方法的参数未传递给d

Question

嘿，我有一个定义如下的方法：

from x.y import util
class my_Class(some_object):
    @util.myDecorator
    def foo(self, log_file):
    '''
    Test that search entered into the search bar is the search being
    executed in the job.
    '''
    self.some_page.open()
    textarea = self.some_page.searchbar

    searchbar.run_search(log_file.search_string)
    self.browser.capture_screenshot()
    self.some_page.jobstatus.wait_for_job_complete()

    self.verify_equals(
        self.some_page.jobstatus.event_count,
        log_file.event_count,
        "Event count doesn't seem to be right.")

装饰师在档案里利用率你知道吗

def mydecorator(func):
    def timeit(*args, **kwargs):
        start_time = time.time()
        ret=func(*args, **kwargs)
        end_time = time.time()
        print end_time - start_time
        return ret
    return timeit

当我尝试执行代码时，它在ret=func(*args, **kwargs)失败，并显示错误消息

TypeError: foo() takes exactly 2 arguments (1 given)

• 我打印了*args的内容（使用','.join(str(each) for each in args)）以查看它包含的内容，然后打印出来

<....my_Class object at ...>

对于只有一个arg（self）的方法，decorator工作得很好。我是不是漏了什么？你知道吗
