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
The software was written by Wichert Akkermann of Jarn, but seems to
be unmaintained. I only try to do basic maintenance to the package.
