我怎么能有decorator.other？

Question

这是我试图用我的代码完成的结构。我想使用registry.filter和registry.action来加载我正在构建的应用程序的过滤器和操作。我知道我可以将它们分成两个不同的装饰器。

def registry():
    def filter(*expected_args):
        def decorator(func):
            def wrapper(*args, **kwargs):
                return func(*args, **kwargs)
            return wrapper
        return decorator

    def filter(*expected_args):
        def decorator(func):
            def wrapper(*args, **kwargs):
                return func(*args, **kwargs)
            return wrapper
        return decorator


@registry.filter({

})
def my_filter():
    print "Hello World!"

@registry.action({

})
def my_action():
    print "Hello World!"

if __name__ == "__main__":
    my_filter()
    my_action()

每当我运行我的代码时，都会收到此错误：

Traceback (most recent call last):
  File "/Users/chris/Documents/Content-Management/registry.py", line 19, in <module>
    @registry.filter({
AttributeError: 'function' object has no attribute 'filter'
