* `routers` subpackage’ini bul (`app/routers/` dizini)...
* ve buradan `items` submodule’ünü (`app/routers/items.py`) ve `users` submodule’ünü (`app/routers/users.py`) import et...

`items` module’ünün içinde `router` adında bir değişken vardır (`items.router`). Bu, `app/routers/items.py` dosyasında oluşturduğumuz aynı değişkendir; bir `APIRouter` nesnesidir.

    /**

And Python has a special data type for sets of unique items, the `set`.

Then we can declare `tags` as a set of strings:

{* ../../docs_src/body_nested_models/tutorial003_py310.py hl[12] *}

With this, even if you receive a request with duplicate data, it will be converted to a set of unique items.

And whenever you output that data, even if the source had duplicates, it will be output as a set of unique items.

애플리케이션의 "items"를 처리하는 전용 endpoint들도 `app/routers/items.py` 모듈에 있다고 해봅시다.

여기에는 다음에 대한 *path operations*가 있습니다:

* `/items/`
* `/items/{item_id}`

구조는 `app/routers/users.py`와 완전히 동일합니다.

하지만 우리는 조금 더 똑똑하게, 코드를 약간 단순화하고 싶습니다.

이 모듈의 모든 *path operations*에는 다음이 동일하게 적용됩니다:

* 경로 `prefix`: `/items`.
* `tags`: (태그 하나: `items`).
* 추가 `responses`.

    /**
     * Returns the last ExecutionPlanItem in the supplied phase. If no items are in the specified phase,
     * the closest executionPlanItem from an earlier phase item will be returned.
     *
     * @param requestedPhase the requested phase
     *                       The execution plan item
     * @return The ExecutionPlanItem or null if none can be found
     */

	tx.AutoMigrate(&ItemParent{}, &ItemChild{})

	item := ItemChild{
		Name: "name",
		ItemParent: ItemParent{
			Logo: "logo",
		},
	}
	if err := tx.Create(&item).Error; err != nil {
		t.Fatalf("failed to create items, got error: %v", err)
	}

	// test replace

En muchos casos tu app de FastAPI será más grande, y probablemente usarás tags para separar diferentes grupos de *path operations*.

Por ejemplo, podrías tener una sección para **items** y otra sección para **users**, y podrían estar separadas por tags:

{* ../../docs_src/generate_clients/tutorial002_py310.py hl[21,26,34] *}
