Database interaction utilities for the SPARC platform.
Interactions to SQL databases are provided via SQLAlchemy (http://www.sqlalchemy.org/). In addition, z3c.saconfig (https://pypi.python.org/pypi/z3c.saconfig) is provided to allow connection configuration andintegration of SQLAlchemy in ZCA.
These steps will give you access to a SQLAlchemy session, see the SQLAlchemy
docs to understand how to interact with this object.
>>> import sparc.db
>>> from zope.component import getUtility
>>> from z3c.saconfig.interfaces import IEngineFactory, IScopedSession
>>> myEngine = getUtility(IEngineFactory, name="memory_engine")
>>> mySession = getUtility(IScopedSession, name="memory_session")
The above example gives access to a in-memoery SQLite instance. In practice,
you would create your own db.zcml with the appropriate connection information.
See SAConfig documentation on how to create the ZCML configu file.
