    <p>I built a chat with django-socketio and I'm trying to use redis with it.</p> <p>I have a very simple event.py:</p> <pre><code> @events.on_message(channel='^channel-') def messages(request, socket, context, message): socket.send_and_broadcast_channel(message) </code></pre> <p>The chat works perfectly.</p> <p>Now I'm trying to implement redis:</p> <pre><code> @events.on_message(channel='^channel-') def messages(request, socket, context, message): r = redis.StrictRedis() r = r.pubsub() r.subscribe('chat') s = redis.Redis() s.publish('chat', message) for m in r.listen(): data = m['data'] print data </code></pre> <p>The message is published on the redis channel, but once I call .listen(), nothing works anymore. It looks like .listen() is 'blocking' everything. I can't even escape the server using ctr+C</p> <p>Any idea on how I can solve that? Thank you!</p> <p>EDIT:</p> <p>Here is what I have now:</p> <pre><code> def listener(self): r = redis.StrictRedis() r = r.pubsub() r.subscribe('chat') for m in r.listen(): message = m['data'] socket.send_and_broadcast_channel(message) @events.on_message() def messages(request, socket, context, message): r = redis.Redis() r.publish('chat', message) </code></pre> <p>Still doesn't work.</p> <p>In order redis to work with gevent(used by django-socketio), we have to start a Greenlet when the user subscribes. So we need to add something like that:</p> <pre><code> def on_subscribe(self, *args, **kwargs): self.spawn(self.listener) </code></pre> <p>But I didn't figure how to do that with django-socketio given that we have to use an event </p> <pre><code> @event.on_connect() def connect(request, socket, context) </code></pre> <p>But I can't pass an argument 'self'. So I can't use 'self.spawn(self.listener)', and I don't know how I could do differently</p>

    2. CO@OscarDavidArbeláez Yes, but I would like to implement redis with this chat. And in this example there is no use of it.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
