Possible to reference app.ctx from a Blueprint instance?

I’ve added a redis_connection to my app.ctx in the main file:

app.ctx.redis_connection = aioredis.from_url(...)

and I’m able to reference it via a request object:

request.app.ctx.redis_connection...

However, I also need to access the redis_connection in my blueprint, outside of the request object, which is located in a separate file.

blueprint_instance = Blueprint("MyBlueprint", url_prefix="/blueprint_url")

I started looking at this: https://github.com/sanic-org/sanic/blob/main/sanic/blueprints.py#L110 but I’m not sure how it’s referencing the global app.ctx.

I tried this:

bluprint_instance.apps.ctx.redis_connection

and got this error:

sanic.exceptions.SanicException: <Blueprint blueprint_instance> has not yet been registered to an app

How do I get the main app.ctx from the blueprint? Thanks!

ha! I did not realize that the blueprints had access to the listeners!!!

Thank you, this is the correct the solution, and yes it’s very elegant!

Thanks for maintaining this library, it’s by far my favorite web-framework!
