And these models are all sharing a lot of the data and duplicating attribute names and types.

We could do better.

We can declare a `UserBase` model that serves as a base for our other models. And then we can make subclasses of that model that inherit its attributes (type declarations, validation, etc).

All the data conversion, validation, documentation, etc. will still work as normally.

				// Removes the region from ARN if server region is not set
				if q2.ARN.region != "" && q1.ARN.region == "" {
					q2.ARN.region = ""
				}
				if reflect.DeepEqual(q1, q2) {
					return &ErrDuplicateQueueConfiguration{q1}
				}
			}
		}

Post to a Server
----------------

This program posts data to a service. [Full source][post_example].

```java
public static final MediaType JSON = MediaType.get("application/json");

OkHttpClient client = new OkHttpClient();

<font color="#4E9A06">INFO</font>:     Started reloader process [<font color="#34E2E2"><b>2265862</b></font>] using <font color="#34E2E2"><b>WatchFiles</b></font>
<font color="#4E9A06">INFO</font>:     Started server process [<font color="#06989A">2265873</font>]
<font color="#4E9A06">INFO</font>:     Waiting for application startup.
<font color="#4E9A06">INFO</font>:     Application startup complete.

    InetAddress client = InetAddresses.forString(clientStr);

    assertEquals(port, teredo.getPort());

Der wesentliche Punkt ist, dass der `sub`-Schlüssel in der gesamten Anwendung eine eindeutige Kennung haben sollte, und er sollte ein String sein.

## Es testen

Führen Sie den Server aus und gehen Sie zur Dokumentation: <a href="http://127.0.0.1:8000/docs" class="external-link" target="_blank">http://127.0.0.1:8000/docs</a>.

Die Benutzeroberfläche sieht wie folgt aus:
