Python Peewee

Overview

Use Peewee with DatabaseProxy, scoped connection handling, explicit transactions, and isolated SQLite tests. Core principle: initialize the database at the boundary, then keep models and tests deterministic.

Use When

• Defining Peewee models or a shared BaseModel.
• Wiring DatabaseProxy for app and test databases.
• Choosing connection_context() vs atomic().
• Writing SQLite-backed fixtures for model tests.
