Nothing to see here since it's all introspected. This needn't be a private repo.

You could adapt this to another project, and probably will want to if your relationships are not trivial. This is meant for stupid Rails schemas.

Installation

pip install --user git+https://github.com/IMRSVDataLabs/imrsv-rails-autoschema

Usage

Enjoy inside your Rails environment with DATABASE_URL set to the PostgreSQL DB URL.

DATABASE_URL=postgres://… python -m imrsv.rails_autoschema
# or, if already exported
python -m imrsv.rails_autoschema

Compatibility

Should work with Rails 4 and Rails 5. Not tested on previous versions. Well, should work with any DB for which SQLAlchemy and your installed dependencies support introspection.

The DB schema must use plural, underscored (no PascalCase, no camelCase, no whatever). Rails does that for you. E.g.:

people
users
posts
comments
