### Eine *Pfadoperation* hinzufügen

Wir können *Pfadoperationen* auch direkt zur `FastAPI`-App hinzufügen.

Hier machen wir es ... nur um zu zeigen, dass wir es können 🤷:

```Python hl_lines="21-23" title="app/main.py"
{!../../docs_src/bigger_applications/app/main.py!}
```

und es wird korrekt funktionieren, zusammen mit allen anderen *Pfadoperationen*, die mit `app.include_router()` hinzugefügt wurden.

		participle.CaseInsensitive("Keyword"),
	)

	s := Select{}
	cases := []string{
		"select * from s3object where name > 2 or value > 1 or word > 2",
		"select s.word.id + 2 from s3object s",
		"select 1-2-3 from s3object s limit 1",
	}
	for i, tc := range cases {
		err := p.ParseString(tc, &s)
		if err != nil {
			t.Fatalf("%d: %v", i, err)
		}

		// repr.Println(s, repr.Indent("  "), repr.OmitEmpty(true))

      parameters:
        - name: seed
          in: query
          description: Random seed to return popular words
          required: false
          schema:
            type: string
            example: 123
        - name: label
          in: query
          description: Filtered label name
          required: false
          style: form
          explode: true
          schema:
            type: array

### Include a *path operation*

We can also add *path operations* directly to the `FastAPI` app.

Here we do it... just to show that we can 🤷:

```Python hl_lines="21-23" title="app/main.py"
{!../../docs_src/bigger_applications/app/main.py!}
```

and it will work correctly, together with all the other *path operations* added with `app.include_router()`.

  public void testNullPointers() {
    NullPointerTester tester = new NullPointerTester();
    tester.testAllPublicStaticMethods(ImmutableList.class);
    tester.testAllPublicInstanceMethods(ImmutableList.of(1, 2, 3));
  }

  @J2ktIncompatible
  @GwtIncompatible // SerializableTester
  public void testSerialization_empty() {
    Collection<String> c = ImmutableList.of();

  }

  public void testGetExitingExecutorService_executorSetToUseDaemonThreads() {
    TestApplication application = new TestApplication();
    ThreadPoolExecutor executor =
        new ThreadPoolExecutor(1, 2, 3, SECONDS, new ArrayBlockingQueue<Runnable>(1));
    assertNotNull(application.getExitingExecutorService(executor));
    assertTrue(executor.getThreadFactory().newThread(EMPTY_RUNNABLE).isDaemon());
  }
