Error: "subscriptions are not allowed"

Hey there, trying to get this set up in my project. I’ve gone through the README and set up the required pieces (I think). I’m now trying to use Graphiql to test out a subscription that I set up. When I do, I get this error response:

Subscriptions are not allowed. You will need to either use the subscribe function or pass allow_subscriptions=True

and can see this in stack trace as well:

  File "/Users/levinotik/.local/share/virtualenvs/great-control-ic_1WMqr/lib/python3.7/site-packages/graphql/execution/executor.py", line 176, in execute_operation
    "Subscriptions are not allowed. "

I must be missing something basic. Any ideas on what I’m doing wrong here? Thanks.

Guys, I figured it out, I used the examples given in this tests with their schemas and they worked properly. So on my code I’ll modify it a little bit so that it can receive signals.

And also

@johnpaul89 The rest of your code looks fine at first glance. My guess is that it’s an issue with Django signals. Can you verify that your signals are firing properly? Something simple like this is a good test:

# signals.py
def trigger_graphene_subscriptions(sender, **kwargs):
    print('signals are working')
    post_save_subscription(sender, **kwargs)

post_save.connect(trigger_graphene_subscriptions, sender=ChatMessage, dispatch_uid="chat_message_post_save")

If your terminal doesn’t print that, it means your signals aren’t being read. What you do is try calling your app in init.py using your apps config default_app_config = 'subs.apps.SubsConfig'

Thanks @jaydenwindle for the package.

@levinotik I get an error. Could be an issue with graphql-core: https://github.com/graphql-python/graphql-core/issues/149.
