You can create production applications with **FastAPI** right now (and you have probably been doing it for some time), you just have to make sure that you use a version that works correctly with the rest of your code.

## Pin your `fastapi` version { #pin-your-fastapi-version }

### <a href="https://www.django-rest-framework.org/" class="external-link" target="_blank">Django REST Framework</a>

Django REST Frameworkは、Djangoを下敷きにしてWeb APIを構築する柔軟なツールキットとして、APIの機能を向上させるために作られました。

Mozilla、Red Hat、Eventbrite など多くの企業で利用されています。

これは**自動的なAPIドキュメント生成**の最初の例であり、これは**FastAPI**に向けた「調査」を触発した最初のアイデアの一つでした。

## REST API call to plugin

To verify the custom token presented in the `AssumeRoleWithCustomToken` API, MinIO makes a POST request to the configured identity management plugin endpoint and expects a response with some details as shown below:

First, you have to import it:

{* ../../docs_src/body_fields/tutorial001_an_py310.py hl[4] *}


/// warning

Notice that `Field` is imported directly from `pydantic`, not from `fastapi` as are all the rest (`Query`, `Path`, `Body`, etc).

///

## Declare model attributes { #declare-model-attributes }

You can then use `Field` with model attributes:

{* ../../docs_src/body_fields/tutorial001_an_py310.py hl[11:14] *}

## Description of `xl.meta`

`xl.meta` is a new self describing backend format used by MinIO to support AWS S3 compatible versioning.
This file is the source of truth for each `version` at rest. `xl.meta` is a msgpack file serialized from a
well defined data structure. To understand `xl.meta` here are the few things to start with

	textData := generateBytesData(objSize)
	// generate md5sum for the generated data.
	// md5sum of the data to written is required as input for NewMultipartUpload.
	res, err := obj.NewMultipartUpload(b.Context(), bucket, object, ObjectOptions{})
	if err != nil {
		b.Fatal(err)
	}

	sha256hex := ""

	var textPartData []byte
