### Dependency injection

FastAPI'ın inanılmaz derecede kullanımı kolay, fakat inanılmaz derecede güçlü <abbr title='"components", "resources", "services", "providers" olarak da bilinen'><strong>Dependency Injection </strong></abbr> sistemi var.

* Dependencylerin bile dependencies'i olabiliyor, FastAPI bunun  için **graph of "dependency"** yaratıyor.

            lenient().doNothing().when((DcerpcHandle) handle).close();

            // Setup close to call real method which will then call our mocked components
            doCallRealMethod().when(handle).close();

            handle.close();

            verify(mockSmbPipeHandleInternal).close();
            verify(mockSmbNamedPipe).close();
        }

## Pydantic v1 no v2 { #pydantic-v1-in-v2 }

O Pydantic v2 inclui tudo do Pydantic v1 como um submódulo `pydantic.v1`.

Isso significa que você pode instalar a versão mais recente do Pydantic v2 e importar e usar os componentes antigos do Pydantic v1 a partir desse submódulo, como se tivesse o Pydantic v1 antigo instalado.

- If upgrading Cluster Federation components from 1.3.x, please ensure your cluster name is a valid DNS label (#30956, @nikhiljindal)
- kubelet's `--config` flag has been deprecated, use `--pod-manifest-path` instead (#29999, @mtaufen)

### Внедрение зависимостей { #dependency-injection }

FastAPI включает в себя чрезвычайно простую в использовании, но чрезвычайно мощную систему <abbr title='известную как: "components", "resources", "services", "providers"'><strong>Внедрения зависимостей</strong></abbr>.

* Даже зависимости могут иметь зависимости, создавая иерархию или **«граф» зависимостей**.
