Hi,
You need to change WSGIApplication.wsgi_call to support this.
Here is what I'm doing
1. create a new file gapngo/wsgi.py, like so
#!/usr/bin/env python
#
from google.appengine.ext.webapp import *
from google.appengine.ext.webapp.util import run_wsgi_app
def wsgi_call(self, environ, start_response):
"""Called by WSGI when a request comes in."""
request = Request(environ)
response = Response()
# placeholder for middleware
request.blue = "blue"
WSGIApplication.active_instance = self
handler = None
groups = ()
for regexp, handler_class in self._url_mapping:
match = regexp.match(request.path)
if match:
handler = handler_class()
handler.initialize(request, response)
groups = match.groups()
kwargs = match.groupdict()
break
self.current_request_args = groups
if handler:
try:
method = environ['REQUEST_METHOD']
if method == 'GET':
handler.get(*groups, **kwargs)
elif method == 'POST':
handler.post(*groups, **kwargs)
elif method == 'HEAD':
handler.head(*groups, **kwargs)
elif method == 'OPTIONS':
handler.options(*groups, **kwargs)
elif method == 'PUT':
handler.put(*groups, **kwargs)
elif method == 'DELETE':
handler.delete(*groups, **kwargs)
elif method == 'TRACE':
handler.trace(*groups, **kwargs)
else:
handler.error(501)
except Exception, e:
handler.handle_exception(e, self.__debug)
else:
response.set_status(404)
response.wsgi_write(start_response)
return ['']
def run_gapngo_app(application):
WSGIApplication.__call__ = wsgi_call
run_wsgi_app(application)
2. In your views make the following changes
import gapngo.wsgi as wsgi
.....
def get(self, *args, **kwargs):
.....
wsgi.run_gapngo_app(application)
3. Now access your named regex groups as kwargs.get("blah")
Also note there is a placeholder for calling middleware.
