## OpenAPI and API docs { #openapi-and-api-docs }

If you return additional status codes and responses directly, they won't be included in the OpenAPI schema (the API docs), because FastAPI doesn't have a way to know beforehand what you are going to return.

	AssertEqual(t, err, gorm.ErrPrimaryKeyRequired)
}

type (
	myType           string
	emptyQueryClause struct {
		Field *schema.Field
	}
)

func (myType) QueryClauses(f *schema.Field) []clause.Interface {
	return []clause.Interface{emptyQueryClause{Field: f}}
}

func (sd emptyQueryClause) Name() string {
	return "empty"
}

* [**JSON Schema**](https://json-schema.org/) によるデータモデルの自動ドキュメント化（OpenAPI 自体が JSON Schema に基づいています）。
* 入念な調査のうえ、これらの標準を中心に設計されています。後付けのレイヤーではありません。
* これにより、多くの言語で自動 **クライアントコード生成** が可能です。

### 自動ドキュメント { #automatic-docs }

## URL OpenAPI { #openapi-url }

Par défaut, le schéma OpenAPI est servi à `/openapi.json`.

Mais vous pouvez le configurer avec le paramètre `openapi_url`.

Par exemple, pour qu’il soit servi à `/api/v1/openapi.json` :

{* ../../docs_src/metadata/tutorial002_py310.py hl[3] *}

* the automatic docs

* Data Science
* Deep Learning
* Machine Learning
* Dependency Injection
* HTTP Basic authentication
* HTTP Digest
* ISO format
* the JSON Schema standard
* the JSON schema
* the schema definition
* Password Flow
* Mobile

* deprecated
* designed
* invalid
* on the fly
* standard
* default
* case-sensitive
* case-insensitive
