## Forbid Extra Form Fields { #forbid-extra-form-fields }

In some special use cases (probably not very common), you might want to **restrict** the form fields to only those declared in the Pydantic model. And **forbid** any **extra** fields.

This is supported since FastAPI version `0.114.0`. 🤓

`response_model`’in "decorator" metodunun (`get`, `post` vb.) bir parametresi olduğuna dikkat edin. Body ve diğer parametreler gibi, sizin *path operation function*’ınızın parametresi değildir.

///

`response_model`, Pydantic model field’ı için declare edeceğiniz aynı tipi alır; yani bir Pydantic model olabilir ama örneğin `List[Item]` gibi Pydantic model’lerden oluşan bir `list` de olabilir.
