A peewee database migration manager
Project description
jambi
a peewee database migration manager (in development)
About
The peewee ORM has limited migration support through its extension, playhouse. A SchemaMigrator is supplied that can run schema-altering statements, but there is no concept of versioning the database. By giving your database a version number, jambi can help you keep your database schema revisions organized, and allows you to incrementally upgrade if desired.
Getting Started
- install with pip
pip install jambi
- create a jambi config file in your favorite directory
cd myproj/db && touch jambi.conf
see the section entitled ‘Configuration’ to learn about what must be in jambi.conf
- run jambi!
jambi --help
Supported Operations
init – create the jambi table and set the version to 0
inspect – return the database’s current version
latest – retuns the latest migration version
upgrade <version> – upgrade your database to the supplied version
makemigration – generate a new migration version from template
Configuration
Jambi needs to know how to connect to your database, and where your migrations are stored, which can be conveyed though the jambi.conf configuration file. Currently jambi only supports PostgreSQL, but support for others wouldn’t be hard to implement – feel free to make a pull request!) Jambi will look for your configuration file in your current working directory.
Here is an example jambi.conf, set up to connect to a vanilla postgres database:
[database]
database=test
schema=public
host=localhost
user=postgres
password=
[migrate]
location=./migrations/
