## Create models

Create Pydantic models for:

* Notes to be created (`NoteIn`).
* Notes to be returned (`Note`).

```Python hl_lines="31-33  36-39"
{!../../../docs_src/async_sql_databases/tutorial001.py!}
```

By creating these Pydantic models, the input data will be validated, serialized (converted), and annotated (documented).

    assertThat(formEncode(35)).isEqualTo("%23")
    assertThat(formEncode(36)).isEqualTo("%24")
    assertThat(formEncode(37)).isEqualTo("%25")
    assertThat(formEncode(38)).isEqualTo("%26")
    assertThat(formEncode(39)).isEqualTo("%27")
    assertThat(formEncode(40)).isEqualTo("%28")
    assertThat(formEncode(41)).isEqualTo("%29")
    assertThat(formEncode(42)).isEqualTo("*")
    assertThat(formEncode(43)).isEqualTo("%2B")

### Create a *path operation* to test static files

Now, to be able to test that everything works, create a *path operation*:

### Test Static Files UI

## 多个模型

下面的代码展示了不同模型处理密码字段的方式，及使用位置的大致思路：

=== "Python 3.10+"

    ```Python hl_lines="7  9  14  20  22  27-28  31-33  38-39"
    {!> ../../../docs_src/extra_models/tutorial001_py310.py!}
    ```

=== "Python 3.8+"

    ```Python hl_lines="9  11  16  22  24  29-30  33-35  40-41"
    {!> ../../../docs_src/extra_models/tutorial001.py!}

Ниже изложена основная идея того, как могут выглядеть эти модели с полями для паролей, а также описаны места, где они используются:

    longValues.add(Integer.MAX_VALUE + 1L, Long.MAX_VALUE - 1L, Long.MAX_VALUE);

    // Now add values near 2^N for lots of values of N.
    for (int exponent : asList(32, 33, 39, 40, 41, 47, 48, 49, 55, 56, 57)) {
      long x = 1L << exponent;
      longValues.add(x, x + 1, x - 1);
    }
    longValues.add(194368031998L).add(194368031999L); // sqrt(2^75) rounded up and down

Hier der generelle Weg, wie die Modelle mit ihren Passwort-Feldern aussehen könnten, und an welchen Orten sie verwendet werden würden.
