如何使用基於django類的視圖和裝飾器將數據附加到視圖方法？

Question

我有以下裝飾器：

def my_decorator(setting_value):

    def actual_decorator(func):
        func.my_setting = setting_value
        return func

    return actual_decorator

我正在嘗試像這樣的上下文處理器中讀取my_setting ：

# Resolve the url
try:
    page_resolve = resolve(request.path_info)
except Resolver404:
    return {}

# Get the page view function
page_view = page_resolve.func

if (page_view.my_setting):
    return extra_context_data
else
    return {}

使用CBV時，整個方案會分崩離析。 如何使裝飾器與FBV和CBV兼容？

將裝飾器應用於dispatch功能：

class MyView(View):
    @my_decorator
    def dispatch(self, *args, **kwargs):
        return super(MyView, self).dispatch(*args, **kwargs)
