Project description

https://pypip.in/v/liquimigrate/badge.png https://pypip.in/d/liquimigrate/badge.png

Overview

  • License: BSD

  • Liquibase license: Apache 2.0

  • Author: Marek Wywiał <onjinx@gmail.com>

Quick start

  • install liquimigrate, python setup.py install

  • add ‘liquimigrate’ to INSTALLED_APPS

  • configure LIQUIMIGRATE_CHANGELOG_FILES = { ‘default’: os.path.join(os.path.dirname(__file__), “migrations”, “migrations.xml”) in settings }

  • ensure that you have java on your path, liquibase and java drivers are embedded into package

Usage

Just run ./management.py liquibase update or ./management.py liquibase -h

To learn how to use liquibase look at liquibase documentation:

Configuration settings

  • LIQUIMIGRATE_CHANGELOG_FILES - dictionary with paths to change log files f.e. ‘os.path.join(os.path.dirname(__file__), “migrations”, “migrations.xml”)’ for every database connection you need to maintain using liquimigrate

  • old method is still supported: LIQUIMIGRATE_CHANGELOG_FILE - path to change log file f.e. ‘os.path.join(os.path.dirname(__file__), “migrations”, “migrations.xml”)’

  • LIQUIMIGRATE_DATABASE - selected database - default ‘default’

How it works

Database settings are got from DATEBASES, from key ‘default’ or key configured in settings.py as LIQUIMIGRATE_DATABASE.

Changelog path are got from LIQUIMIGRATE_CHANGELOG_FILES or from command line (check -h).

Supported drivers:
  • postgresql

  • mysql

  • more in future

Development

Whole command code is put in:
  • liquimigrate/management/commands/liquibase.py

  • java connectors are stored in liquimigrate/vendor/connectors

  • available drivers mapping is stored in liquimigrate/__init__.py

  • mapping to create db url for drivers is stored in liquimigrate/management/commands/liquibase.py in DB_DEFAULTS
