## Chạy mã

Tất cả các code block có thể được sao chép và sử dụng trực tiếp (chúng thực chất là các tệp tin Python đã được kiểm thử).

Để chạy bất kì ví dụ nào, sao chép code tới tệp tin `main.py`, và bắt đầu `uvicorn` với:

<div class="termy">

```console
$ uvicorn main:app --reload

	DB.Model(&product).Select("Name", "Code", "Price").Updates(Product3{Name: "Product New4", Code: ""})
	if product.Name != "Product New4" || product.Price != 320 || product.Code != "" {
		t.Errorf("invalid data after update, got %+v", product)
	}

	DB.Model(&product).UpdateColumns(Product3{Code: "L1215"})
	if product.Price != 320 || product.Code != "L1215" {
		t.Errorf("invalid data after update, got %+v", product)

    return current;
  }

## `APIRouter`

Nehmen wir an, die Datei, die nur für die Verwaltung von Benutzern zuständig ist, ist das Submodul unter `/app/routers/users.py`.

Sie möchten die *Pfadoperationen* für Ihre Benutzer vom Rest des Codes trennen, um ihn organisiert zu halten.

Aber es ist immer noch Teil derselben **FastAPI**-Anwendung/Web-API (es ist Teil desselben „Python-Packages“).

Sie können die *Pfadoperationen* für dieses Modul mit `APIRouter` erstellen.
