Missing configuration keys for "webapp2_extras.sessions": ['secret_key']

Question

I added webapp2 sessions to my appengine project, which uses webapp2 to process requests and django for templates.

Following this page , I added the following to my script

import webapp2 from webapp2_extras import sessions class BaseHandler(webapp2.RequestHandler): def dispatch(self): # Get a session store for this request. self.session_store = sessions.get_store(request=self.request) try: # Dispatch the request. webapp2.RequestHandler.dispatch(self) finally: # Save all sessions. self.session_store.save_sessions(self.response) @webapp2.cached_property def session(self): # Returns a session using the default cookie key. return self.session_store.get_session() config = {} config['webapp2_extras.sessions'] = { 'secret_key': 'my-super-secret-key', } 

However, now I get the following error

 Traceback (most recent call last): File "/home/user/google_appengine/lib/webapp2/webapp2.py", line 1536, in __call__ rv = self.handle_exception(request, response, e) File "/home/user/google_appengine/lib/webapp2/webapp2.py", line 1530, in __call__ rv = self.router.dispatch(request, response) File "/home/user/google_appengine/lib/webapp2/webapp2.py", line 1278, in default_dispatcher return route.handler_adapter(request, response) File "/home/user/google_appengine/lib/webapp2/webapp2.py", line 1102, in __call__ return handler.dispatch() File "/home/user/sites/project2n/main.py", line 804, in dispatch self.session_store = sessions.get_store(request=self.request) File "/home/user/google_appengine/lib/webapp2/webapp2_extras/sessions.py", line 454, in get_store store = request.registry[key] = factory(request) File "/home/user/google_appengine/lib/webapp2/webapp2_extras/sessions.py", line 308, in __init__ required_keys=('secret_key',)) File "/home/user/google_appengine/lib/webapp2/webapp2.py", line 1361, in load_config self._validate_required(key, config, required_keys) File "/home/user/google_appengine/lib/webapp2/webapp2.py", line 1375, in _validate_required 'Missing configuration keys for %r: %r.' % (key, missing)) Exception: Missing configuration keys for 'webapp2_extras.sessions': ['secret_key'] 

I set the secret key using config. I do not use anything for sessions. Others are imported

 import os,sys, string, time, sha, Cookie from django.template import Context, Template from django.template.loader import get_template 

Answer 1

You need to include this configuration somewhere, for example, in the created WSGI application:

 app = webapp2.WSGIApplication([('/path', MyHandler), config=config, debug=True) 

Answer 2

The order is important:

 config = {} config['webapp2_extras.sessions'] = { 'secret_key': 'my-super-secret-key', } app = webapp2.WSGIApplication([ ('/', HomeHandler), ], config=config)
