灵活的正则表达式 url，Django
我尝试做灵活的网址。我是这样做的
url(r'^(&\w*)?/?$', direct_to_template,
{'template': 'basic.djhtml'}),
get_absolute_url
def get_absolute_url(self):
return "/&%s" % self.human_redble_url
问题是错误：
direct_to_template() 获得关键字参数“template”的多个值
这是什么意思？我该如何解决它？
在Python交互式解释器中，这个正则表达式可以工作
>>> import re
>>> reg = re.compile('^(&\w*)?/?$')
>>> result = reg.match('&post1')
>>> result
<_sre.SRE_Match object at 0xb77098a0>
>>> wrong = reg.match('aergsr')
>>> print wrong
None
>>> reg.match('post1')
>>> print reg.match('post1')
None
>>> print reg.match('&post1/')
<_sre.SRE_Match object at 0xb77097a0>
>>> print reg.match('&post1:')
None
I try to do flexible url. I did it this way
url(r'^(&\w*)?/?
get_absolute_url
def get_absolute_url(self):
return "/&%s" % self.human_redble_url
The problem is an error:
direct_to_template() got multiple values for keyword argument 'template'
What does it mean? How could I fix it?
In Python interactive interpretor this regexp works
>>> import re
>>> reg = re.compile('^(&\w*)?/?
, direct_to_template,
{'template': 'basic.djhtml'}),
get_absolute_url

我不明白那个＆符号在那里做什么，但没关系。
我怀疑问题是您没有在 URL 中使用命名组。因此捕获的字符串作为第一个位置参数发送到视图函数，它实际上是
template，因此它与 template 关键字 arg 冲突。使用命名组 -
&(?P\w*)?/?$ - 它应该可以工作。I don't understand what that ampersand is doing there, but never mind.
I suspect the problem is that you have not used named groups in your URL. So the captured string is being sent through to the view function as the first positional argument, which is actually
template, so it conflicts with the template keyword arg.Use a named group -
&(?P<my_arg>\w*)?/?$- and it should work.
