I am trying to grasp the concept of persistant data in django channels
<https://channels.readthedocs.io/en/stable/getting-started.html#persisting-data>.
I have searched the reference and other parts but didn't clear my
confusion. I would really appreciate if you help me understand better.
consumers.py:
@channel_sessiondef ws_connect(message):
# Work out room name from path (ignore slashes)
room = message.content['path'].strip("/")
# Save room in session and add us to the group
message.channel_session['room'] = room
Group("chat-%s" % room).add(message.reply_channel)
Q.1 In the above line message.channel_session['room'], is the room another
property of the message? Like it tells which session the message belongs to?
@channel_sessiondef ws_message(message):
Group("chat-%s" % message.channel_session['room']).send({
"text": message['text'],
})
Q2. In the line Group("chat-%s" % message.channel_session['room']).send({,
why are we not using the *room* variable like in the ws_connect() function,
but instead we are using the channels_session?
@channel_sessiondef ws_disconnect(message):
Group("chat-%s" %
message.channel_session['room']).discard(message.reply_channel)
Q3. Same like above, why are we not using the *room* variable to discard
from the group? Also is it not neccesary to remove the room from the
session?
