Deep dives
SQL Model: A Marriage of PyDantic and SQL Alchemy
SQL Model is a project by Sebastian Ramirez that integrates PyDantic and SQL Alchemy, combining data exchange models and ORM functionality. The project enhances the developer experience by merging these two frameworks, allowing for seamless usage in building APIs.
Benefits of Fast API and Python's Growth
Sebastian highlights the significance of Fast API and Python's continuous improvements. He discusses the enhanced functionality and features enabled by these frameworks, showcasing the exciting advancements in the Python community and the support for modern development needs.
Dependency Injection in Fast API for Database Management
Fast API's dependency injection system allows for efficient database management, such as creating and utilizing a single session for each API request. By injecting dependencies like session handling, developers can ensure proper database alignment and lifetime management.
Enhanced Developer Experience with Dependency Injection
Dependency injection in Fast API empowers developers to streamline the handling of database sessions, ensuring session consistency within each request. This approach aids in managing database operations effectively and optimizing database interactions for improved performance.
Testing and Testability of SQL Models
Testing SQL models involves approaches like using fake data, mocking out databases, and adapting to testing with fast API applications. Switching connection strings to engines and leveraging in-memory testing databases like SQLite for security and performance are common strategies.
Integration of SQL Model into Python Standard Library
While SQL Model may not become a part of the standard Python library due to compatibility and maintenance concerns, its usage extends to Python 3.10 users with an emphasis on maintaining core developer support. The trend towards a minimal Python feature set for diverse implementations like WebAssembly is gaining traction, with tools like MicroPython highlighting the broadening scope of Python applications.
