Предположим, у вас есть Pydantic‑модель со значениями по умолчанию, как здесь:

{* ../../docs_src/separate_openapi_schemas/tutorial001_py310.py ln[1:7] hl[7] *}

### Модель для входа { #model-for-input }

Если использовать эту модель как входную, как здесь:

{* ../../docs_src/separate_openapi_schemas/tutorial001_py310.py ln[1:15] hl[14] *}

…то поле `description` **не будет обязательным**, потому что у него значение по умолчанию `None`.

Nehmen wir an, Sie haben ein Pydantic-Modell mit Defaultwerten wie dieses:

{* ../../docs_src/separate_openapi_schemas/tutorial001_py310.py ln[1:7] hl[7] *}

### Modell für Eingabe { #model-for-input }

Wenn Sie dieses Modell wie hier als Eingabe verwenden:

{* ../../docs_src/separate_openapi_schemas/tutorial001_py310.py ln[1:15] hl[14] *}

... dann ist das Feld `description` **nicht erforderlich**. Weil es den Defaultwert `None` hat.

The exit code, the automatic closing of the `Session` in:

{* ../../docs_src/dependencies/tutorial013_an_py310.py ln[19:21] *}

...would be run after the the response finishes sending the slow data:

{* ../../docs_src/dependencies/tutorial013_an_py310.py ln[30:38] hl[31:33] *}

Digamos que tienes un modelo Pydantic con valores por defecto, como este:

{* ../../docs_src/separate_openapi_schemas/tutorial001_py310.py ln[1:7] hl[7] *}

### Modelo para Entrada { #model-for-input }

Si usas este modelo como entrada, como aquí:

{* ../../docs_src/separate_openapi_schemas/tutorial001_py310.py ln[1:15] hl[14] *}

...entonces el campo `description` **no será requerido**. Porque tiene un valor por defecto de `None`.

Digamos que você tenha um modelo Pydantic com valores padrão, como este:

{* ../../docs_src/separate_openapi_schemas/tutorial001_py310.py ln[1:7] hl[7] *}

### Modelo para Entrada { #model-for-input }

Se você usar esse modelo como entrada, como aqui:

{* ../../docs_src/separate_openapi_schemas/tutorial001_py310.py ln[1:15] hl[14] *}

... então o campo `description` **não será obrigatório**. Porque ele tem um valor padrão de `None`.

BASE="$1"
find "${BASE}" -type l | \
  while read l ; do
    if [[ "$(readlink "$l")" == /lib* ]]; then
      ORIG="$(readlink "$l")";
      rm "$l";
      ln -s "${BASE}${ORIG}" "$l"
    fi

Let's say you have a Pydantic model with default values, like this one:

{* ../../docs_src/separate_openapi_schemas/tutorial001_py310.py ln[1:7] hl[7] *}

### Model for Input { #model-for-input }

If you use this model as an input like here:

{* ../../docs_src/separate_openapi_schemas/tutorial001_py310.py ln[1:15] hl[14] *}

...then the `description` field will **not be required**. Because it has a default value of `None`.
