能否从实际使用经验的角度谈谈 Django function-based views 和 class-based views 两种 View 的优缺点或使用场景?

    1. function-based views (FBVs)
    def sprinkle_list(request):
    ____request = check_sprinkles(request)
    ________return render(request, "sprinkles/sprinkle_list.html", {"sprinkles": Sprinkle.objects.all()})

    2. class-based views (CBVs)
    class SprinkleDetail(DetailView):
    ____model = Sprinkle
    ____def dispatch(self, request, *args, **kwargs):
    ________request = check_sprinkles(request)
    ________return super(SprinkleDetail, self).dispatch(request, *args, **kwargs)

    缩进表示不出来。。。用下划线替代了。。

    我用 function-based views 更多一些。
    大多情况下 function-based views 数据流更清晰一些。
    不过 function-based views 的扩展性比较差,写通用的 views 会有些困难。

    就上面的场景来说,我觉得都可以,主要看习惯。
