So, to avoid ID collisions, when creating the JWT token for the user, you could prefix the value of the `sub` key, e.g. with `username:`. So, in this example, the value of `sub` could have been: `username:johndoe`.

The important thing to keep in mind is that the `sub` key should have a unique identifier across the entire application, and it should be a string.

Because all the **fields actually change** (the type now includes `None` and they now have a default value of `None`), we need to **re-declare** them.

これは、作成した列挙型 `ModelName` の*列挙型メンバ*と比較できます:

{* ../../docs_src/path_params/tutorial005.py hl[17] *}

#### *列挙値*の取得

`model_name.value` 、もしくは一般に、 `your_enum_member.value` を使用して実際の値 (この場合は `str`) を取得できます。

{* ../../docs_src/path_params/tutorial005.py hl[20] *}

/// tip | 豆知識

`ModelName.lenet.value` でも `"lenet"` 値にアクセスできます。
