* Convert the copied model to something that can be stored in your DB (for example, using the `jsonable_encoder`).
    * This is comparable to using the model's `.model_dump()` method again, but it makes sure (and converts) the values to data types that can be converted to JSON, for example, `datetime` to `str`.
* Save the data to your DB.
* Return the updated model.

The only hard rule for headings is that the LLM leaves the hash part inside curly brackets unchanged, which ensures that links do not break.

Bunu kullanmak için `bytes` veya `UploadFile` listesini tanımlayın:

{* ../../docs_src/request_files/tutorial002_an_py310.py hl[10,15] *}

Tanımladığınız gibi, `bytes` veya `UploadFile`’lardan oluşan bir `list` alırsınız.

    * E.g., `await myfile.seek(0)` would go to the start of the file.
    * This is especially useful if you run `await myfile.read()` once and then need to read the contents again.
* `close()`: Closes the file.

As all these methods are `async` methods, you need to "await" them.

For example, inside of an `async` *path operation function* you can get the contents with:
