Re: Channels 2.0 - Exception when sending a message to client

Thank you so much for the detailed explanation. 1) I now understand where my error was - the custom channel I used was passing events to a background worker that was not related to the websocket consumer. This also answers my question about how channel names must be included in the runworker

Kudos for you and all contributors! It’s really amazing. I’m going to send few PRs to django-channels as a payback :) Cheers, Tom > 25. 2. 2018 v 19:46, Andrew Godwin : > > No problem - glad everything else seems to work alright! Getting async > testing working well

No problem - glad everything else seems to work alright! Getting async testing working well has been a long, hard road :) Andrew On Sun, Feb 25, 2018 at 10:37 AM, Tomáš Ehrlich wrote: > Of course! > > It works now perfectly, thank you. Sorry I missed that in docs. > >

I think the change you need to make is swapping in database_sync_to_async rather than sync_to_async - see here: http://channels.readthedocs.io/en/latest/topics/databases.html Andrew On Sun, Feb 25, 2018 at 7:14 AM, Tomáš Ehrlich wrote: > Here's the gist

I've written an email marketing analytics app in Django that I believe will scale. I haven't released anywhere yet though. You might search the web for "write heavy Django" since most analytics is write heavy. On February 25, 2018 9:12:24 AM CST, Raj wrote: >Dear

Re: Channels 2.0 - Exception when sending a message to client

And while we're at it, I'm going to toss out another opinion. I've found it extremely beneficial _for me_ to not try to relate channels 2.0 to channels 1.1. I'm approaching it as if I'm learning about a completely separate package - working from a clean slate so-to-speak. Ken On Sunday,

Re: Channels 2.0 - Exception when sending a message to client

In so far as you are talking about background worker tasks, you are correct. But those statements do not pertain to a websocket consumer that accepts connections from a browser. You can run an application without ever creating a worker task. (Again, I'll refer you to the channels-examples app

Before I get to the guts of my answer, I'd suggest you get Andrew Godwin's "channels-examples" application and read it completely until you believe you understand everything that it's doing. (https://github.com/andrewgodwin/channels-examples) Now, to the extent of my understanding, the

[django-channels] Testing events from post_save signal

Hello, I’ve just migrated my project to django-channels 2.x. Thanks to everyone involved! I’m trying to write a test for a consumer. I have a post_save signal receiver, which sends a message to a group. As I understand, I need to wrap `group_send` with `async_to_sync` because django signals

Hi, "Is it safe"? Well that is your call to make. Depending number of songs it might not be meanful for enduser to see whole list which leads to things like pagination and restricting maximum number of returned entries. On Sun, Feb 25, 2018 at 8:10 AM, tango ward wrote:
