Теперь вы знаете, что когда они понадобятся, вы сможете использовать их в **FastAPI**.

### `regex` из Pydantic v1 вместо `pattern` { #pydantic-v1-regex-instead-of-pattern }

До Pydantic версии 2 и до FastAPI 0.100.0 этот параметр назывался `regex`, а не `pattern`, но сейчас он устарел.

Вы всё ещё можете встретить такой код:
