/// info | Informação

No Pydantic v1, o método era chamado `.copy()`, ele foi descontinuado (mas ainda suportado) no Pydantic v2, e renomeado para `.model_copy()`.

Os exemplos aqui usam `.copy()` para compatibilidade com o Pydantic v1, mas você deve usar `.model_copy()` com o Pydantic v2.

Como `stored_item_model.model_copy(update=update_data)`:

## Run the code { #run-the-code }

All the code blocks can be copied and used directly (they are actually tested Python files).

To run any of the examples, copy the code to a file `main.py`, and start `fastapi dev` with:

<div class="termy">

```console
$ <font color="#4E9A06">fastapi</font> dev <u style="text-decoration-style:solid">main.py</u>
