看到这样一个Django 代码片段

from django.views.generic.create_update import create_object

@login_required
def create_vendor(request):
    return create_object(request,
        model = Vendor,
        post_save_redirect = '/vendor/list/'
    )

其中@的用法是 django 特有的，还是python 的用法？

是python 2.4新增的一个特性，叫decorator，网上有相关的资料，我的blog中也有描述可以查一查。

哎，其实一句话就可以说清楚了，呵呵：

@decorater
def func(...):
    pass

等价于：

def func(...):
    pass
func = decorater(func)
