* `table=True` sagt SQLModel, dass dies ein *Tabellenmodell* ist, es soll eine **Tabelle** in der SQL-Datenbank darstellen, es ist nicht nur ein *Datenmodell* (wie es jede andere reguläre Pydantic-Klasse wäre).

* `Field(primary_key=True)` sagt SQLModel, dass die `id` der **Primärschlüssel** in der SQL-Datenbank ist (Sie können mehr über SQL-Primärschlüssel in der SQLModel-Dokumentation erfahren).

FastAPI ile SSE akışı yapmak için, *path operation function* içinde `yield` kullanın ve `response_class=EventSourceResponse` olarak ayarlayın.

`EventSourceResponse`'u `fastapi.sse` içinden içe aktarın:

{* ../../docs_src/server_sent_events/tutorial001_py310.py ln[1:25] hl[4,22] *}

Yield edilen her öğe JSON olarak kodlanır ve bir SSE olayının `data:` alanında gönderilir.

## Стриминг SSE с FastAPI { #stream-sse-with-fastapi }

Чтобы стримить SSE с FastAPI, используйте `yield` в своей функции-обработчике пути и укажите `response_class=EventSourceResponse`.

Импортируйте `EventSourceResponse` из `fastapi.sse`:

{* ../../docs_src/server_sent_events/tutorial001_py310.py ln[1:25] hl[4,22] *}

Каждый возвращаемый через `yield` элемент кодируется как JSON и отправляется в поле `data:` события SSE.

Щоб транслювати SSE з FastAPI, використовуйте `yield` у вашій *функції операції шляху* і встановіть `response_class=EventSourceResponse`.

Імпортуйте `EventSourceResponse` з `fastapi.sse`:

{* ../../docs_src/server_sent_events/tutorial001_py310.py ln[1:25] hl[4,22] *}

Кожен елемент, повернений через `yield`, кодується як JSON і надсилається в полі `data:` події SSE.
