In diesem Fall wird **FastAPI** `__init__` nie berühren oder sich darum kümmern, wir werden es direkt in unserem Code verwenden.

## Eine Instanz erstellen { #create-an-instance }

Wir könnten eine Instanz dieser Klasse erstellen mit:

{* ../../docs_src/dependencies/tutorial011_an_py310.py hl[18] *}

Aber so können wir uns besser auf die Funktionsweise des **Dependency Injection** Systems konzentrieren.

### Eine Abhängigkeit erstellen, oder <abbr title="Das von dem abhängt, die zu verwendende Abhängigkeit">„Dependable“</abbr> { #create-a-dependency-or-dependable }

Konzentrieren wir uns zunächst auf die Abhängigkeit – die Dependency.

Es handelt sich einfach um eine Funktion, die die gleichen Parameter entgegennimmt wie eine *Pfadoperation-Funktion*:

### Unlimited "plug-ins" { #unlimited-plug-ins }

Or in other way, no need for them, import and use the code you need.

Any integration is designed to be so simple to use (with dependencies) that you can create a "plug-in" for your application in 2 lines of code using the same structure and syntax used for your *path operations*.

### Tested { #tested }

### Créer une classe `Enum` { #create-an-enum-class }

Importez `Enum` et créez une sous-classe qui hérite de `str` et de `Enum`.

</div>

Ayrıca `all` extras'ını şu şekilde kurduğunuzda da dahil gelir:

<div class="termy">

```console
$ pip install "fastapi[all]"
---> 100%
```

</div>

### `Settings` nesnesini oluşturun { #create-the-settings-object }

Pydantic'ten `BaseSettings` import edin ve bir alt sınıf (sub-class) oluşturun; tıpkı bir Pydantic model'inde olduğu gibi.

# to `docker exec` commands, e.g., 'T:\path', instead of 'C:\path',
# without having to replace the drive letter with C:\ every time.
# Such a workaround is not required on Linux, since it
# can create arbitrary paths within the container, e.g., '/t'.
# Note: This does not affect/work for `docker cp` commands.
RUN New-Item -ItemType directory -Path C:\drive_t; \

	return paths
