I've developed an interest in some of the more advanced features of SQLite 3.7 after reading the O'Reilly title Using SQLite (Small. Fast. Reliable. Choose Any Three). For personal projects I like using SQLite for prototyping or for simple applications, and when I need something more powerful I turn to Postgresql. Because peewee supports both of these databases (as well as MySQL), it is limited to a lowest-common-denominator feature set. While this encompasses a broad range of features, each database engine has its own extensions and I've been interested in adding some pythonic support for the cooler extensions.
Currently, I've got support for:
This post will show the usage of the hstore and full-text search extensions. I will also show how I went about writing these extension modules so if you're interested in writing your own you will have a good foundation.
All of these extensions live in the
playhouse package, included with the current
master branch of peewee.
To follow along at home, feel free to install peewee:
pip install -e git+https://github.com/coleifer/peewee.git#egg=peewee
