Question

我在使用line_profiler分析金字塔视图时遇到了问题。由于金字塔的@view_config不能与@profile一起使用，所以我修改了我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

我以标准的金字塔形式使用它：

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

现在，分析运行..除了金字塔似乎做了一些黑魔法而不是my_callable被分析，rendered_view被分析了！

现在，我很肯定我在装饰器中获得的view_callable是正确的：log.debug记录正确的名称（my_callable）。

如何制作Pyramid / line_profiler个人资料my_callable？

使用line_profiler来分析Pyramid视图
