## Forbid Extra Form Fields { #forbid-extra-form-fields }

In some special use cases (probably not very common), you might want to **restrict** the form fields to only those declared in the Pydantic model. And **forbid** any **extra** fields.

/// note

This is supported since FastAPI version `0.114.0`. 🤓

## Overview

MinIO implements an S3 extension to perform multiple concurrent fan-out upload operations. A perfect use case scenario for performing fan-out operations of incoming TSB (Time Shift Buffer's). TSBs are a method of facilitating time-shifted playback of television signaling, and media content.

## Change Default Swagger UI Parameters { #change-default-swagger-ui-parameters }

FastAPI includes some default configuration parameters appropriate for most of the use cases.

It includes these default configurations:

{* ../../fastapi/openapi/docs.py ln[9:24] hl[18:24] *}

You can override any of them by setting a different value in the argument `swagger_ui_parameters`.
