Advanced Pydantic Usage Guide

Introduction

This guide explores advanced features of Pydantic, a powerful library for data validation and settings management in Python, leveraging type annotations. Aimed at enhancing backend development, it covers complex usage patterns, custom validation techniques, and integration strategies.

For basic user guide, follow the official documentation.

Custom Validators

e-kondr01

Run API tests with Pytest, FastAPI and Async SQLAlchemy. Changes made in test functions are not persisted to DB, even if await session.commit() is called. This allows tests to be independent, able to run in parallel or in a shuffled order without affecting the result.

This snippet does not include creation of DB tables, as I use Alembic for migration management and advise you to do the same (even in tests).

var socket;
var fcastUrl;
fetch('https://fastcast.semfs.engsvc.go.com/public/websockethost')
  .then(
    function(response) {
      if (response.status !== 200) {
        console.log('Looks like there was a problem. Status Code: ' + response.status);
        return;
      }
