### Die `APIRouter` für `users` und `items` inkludieren

Inkludieren wir nun die `router` aus diesen Submodulen `users` und `items`:

```Python hl_lines="10-11" title="app/main.py"

```

/// info

`users.router` enthält den `APIRouter` in der Datei `app/routers/users.py`.

			[]interface{}{1},

				clause.Update{},
				clause.Set([]clause.Assignment{{clause.PrimaryColumn, 1}}),
				clause.Set([]clause.Assignment{{clause.Column{Name: "name"}, "jinzhu"}}),
			},
			"UPDATE `users` SET `name`=?",
			[]interface{}{"jinzhu"},
		},

## `APIRouter`

假设专门用于处理用户逻辑的文件是位于 `/app/routers/users.py` 的子模块。

你希望将与用户相关的*路径操作*与其他代码分开，以使其井井有条。
