sending "async" status update and final result

[sam-thecoder]

I have a problem wrapping my mind on the best way to implement this; I have this code in the consumers.py

import json
from channels import Group
from channels.sessions import channel_session

# Connected to websocket.connect
@channel_session
def ws_connect(message, key):
    # Accept connection
    message.reply_channel.send({"accept": True})
    # Parse the query string
    print message

    #Get key and set using key
    message.channel_session["key"] = key
    
    #Set with key
    Group("p-%s"%key).add(message.reply_channel)
    
    #else:
        # Close the connection.
        #message.reply_channel.send({"close": True})

# Connected to websocket.receive
@channel_session
def ws_message(message, key):
    reply = {}
    json_response = json.dumps(reply)
    Group("p-%s"%key).send({
        "text": json_response,
    })

# Connected to websocket.disconnect
@channel_session
def ws_disconnect(message, key):
    Group("p-%s"%key).discard(message.reply_channel)

and I could either move it or import it in my program flow is for an image processing which should return the status of the process and final result.

for _ in range(x):
    #insert code for ws_connect
    ...
    if counter%100 == 0:
        #send update (no further data is needed from user so it would be a ws_send like function)

#send proccessed result (ws_send)
#ws_disconnect

honestly this is far easier than celery and I hope you can help me finish setting it up.
also there's a part in you're docs where you have an import that doesn't work in python 2.7

In [1]: from urllib.parse import parse_qs
---------------------------------------------------------------------------
ImportError                               Traceback (most recent call last)
<ipython-input-1-884805ae250f> in <module>()
----> 1 from urllib.parse import parse_qs

ImportError: No module named parse

The import is for Python 3, which is what the docs are written for - you'll have to adapt it for Python 2.

I'll answer the more open-ended question on the mailing list, since this is not the right place.
