class BookConfig():     list_display = ['title','price','nid','publish']     links_display=['title']     search_conditon = ['title','price']     def delete_action(self,qu):         print(qu)         print(123)     delete_action.desc='批量删除'     def init_action(self):         pass     init_action.desc='批量初始化'     actions=[delete_action,init_action] book=BookConfig() func=getattr(BookConfig,'delete_action') print(func(book,'qunima')) print(book.delete_action('qunima')) 当得到BookCongfig的方法时，只是一个方法，不知道是哪个对象要调用它，

print(func(book,'qunima'))所以要传self 如果是

func=getattr(book,'delete_action') 就不要传对象，因为已经把book传进去了，已经知道是哪个对象调用了， 就可以直接fun（'去你妈'）
