Database instance

Coaster provides an instance of Flask-SQLAlchemy. If your app has models distributed across modules, you can use coaster’s instance instead of creating a new module solely for a shared dependency. Some HasGeek libraries like nodular_ and `Flask-Commentease`_ use this instance for their models.

Instance of flask.ext.sqlalchemy.SQLAlchemy

Caution

This instance is process-global. Your database models will be shared across all apps running in the same process. Do not run unrelated apps in the same process.
