!!! tip
    Peewee creates several magic attributes.

    It will automatically add an `id` attribute as an integer to be the primary key.

    It will chose the name of the tables based on the class names.

    For the `Item`, it will create an attribute `owner_id` with the integer ID of the `User`. But we don't declare it anywhere.

## Create the Pydantic models

Now let's check the file `sql_app/schemas.py`.

↩️ ➡ 🔢 `item_id` ✔️ 💲 `"foo"`, ❔ 🚫 `int`.

これは、パスパラメータ `item_id` が `int` ではない値 `"foo"` だからです。
