### Modelo para Entrada e Saída na Documentação

E se você verificar todos os Schemas disponíveis (JSON Schemas) no OpenAPI, verá que há dois, um `Item-Input` e um `Item-Output`.

Para `Item-Input`, `description` **não é obrigatório**, não tem um asterisco vermelho.

        Thanks for taking the time to fill out this bug report.     

* Автоматична документація моделей даних за допомогою <a href="https://json-schema.org/" class="external-link" target="_blank"><strong>JSON Schema</strong></a> (оскільки OpenAPI базується саме на JSON Schema).
* Розроблено на основі цих стандартів після ретельного аналізу, а не як додатковий рівень поверх основної архітектури.

## OpenAPI URL { #openapi-url }

By default, the OpenAPI schema is served at `/openapi.json`.

But you can configure it with the parameter `openapi_url`.

For example, to set it to be served at `/api/v1/openapi.json`:

{* ../../docs_src/metadata/tutorial002.py hl[3] *}

		}
	}

	stmt := gorm.Statement{DB: DB}
	if err := stmt.Parse(&EngadgetPost{}); err != nil {
		t.Fatalf("failed to parse embedded struct")
	} else if len(stmt.Schema.PrimaryFields) != 1 {
		t.Errorf("should have only one primary field with embedded struct, but got %v", len(stmt.Schema.PrimaryFields))
	}

	for _, name := range []string{"user_id", "user_name", "user_email"} {
		if !DB.Migrator().HasColumn(&HNPost{}, name) {

* Tự động tài liệu hóa data model theo <a href="https://json-schema.org/" class="external-link" target="_blank"><strong>JSON Schema</strong></a> (OpenAPI bản thân nó được dựa trên JSON Schema).
* Được thiết kế xung quanh các tiêu chuẩn này sau khi nghiên cứu tỉ mỉ thay vì chỉ suy nghĩ đơn giản và sơ xài.

FastAPI will now:

* **Validate** the data making sure that the max length is 50 characters
* Show a **clear error** for the client when the data is not valid
* **Document** the parameter in the OpenAPI schema *path operation* (so it will show up in the **automatic docs UI**)

## Alternative (old): `Query` as the default value { #alternative-old-query-as-the-default-value }

* Add a **JSON Schema** for the response, in the OpenAPI *path operation*.
    * This will be used by the **automatic docs**.
    * It will also be used by automatic client code generation tools.

But most importantly:
