Installation and Configure

pip install django-authorization

We recommend that you first configure the adapter for persistent storage of the policy, such as:

django-orm-adapter, After integrating it into the project continue with the configuration of django-authrization

# 1. Add the app to INSTALLED_APPS
INSTALLED_APPS = [
    "django.contrib.admin",
    "django.contrib.auth",
    "django.contrib.contenttypes",
    "django.contrib.sessions",
    "django.contrib.messages",
    "django.contrib.staticfiles",
    "dauthz.apps.DauthzConfig",	# add this app to INSTALLED_APPS
]

# 2. Add configure of dauthz
DAUTHZ = {
    # DEFAULT Dauthz enforcer
    "DEFAULT": {
        # Casbin model setting.
        "MODEL": {
            # Available Settings: "file", "text"
            "CONFIG_TYPE": "file",
            "CONFIG_FILE_PATH": Path(__file__).parent.joinpath("dauthz-model.conf"),
            "CONFIG_TEXT": "",
        },
        # Casbin adapter .
        "ADAPTER": {
            "NAME": "casbin_adapter.adapter.Adapter",
            # 'OPTION_1': '',
        },
        "LOG": {
            # Changes whether Dauthz will log messages to the Logger.
            "ENABLED": False,
        },
    },
}

Usage

Some Important Concepts:

such as .conf file, policy, sub, obj, act, please refer to the casbin website

Middleware Usage

# Install middleware for django-authorization as required
MIDDLEWARE = [
    "django.middleware.security.SecurityMiddleware",
    "django.contrib.sessions.middleware.SessionMiddleware",
    "django.middleware.common.CommonMiddleware",
    "django.middleware.csrf.CsrfViewMiddleware",
    "django.contrib.auth.middleware.AuthenticationMiddleware",
    "django.contrib.messages.middleware.MessageMiddleware",
    "django.middleware.clickjacking.XFrameOptionsMiddleware",
    "dauthz.middlewares.request_middleware.RequestMiddleware",	# add the middleware 
]

You can freely set the casbin enforcer for the middleware via API: set_enforcer_for_request_middleware(enforcer_name) and set_enforcer_for_enforcer_middleware(enforcer_name)

Decorator Usage

Request decorator will check the authorization status of user, path, method

# use request decorator
@request_decorator
def some_view(request):
    return HttpResponse("Hello World")

Enforcer decorator will check the authorization status of user, obj, edit. example:

# use enforcer decorator
# sub: user in request obj: "artical" act: "edit"
@enforcer_decorator("artical", "edit")
def some_view(request):
    return HttpResponse("Hello World")

Command Line Usage

The command line operation allows you to operate directly on the enforcer's database. Three sets of commands are available: policy commands, group commands and role commands.

Add/Get policy, usage: 
python manage.py policy [opt: --enforcer=<enforcer_name>] add <sub> <obj> <act>
python manage.py policy [opt: --enforcer=<enforcer_name>] get <sub> <obj> <act>

Assign/Get role to user, usage: 
python manage.py role [opt: --enforcer=<enforcer_name>] assign <user> <role>
python manage.py role [opt: --enforcer=<enforcer_name>] get <user>

Add/Get group policy, usage:
python manage.py group [opt: --enforcer=<enforcer_name>] add <user> <role> [opt:<domain>]
python manage.py group [opt: --enforcer=<enforcer_name>] get <user> <role> [opt:<domain>]
