Python 如何将decorator参数注入docstring？

我在API中使用了一个特定的装饰器模式，它看起来像这样（简化）：

我正在使用斯芬克斯生成我的文档。我想将decorator的参数注入到它所修饰的函数的docstring中。对于上面的示例，我希望文档如下所示：

    mypackage.something module

    mypackage.something.double(x)

    This endpoint doubles the number you give it.

    Attributes:
        path: /double
        method: GET

    Args:
        x: (int) the number you want to double

    Returns:
        x_double: (int) x * 2

我怎样才能做到这一点？我正在考虑编写一个脚本，将这些内容注入到生成的文档中，但我想知道是否有更简单的方法

另外，是的，装饰程序正在使用

functools.wrapps

这里的棘手部分是在描述和参数之间插入属性。但是装饰程序不能从

输入

和

输出

参数中生成

参数

和`

返回

部分吗？然后您可以简单地将生成的字符串附加到

double.\uu doc\uuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu

@chepner我知道你指的是什么，这应该行得通！这里棘手的部分是在描述和参数之间插入属性。但是装饰程序不能从
