**FastAPI**, normal dependency'lerde olduğu gibi her ikisinde de doğru şekilde davranır.

///

## `yield` ve `try` ile Bir Dependency { #a-dependency-with-yield-and-try }

`yield` kullanan bir dependency içinde bir `try` bloğu kullanırsanız, dependency kullanılırken fırlatılan (raised) herhangi bir exception'ı alırsınız.

## Instance'ı dependency olarak kullanma { #use-the-instance-as-a-dependency }

Sonra `Depends(FixedContentQueryChecker)` yerine `Depends(checker)` içinde bu `checker`'ı kullanabiliriz. Çünkü dependency, class'ın kendisi değil, `checker` instance'ıdır.

Ve dependency çözülürken **FastAPI** bu `checker`'ı şöyle çağırır:

```Python
checker(q="somequery")
```

## Dependency ağacı ve scope'lar { #dependency-tree-and-scopes }

Bu dependency ağacını ve scope'ları tekrar gözden geçirelim.
