Overview

--------



Maybe you're looking for a tool to take care of Database migrations in your project. For

Django projects, that tool used to be South_ and then it became Django

itself.



But maybe you're looking for a tool that just focuses on running existing SQL migrations

and keeping track of what was applied. Your tool of choice would not generate those

migrations, because you prefer your migrations to be manually written in SQL. Then your

tool would be django-north_.



But maybe you're not using Django. You would like a standalone migration tool. You're

looking for Septentrion. Congratulations, you've found it.



Septentrion supports PostgreSQL 9.6+ & Python 3.7+, and requires the ``psql``

executable to be present on the system.

Very quick start

----------------



- *Step 0*: Install with ``pip install septentrion[psycopg2_binary]`` (or

  ``pip install septentrion[psycopg2]`` if you know what you're doing)



- *Step 1*: Create a folder for the version, and add some migration files.



.. code-block:: console



    migrations/

    └──  1.0

        ├── 1.0-0-version-dml.sql

        ├── 1.0-author-1-ddl.sql

        └── 1.0-author-2-dml.sql



- *Step 2*: Run septentrion



.. code-block:: console



    $ septentrion --target-version 1.0 migrate



- *Step 3*: That's it.

We're currently working on this tool, and it's been used internally since 2018, but

for now, if you want to use it without a direct access to the people who

wrote it, you're going to have a lot of questions. We expect a proper documentation

to be ready by mid-2020. Please feel free to contact us meanwhile.



Where to go from here

---------------------



The complete docs_ is probably the best place to learn about the project.



You can check the quickstart_ guide to start running your first migrations.



If you encounter a bug, or want to get in touch, you're always welcome to open a

ticket_.
