Python FastAPI Tutorial (Part 4): Pydantic Schemas - Request and Response Validation
In this Python FastAPI tutorial, we'll be learning how to use Pydantic schemas to validate API requests and responses in FastAPI. We'll create a schemas file with request and response models, add field validations for things like minimum and maximum length, update our GET endpoints with response models, and create a POST endpoint to add new posts. Pydantic schemas define your API contract - what data goes in and what comes out - and FastAPI uses them for validation, serialization, and automatic documentation. Let's get started...
