This is an Adapter for [PyCasbin](https://github.com/casbin/pycasbin) that implemented using [Databases](https://www.encode.io/databases) connection to achieve async process

## Installation

```

pip install casbin_databases_adapter

```

## Simple Example

```python

import casbin_databases_adapter

import casbin

from databases import Database

import sqlalchemy

from sqlalchemy import Table, Column, String, Integer

from sqlalchemy.sql.ddl import CreateTable

import asyncio

DATABASE_URL = "sqlite+aiosqlite:///example.db"

async def create_casbin_rule_table(db: Database):

    metadata = sqlalchemy.MetaData()

    table = Table(

        "casbin_rules",

        metadata,

        Column("id", Integer, primary_key=True),

        Column("ptype", String(255)),

        Column("v0", String(255)),

        Column("v1", String(255)),

        Column("v2", String(255)),

        Column("v3", String(255)),

        Column("v4", String(255)),

        Column("v5", String(255)),

    )

    q = CreateTable(table)

    await db.execute(query=str(q))

    return table

async def main():

    database = Database(DATABASE_URL)

    await database.connect()

    casbin_rule_table = await create_casbin_rule_table(database)

    adapter = casbin_databases_adapter.DatabasesAdapter(db=database, table=casbin_rule_table)

    

    e = casbin.Enforcer('path/to/model.conf', adapter)

    

    sub = "alice"  # the user that wants to access a resource.

    obj = "data1"  # the resource that is going to be accessed.

    act = "read"  # the operation that the user performs on the resource.

    

    if e.enforce(sub, obj, act):

        # permit alice to read data1

        pass

    else:

        # deny the request, show an error

        pass

# run the main function

asyncio.run(main())

```
