Django Channel Error

2017-12-07 Thread Maitreya Verma

I am following this tutorial 
 to learn 
django channels. 
The following procedure was used :

   - Add the following code in settings.py
   redis_host=os.environ.get('REDIS_HOST','localhost')
   
   CHANNEL_LAYERS={
   "default":{
   "BACKEND":"asgi_redis.RedisChannelLayer",
   "CONFIG":{
   "hosts":[(redis_host),6379],
   },
   "ROUTING":'channelproj.routing.channel_routing',
   },
   }
   
   - Create a file routing.py and add the following code
   from channels import route
   # This function will display all messages received in the console
   def message_handler(message):
   print(message['text'])
   
   channel_routing = [
   route("websocket.receive", message_handler),
   ]
   
   - run server using python manage.py runserver and then try to connect to 
   server using  ws.connect("ws://localhost:8000/")

I am getting the following error
websocket._exceptions.WebSocketBadStatusException: Handshake status 200

What can be the reason for this error and how can it be rectified?

That error means you are not actually running a websocket-capable server.
Did you add "channels" to INSTALLED_APPS?

Re: Saving webp image near jpg version

Actually, you need to use any background library ( like 
https://github.com/arteria/django-background-tasks/ ) for processing 
large-time operations such as image processing.

You can have a look at my project:

It is simple and uses the built in Django Auth module.

uwsgi stats middleware for Django

2017-12-07 Thread Etienne Robillard


Hi,

I would like to access the uWSGI stats API from within Django by 
creating a custom WSGI middleware.


Could it be possible to compute the number of requests currently being 
used by uWSGI workers in Python/Django ?


Ideally, i could then retrieve the active connections in use in a 
standard Django view:


def someview(request):

    # retrieve the number of active requests (connections)

    connections = request.environ['uwsgi.requests']


What do you think?


Etienne

Hi.

There isn't anything built in to satisfy your needs but you can easily
create such a mechanism with few models and helper funcs or methods.

Re: uwsgi stats middleware for Django

2017-12-07 Thread Ádler Oliveira Silva Neves

Sounds like you want retrieving statistics from uWSGI's stats server.

http://uwsgi-docs.readthedocs.io/en/latest/StatsServer.html

In order to get that JSON via HTTP requests, your server ".ini" should
receive extra arguments to start an stats server listening to the
specified port and application must be somehow aware of such port
number, which has a side-effect of increasing coupling.

Sincerely,

Adler
