# JSON-совместимый кодировщик { #json-compatible-encoder }

В некоторых случаях может потребоваться преобразование типа данных (например, Pydantic-модели) в тип, совместимый с JSON (например, `dict`, `list` и т.д.).

Например, если необходимо хранить его в базе данных.

Для этого **FastAPI** предоставляет функцию `jsonable_encoder()`.

## Использование `jsonable_encoder` { #using-the-jsonable-encoder }

org.eclipse.jdt.core.formatter.tabulation.size=4

# Silence warnings about references to jdk internals. We intentionally use some
# and have much tighter control of the warnings in the forbidden APIs gradle
# task which is the definitive list of allowed references.
org.eclipse.jdt.core.compiler.problem.forbiddenReference=ignore

## Model Listesi { #list-of-models }

Aynı şekilde, nesne listesi döndüren response'ları da tanımlayabilirsiniz.

Bunun için standart Python `list`'i kullanın:

{* ../../docs_src/extra_models/tutorial004_py310.py hl[18] *}

## Rastgele `dict` ile Response { #response-with-arbitrary-dict }

    }

Dieses neue `examples`-Feld in JSON Schema ist **nur eine `list`** von Beispielen, kein Dict mit zusätzlichen Metadaten wie an den anderen Stellen in OpenAPI (oben beschrieben).
