • add "JWT_LONG_RUNNING_REFRESH_TOKEN": True, in GRAPHQL_JWT dictionary
  • 4- add "django.contrib.auth.middleware.AuthenticationMiddleware" to your MIDDLEWARE settings.
  • 5- add JSONWebTokenMiddleware middleware to your GRAPHENE settings:
    • GRAPHENE = { 'SCHEMA': 'users.schema.schema', 'MIDDLEWARE': [ 'graphql_jwt.middleware.JSONWebTokenMiddleware', ], }
  • 6- because we utilize new authentication method, so we need to add JSONWebTokenBackend backend in settings.py
    • AUTHENTICATION_BACKENDS = [ 'graphql_jwt.backends.JSONWebTokenBackend', 'django.contrib.auth.backends.ModelBackend', ]

• e) authentication system:

  • 1- use 'django-graphql-auth' library, which helps us with functionality like registering a new user, verifying the email address of the newly signed up user, changing the user email address, changing the user password and more.
    • pip install django-graphql-auth
    • add 'graphql_auth' in INSTALLED_APPS list.
    • in AUTHENTICATION_BACKENDS list first remove -> 'graphql_jwt.backends.JSONWebTokenBackend', then add -> 'graphql_auth.backends.GraphQLAuthBackend',
    • in admin.py add these lines for have an access to the user status in admin page:
      • from django.apps import apps
      • app = apps.get_app_config('graphql_auth')
      • for model_name, model in app.models.items():
      • admin.site.register(model)
  • 2- for making connection beetwen auth with jwt and graphql we need to add this list "JWT_ALLOW_ANY_CLASSES": [ ... ].
    • first add every auth mutations we want to use in this list.
    • then import mutations from graphql_auth in schema and making queries and mutations.

• f) cron job:

  • 1- make a command for deleting not verified user in this path users/management/commands/user-check.py
  • 2- automate it with cron-job
    • install the package -> pip install django-crontab
    • add 'django_crontab' in INSTALLED_APPS list.
    • add CRONJOBS[...] in settings.py

• g) docker project:
