# Alt Bağımlılıklar { #sub-dependencies }

**Alt bağımlılıkları** olan bağımlılıklar oluşturabilirsiniz.

İhtiyacınız olduğu kadar **derine** gidebilirler.

Bunları çözme işini **FastAPI** üstlenir.

## İlk bağımlılık "dependable" { #first-dependency-dependable }

Şöyle bir ilk bağımlılık ("dependable") oluşturabilirsiniz:

{* ../../docs_src/dependencies/tutorial005_an_py310.py hl[8:9] *}

# Подзависимости { #sub-dependencies }

Вы можете создавать зависимости, которые имеют **подзависимости**.

Их **вложенность** может быть любой глубины.

**FastAPI** сам займётся их управлением.

## Первая зависимость { #first-dependency-dependable }

Можно создать первую зависимость следующим образом:

{* ../../docs_src/dependencies/tutorial005_an_py310.py hl[8:9] *}

# Sous-dépendances { #sub-dependencies }

Vous pouvez créer des dépendances qui ont des sous-dépendances.

Elles peuvent être aussi profondes que nécessaire.

**FastAPI** se chargera de les résoudre.

## Créer une première dépendance « dependable » { #first-dependency-dependable }

Vous pouvez créer une première dépendance (« dependable ») comme :

{* ../../docs_src/dependencies/tutorial005_an_py310.py hl[8:9] *}

# Subdependências { #sub-dependencies }

Você pode criar dependências que possuem **subdependências**.

Elas podem ter o nível de **profundidade** que você achar necessário.

O **FastAPI** se encarrega de resolver essas dependências.

## Primeira dependência "dependable" { #first-dependency-dependable }

Você pode criar uma primeira dependência ("dependable") dessa forma:

{* ../../docs_src/dependencies/tutorial005_an_py310.py hl[8:9] *}

func (ps *PubSub[T, M]) Publish(item T) {
	ps.RLock()
	defer ps.RUnlock()
	for _, sub := range ps.subs {
		if sub.types.Contains(Mask(item.Mask())) && (sub.filter == nil || sub.filter(item)) {
			select {
			case sub.ch <- item:
			default:
			}
		}
	}
}

This is different from using an `APIRouter` as a mounted application is completely independent. The OpenAPI and docs from your main application won't include anything from the mounted application, etc.

You can read more about this in the [Advanced User Guide](../advanced/index.md).
