### Client Üretecine Vermeden Önce OpenAPI Spesifikasyonunu Ön İşlemek { #preprocess-the-openapi-specification-for-the-client-generator }

Üretilen kodda hâlâ bazı **tekrarlanan bilgiler** var.

Bu method'un **items** ile ilişkili olduğunu zaten biliyoruz; çünkü bu kelime `ItemsService` içinde var (tag'den geliyor). Ama method adında da tag adı önek olarak duruyor. 😕

- Bunun yerine ✨ **`Union[SomeType, None]` kullanın** ✨.

İkisi de eşdeğer ve temelde aynıdır; ancak "**optional**" kelimesi değerin isteğe bağlı olduğunu ima eder. Oysa aslında " `None` olabilir" demektir; değer isteğe bağlı olmasa ve hâlâ zorunlu olsa bile.

Bence `Union[SomeType, None]` ne demek istediğini daha açık anlatır.

Burada mesele sadece kelimeler ve isimler. Ancak bu kelimeler sizin ve ekip arkadaşlarınızın koda bakışını etkileyebilir.
