// If no system-wide time zone database can be found a bundled version of the database is used instead.
  // If the time zone name becomes invalid during the lifetime of a CronJob or due to a change in host

In fact, in some cases, it will even have **two JSON Schemas** in OpenAPI for the same Pydantic model, for input and output, depending on if they have **default values**.

Let's see how that works and how to change it if you need to do that.

## Pydantic Models for Input and Output

Let's say you have a Pydantic model with default values, like this one:

### Configure Keycloak Realm

- Go to Clients
  - Click on account
    - Settings
    - Change `Access Type` to `confidential`.
    - Save
  - Click on credentials tab
    - Copy the `Secret` to clipboard.
    - This value is needed for `MINIO_IDENTITY_OPENID_CLIENT_SECRET` for MinIO.

- Go to Users

```java
OkHttpClient client = new OkHttpClient.Builder()
    .connectionSpecs(Arrays.asList(ConnectionSpec.MODERN_TLS, ConnectionSpec.COMPATIBLE_TLS))
    .build();
```

                    assertThat(typeArguments[1].sourceName, equalTo("*"))
                }
            }
        }
    }

    @Test
    fun `includes function overrides that change signature, excludes overrides that don't`() {
        val jars = listOf(withClassJar("some.jar", AbstractCopyTask::class.java, CopySpecSource::class.java))

        apiTypeProviderFor(jars).use { api ->

!!! note "技术细节"

    也可以使用 `from starlette import status`。

    为了让开发者更方便，**FastAPI** 提供了与 `starlette.status` 完全相同的 `fastapi.status`。但它直接来自于 Starlette。

## 更改默认状态码

    ```Python hl_lines="2  5  9  13  47  65  106  108-116  122-125  129-135  140  156"
    {!> ../../../docs_src/security/tutorial005.py!}
    ```

Now let's review those changes step by step.

## OAuth2 Security scheme

The first change is that now we are declaring the OAuth2 security scheme with two available scopes, `me` and `items`.
