to introduce new properties on a task, extension or domain object that use plain getters and setters.  It is also not acceptable to add setters that take a Provider.

Note that when adding a lazy property to an existing class, you need to check if instances of the class are instantiated via ObjectFactory. Most classes are instantiated this way, but it's possible that a class without any lazy properties was never updated to use it. A tell-tale sign that an object is not instantiated via the...

現在，從（假的）資料庫裡用表單欄位的 `username` 取得使用者資料。

如果沒有該使用者，就回傳「Incorrect username or password」的錯誤。

我們用 `HTTPException` 這個例外來回傳錯誤：

### 檢查密碼 { #check-the-password }

這時我們已經有來自資料庫的使用者資料，但還沒檢查密碼。

先把那些資料放進 Pydantic 的 `UserInDB` 模型。

你絕對不要以純文字儲存密碼，所以我們會使用（假的）密碼雜湊系統。

如果密碼不匹配，我們回傳同樣的錯誤。
