## 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.

Возможно, вам понадобится, чтобы параметр содержал `/home/johndoe/myfile.txt` с ведущим слэшем (`/`).

В этом случае URL будет таким: `/files//home/johndoe/myfile.txt`, с двойным слэшем (`//`) между `files` и `home`.

Anda mungkin perlu parameter berisi `/home/johndoe/myfile.txt` di awali garis belakang (`/`).

Di kondisi ini, URL nya menjadi: `/files//home/johndoe/myfile.txt`, dengan dua garis belakang (`//`) di antara `files` dan `home`.
