Subscription not processing

Overview

When a subscription is created, it never produces a response. GraphiQL stays in the loading screen.

This is using the example code from this project and I haven’t made any changes. But I did try setting the confirm_subscriptions option on the GraphqlWsConsumer to True, which didn’t change anything (I thought it might).

Environment

Python: 3.7.0 django: 2.2.1 django-channels-graphql-ws: 0.2.0 OS: Ubuntu 18.04.2 LTS

Steps to reproduce

1. Install dependencies

2. Run ./manage.py runserver in the example directory

3. Open GraphiQL at http://127.0.0.1:8000/

4. Create a subscription:

subscription {
  onChatMessageSent(chatroom: "room1", username: "testuser") {
    message
  }
}

No response will be given.

1. Send a chat message:

mutation {
  sendChatMessage(chatroom: "room1", username: "testuser", message: "testing") {
    ok
  }
}

There will still be no response from the subscription.

The following errors are thrown in the browser console:

Firefox can’t establish a connection to the server at ws://127.0.0.1:8000/graphql/. 
The connection to ws://127.0.0.1:8000/graphql/ was interrupted while the page was loading.

Hi @dspacejs ,

In the example in the publish method of OnNewChatMessage subscription there is such code:

# Avoid self-notifications.
if sender == username:
    return OnNewChatMessage.SKIP

return OnNewChatMessage(chatroom=chatroom, message=message, sender=sender)

If you send messages as the testuser user and subscribe as the testuser user, then you do not receive notifications. In other words, being in a chat you only receive other people’s messages, but not your own. So you can change username of the mutation to get notifications. Or you can comment out this condition to duplicate outgoing messages in your inbox.

Does my answer help solve the problem?

It seems the original problem is solved, so I am closing this issue.
