在某些情境中，從相依（dependency）提供設定，會比在各處使用一個全域的 `settings` 物件更有用。

這在測試時特別實用，因為你可以很容易用自訂的設定來覆寫一個相依。

### 設定檔 { #the-config-file }

延續前一個範例，你的 `config.py` 可以像這樣：

{* ../../docs_src/settings/app02_an_py310/config.py hl[10] *}

注意現在我們不再建立預設實例 `settings = Settings()`。

### 主應用程式檔案 { #the-main-app-file }

現在我們建立一個相依，回傳新的 `config.Settings()`。

{* ../../docs_src/settings/app02_an_py310/main.py hl[6,12:13] *}
