Pymigrate is a tool for you to use python scripts or whatever self runnable scripts as your migration sripts for your data and systme.
pip install pymigrate
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:
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
