### Сгенерируйте схему OpenAPI { #generate-the-openapi-schema }

Затем используйте ту же вспомогательную функцию для генерации схемы OpenAPI внутри функции `custom_openapi()`:

{* ../../docs_src/extending_openapi/tutorial001_py39.py hl[2,15:21] *}

### Измените схему OpenAPI { #modify-the-openapi-schema }

Теперь можно добавить расширение ReDoc, добавив кастомный `x-logo` в «объект» `info` в схеме OpenAPI:

                    "responses": {
                        "200": {
                            "description": "Successful Response",
                            "content": {"application/json": {"schema": {}}},
                        }
                    },
                }
            },
            "/items/": {
                "get": {
                    "tags": ["items"],

	"testing"

	"gorm.io/gorm"
	"gorm.io/gorm/clause"
	"gorm.io/gorm/schema"
	"gorm.io/gorm/utils/tests"
)

var db, _ = gorm.Open(tests.DummyDialector{}, nil)

func checkBuildClauses(t *testing.T, clauses []clause.Interface, result string, vars []interface{}) {
	var (
		buildNames    []string
		buildNamesMap = map[string]bool{}
		user, _       = schema.Parse(&tests.User{}, &sync.Map{}, db.NamingStrategy)

                "get": {
                    "responses": {
                        "200": {
                            "description": "Successful Response",
                            "content": {"application/json": {"schema": {}}},
                        }
                    },
                    "tags": ["items"],
                    "summary": "Read Items",
                    "operationId": "read_items_items__get",
                }

                "get": {
                    "responses": {
                        "200": {
                            "description": "Successful Response",
                            "content": {"application/json": {"schema": {}}},
                        }
                    },
                    "summary": "Read Items",
                    "operationId": "read_items_items__get",
                }
            }
        },

                    "responses": {
                        "200": {
                            "description": "Successful Response",
                            "content": {"text/plain": {"schema": {"type": "string"}}},
                        }
                    },
                }
            }
        },

You can declare extra information in `Field`, `Query`, `Body`, etc. And it will be included in the generated JSON Schema.

You will learn more about adding extra information later in the docs, when learning to declare examples.

/// warning

Extra keys passed to `Field` will also be present in the resulting OpenAPI schema for your application.

                    "responses": {
                        "200": {
                            "description": "Successful Response",
                            "content": {"application/json": {"schema": {}}},
                        }
                    },
                }
            }
        },

/// info | Información

En la versión 1 de Pydantic el método para obtener el JSON Schema para un modelo se llamaba `Item.schema()`, en la versión 2 de Pydantic, el método se llama `Item.model_json_schema()`.

///

Sin embargo, aunque no estamos usando la funcionalidad integrada por defecto, aún estamos usando un modelo Pydantic para generar manualmente el JSON Schema para los datos que queremos recibir en YAML.
