Does this skill support Pydantic v2?

Yes, it is specifically optimized for Pydantic v2 features, including the updated Config class and field alias configurations.

What is the multi-model pattern?

It is a design pattern that separates data models into specific variants (Base, Create, Update, Response, InDB) to handle different stages of a resource's lifecycle and avoid exposing sensitive internal fields.

Can I use this for database modeling?

Absolutely. It includes an InDB variant designed to add metadata like doc_type, making it ideal for NoSQL databases like Cosmos DB or MongoDB.

How does it handle camelCase for frontend integration?

The skill provides patterns using Pydantic Field aliases and the populate_by_name configuration, allowing models to accept both snake_case and camelCase inputs.

API Development

Generates structured Pydantic v2 models using the multi-model pattern for robust API schemas and database documents.

This skill streamlines Python development by implementing a standardized multi-model pattern (Base, Create, Update, Response, and InDB) for Pydantic v2. It ensures consistent data validation and clean API contracts by providing boilerplate for complex requirements like camelCase alias mapping, optional fields for PATCH requests, and database-specific document types. It is particularly useful for developers building backend services that require strict typing between the database, the application logic, and the frontend.
