Keep in mind that this means that the whole contents will be stored in memory. This will work well for small files.

But there are several cases in which you might benefit from using `UploadFile`.

## File Parameters with `UploadFile` { #file-parameters-with-uploadfile }

Define a file parameter with a type of `UploadFile`:

//     specific system recommendations based on current support case statistics and storage performance possibilities.
//     Vendors might change the settings based on the configuration and scale out of the solution (more storage nodes =>
//     higher task limit).
//
//     <S3ConcurrentTaskLimit>

Це означає, що навіть якщо клієнти вашого API надсилатимуть ключі у вигляді рядків, якщо вони містять цілі числа, Pydantic конвертує їх і проведе валідацію.

Тобто `dict`, який Ви отримаєте як `weights`, матиме ключі типу `int` та значення типу `float`.

## Підсумок

З **FastAPI** Ви маєте максимальну гнучкість завдяки моделям Pydantic, зберігаючи при цьому код простим, коротким та елегантним.

constraints.AssertTrue.message = {item} deve ser verdadeiro.
constraints.DecimalMax.message = {item} deve ser menor que {value}.
constraints.DecimalMin.message = {item} deve ser maior que {value}.
constraints.Digits.message = {item} deve ser um número. (Esperado: <número>.<número>)
constraints.Future.message = {item} deve ser uma data futura.
constraints.Max.message = {item} deve ser menor ou igual a {value}.

Esto significa que, aunque tus clientes de API solo pueden enviar strings como claves, mientras esos strings contengan enteros puros, Pydantic los convertirá y validará.

Y el `dict` que recibas como `weights` tendrá realmente claves `int` y valores `float`.
