class BookConfig():
list_display = ['title','price','nid','publish']

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'）
