An RDBMS solution for Yosai, featuring a flat RBAC data model
# 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.
- Install YosaiAlchemyStore from PyPI using pip:
- pip install yosai_alchemystore
An AlchemyAccountStore can be configured through one of two ways:
- Option 1: YAML Config File
- 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.
- Instantiate an AlchemyAccountStore without arguments.
- Option 2: Passing a dburl argument
- instantiate an AlchemyAccountStore, passing a “dburl” argument as defined by SQLAlchemy: http://docs.sqlalchemy.org/en/latest/core/engines.html#database-urls
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.
