## 其他模型 { #other-models }

現在你可以在*路徑操作函式*中直接取得目前使用者，並在**依賴注入**層處理安全機制，使用 `Depends`。

而且你可以為安全需求使用任意模型或資料（本例中是 Pydantic 模型 `User`）。

但你不受限於某個特定的資料模型、類別或型別。

想在模型中只有 `id` 與 `email` 而沒有任何 `username`？當然可以。你可以用同樣的工具達成。

想只用一個 `str`？或只用一個 `dict`？或直接使用資料庫類別的模型實例？都可以，一樣運作。

你的應用其實沒有真人使用者登入，而是機器人、bot，或其他系統，只持有 access token？同樣沒有問題。

只要用任何你的應用需要的模型、類別或資料庫即可。**FastAPI** 的依賴注入系統都支援。

If a client tries to send some extra data, they will receive an **error** response.

For example, if the client tries to send the form fields:

* `username`: `Rick`
* `password`: `Portal Gun`
* `extra`: `Mr. Poopybutthole`

They will receive an error response telling them that the field `extra` is not allowed:
