Has anybody had this before?
Here is the question on SO (which is better formatted) -
https://stackoverflow.com/questions/69057713/unable-to-log-in-the-user-using-django-channels-because-connection-is-already-c
I'm unable to log a user in with the login function provided by Django
Channels.
I have this mutation using graphene django -
class SignIn(DjangoFormMutation):
profile = graphene.Field(ProfileNode)
@classmethod
def get_form_kwargs(cls, root, info, **input):
kwargs = super().get_form_kwargs(root, info, **input)
kwargs["request"] = info.context
return kwargs
class Meta:
form_class = AuthenticationForm # username is in fact email for user
fields = ('username', 'password',)
@classmethod
def perform_mutate(cls, form, info):
# form is valid
user = form.get_user()
profile = user.profile
async_to_sync(channels.auth.login)(info.context.__dict__, user)
change_session_and_login(info.context, user)
return cls(errors=[], profile=profile)
This is based on the advice from the package I am using for using
websockets with graphene -
https://github.com/datadvance/DjangoChannelsGraphqlWs#authentication
I am getting this tracebook though, which, to me, suggests a problem with
the async_to_sync.
The only obvious difference I can see is I'm getting the dict by calling
*dict* on the context whereas the example in the link above uses _asdict
(not sure why because this method is not an option for me when I try).
This is the full traceback -
