Solve the following python programming problem given the following code:
@ request_method_decorator 
def _get_template_request(self, url_template, values = { 
    
}, **kwargs) : 
    "Generate an HttpRequest from a uri-template.

        This will replace each '{variable}' in the template with the
        value from kwargs['variable'], or if it does not exist, the
        value from values['variable']. The resulting url is used to
        create an HttpRequest.
        " 
    def get_template_value(m) : 
        try : 
            return str ((kwargs.pop (m.group ('key'), None) or values [m.group ('key')])) 
except KeyError : 
            raise ValueError (('Template was not provided a value for "%s"' % m.group ('key'))) 
url = self._TEMPLATE_PARAM_RE.sub (values, url_template) 
    return HttpRequest (url, query_args = kwargs) 

    
    

    Fix the buggy line: url = self._TEMPLATE_PARAM_RE.sub (values, url_template)
assistant
#Here is Python code to fix the buggy line: url = self.

url = self._TEMPLATE_PARAM_RE.sub (def get_template_value(, url_template)
