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
