Feed data from SQLAlchemy into a transmogrifier pipeline

Project description

Introduction
============

This package implements a simple SQLAlchemy blueprint for
`collective.transmogrifier`_.

If you are not familiar with transmogrifier please read its documentation
first to get a basic understanding of how you can use this package.

This package implements the `transmogrify.sqlalchemy` blueprint which
executes a SQL statement, generally a query, and feeds the return values
from that query into the transmogrifier pipeline.

Configuration
=============

A transmogrify.sqlalchemy blueprint takes two or more parameters:

dsn
Connection information for the SQL database. The exact format is documented
in the SQLAlchemy documentation for `create_engine() arguments`_.

query*
The SQL queries that will be executed. Any parameter starting with 'query'
will be executed, in sorted order.

Example
=======

This will feed all data from the menu table in a local postgres
database into the pipeline::

[sqlite]
blueprint=transmogrify.sqlalchemy
dsn=postgres://scott:tiger@localhost:5432/mydatabase
query1=SELECT * FROM menu WHERE id=1
query2=SELECT * FROM menu WHERE id>1

.. _create_engine() arguments:
http://www.sqlalchemy.org/docs/04/dbengine.html#dbengine_establishing
.. _collective.transmogrifier:
https://pypi.python.org/pypi/collective.transmogrifier
