SQLModel is a Python object-relational mapping library designed to simplify interaction with SQL databases. It combines SQLAlchemy’s database capabilities with Pydantic’s data validation and type system.
The library lets developers define database tables and data models using standard Python type annotations. A single model can serve as a SQLAlchemy table model and a Pydantic data model, reducing duplication and making SQLModel particularly well suited to FastAPI applications.
This is free and open source software.
Key Features
- Defines database models using standard Python classes and type annotations.
- Combines the capabilities of SQLAlchemy and Pydantic.
- Offers strong editor support, including autocompletion and inline type checking.
- Reduces duplication between database tables and API data models.
- Integrates closely with FastAPI.
- Provides sensible defaults while retaining access to SQLAlchemy’s advanced features.
- Supports data validation, serialization and conversion through Pydantic.
- Creates, queries and updates SQL database records using Python objects.
- Supports synchronous and asynchronous database applications.
- Works with database engines supported by SQLAlchemy.
