模式中的部署使用`as_view()` 類方法： ``` urlpatterns = [ url(r'^view/$', MyView.as_view(size=42)), ] ``` > 視圖參數的線程安全性 > > 傳遞給視圖的參數在視圖的每個實例之間共享。這表示不應該使用列表、字典或其它可變對象作為視圖的參數。如果你真這么做而且對共享的對象做過修改，某個用戶的行為可能對后面訪問同一個視圖的用戶產生影響。傳遞給`as_view()` 的參數將賦值給服務請求的實例。利用前面的例子，這表示對`MyView `的每個請求都可以使用 `self.size`。參數必須對應于在類中已經存在的屬性（`hasattr` 檢查可以返回`True`）。 ## 基礎視圖 VS. 通用視圖 ## 基于類的基礎視圖可以認為是父視圖，它們可以直接使用或者繼承它們。它們不能滿足項目中所有的需求，在這種情況下有Mixin 可以擴展基礎視圖的功能。 Django 的通用視圖建立在基礎視圖之上，用于作為經常用到的功能的快捷方式，例如顯示對象的詳細信息。它們提煉視圖開發中常見的風格和模式并將它們抽象，這樣你可以快速編寫常見的視圖而不用重復你自己。大部分通常視圖需要`queryset` 鍵，它是一個`查詢集` 實例；關于`查詢集`對象的更多信息，請參見執行查詢。 > 譯者：[Django
