Provide persistent aiohttp session to async resolvers

[JanMelicharik]

Hey,

I have a backend-for-frontend Django App which fetches data from different APIs and puts them together inside the resolvers.
The problem is I can't get a persistent global session to the resolver.

urls.py

urlpatterns = [
    path("admin/", admin.site.urls),
    path("graphql/", GraphQLAsyncView.as_view(schema=schema, context_value={"session": get_session}), name="graphql"),
]

client.py

async def get_session():
    session = aiohttp.ClientSession(BASE_URL)
    yield session
    await session.close()

resolvers.py

@convert_kwargs_to_snake_case
async def resolve_object(_, info, object_id):
    connection = info.context["session"]

    res = await connection().get("/objects/{object_id}/details".format(object_id=1))
    res.raise_for_status()

    if data := await res.json():
        return {
            "id": data["id"],
            "name": data["name"],
        }

    return None

Is there a way to provide a persistent global aiohttp session to the resolver through the context?

Thanks a lot!
