Python 使用line_profiler对棱锥视图进行纵断面

使用line_profiler分析棱锥视图时遇到问题。由于Pyramid的

@view\u config

不能以典型方式与

@profile

一起使用，因此我修改了用于其他目的的视图装饰器：

def view_decorator_profile(view_callable):
    def inner(context, request):
        request._mso = MySpecialObject()
        log.debug('################## VIEW_CALLABLE %s', view_callable)
        profile.add_function(view_callable)
        return view_callable(context, request)
    return inner

我以标准金字塔的方式使用它：

@view_config(decorator=view_decorator_profile, route_name='myroute', renderer='....', permission='...')
def my_callable(...):

现在，分析运行。。除了金字塔似乎有一些黑魔法，而不是对

my_callable

进行分析，而是对

rendered_view

进行分析

见：

现在，我确信我在decorator中得到的

视图\u callable

是正确的：

log.debug

记录正确的名称（

my\u callable

）

如何使Pyramid/line_profiler配置文件可调用
