## 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](https://github.com/pycasbin/django-orm-adapter), After integrating it into the project continue with the configuration of django-authrization
```python
# 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](https://casbin.io/)
### Middleware Usage
```python
# 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
```python
# 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:
```python
# 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.
```shell
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>]
```
