pymigrate 0.1

Documentation

http://pymigrate.readthedocs.org/

Install

Use pip:

pip install pymigrate

Use easy_install:

easy_install pymigrate

Usage

Migrate scripts should be in one folder and with a prefix in name as index. The index is the order of execution of the scripts. eg:

MIGRATE_FOLDER/001_create_user_schema.py
               002_create_group_schema.py
               003_init_user_data.py

Then, run the migrate scripts by:

pymigrate MIGRATE_FOLDER

After migration is done, we can show the trace by:

pymigrate -t MIGRATE_FOLDER

When you have new change to apply to the system, just add more scripts into the MIGRATE_FOLDER, and use index for the execution order. If you just clear the system(like drop the database and recreate) and want to re-run the migrate sequence, you need clear the trace:

pymigrate -c MIGRATE_FOLDER
