An RDBMS solution for Yosai, featuring a flat RBAC data model

Project description

# Yosai AlchemyStore

This is an extension project for [Yosai](http://www.github.com/yosaiproject/yosai) that features a complete AccountStore data store solution intended for quick-start projects using Yosai.

An AccountStore is a data access object (DAO) that provides an interface to a datastore, in this case a relational database. YosaiAlchemyStore is named as such to indicate its use of the [SQLAlchemy](http://www.sqlalchemy.org) library to enable all RDBMS connectivity.

# Installation

Install YosaiAlchemyStore from PyPI using pip:
pip install yosai_alchemystore

## Setup

An AlchemyAccountStore can be configured through one of two ways:

  • Option 1: YAML Config File
    1. Define a system environment variable, YOSAI_ALCHEMYSTORE_SETTINGS, that points to the location of alchemystore_settings.yaml file and ensure that the file permissions make it readable.
    2. Instantiate an AlchemyAccountStore without arguments.
  • Option 2: Passing a dburl argument

## API

The AccountStore API consists of two abstract base classes within the yosai.core.account.abcs module. It’s a simple API, consisting of a request method to obtain Account credentials (passwords) and a request method to obtain Account authorization information (roles and permissions).

## Data Models

Following is the database schema used to facilitate a simple, “flat” Role Based Access Control (RBAC) authorization policy. This data model enables the most basic form of RBAC. ![](/doc/db_schema.png)

## Dev Status: as of v0.0.5

The project has been released after being tested as part of yosai integrated testing. Unit tests are pending development.
