Cannot Login User The Way The Docs Advise #76

Closed rossm6 closed 3 years ago

rossm6 commented 3 years ago

I'm trying to login in my user but getting an error - see traceback below.

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)
        info.context.session.save()
        # change_session_and_login(info.context, user)
        return cls(errors=[], profile=profile)

Notice I'm using dict because the _asdict is not on the context object like the docs suggest (incidentally, why is this?)

Anyway this is the traceback -

graphql.error.located_error.GraphQLLocatedError: connection already closed

Based on a misunderstanding (I think). I was making a http request and this example assumes a websocket request.

I found this post because I ran into the same exact error condition.

I, too, used dict instead of _asdict().

Unit tests worked fine with SQLite3, but failed when I migrated to PosgresQL.

My solution is to just pull all this code out and rely only upon graphql_jwt for authentication.
