Hi there,
I'd like to add a few real-time features to an existing pyramid app.
Notifications when queued tasks are complete and some real-time dashboards,
and chat.
I'm thinking of an implementation that doesn't seem like it would be super
invasive, but I though I would check here and see if some of you more
experienced used see any obvious major problems first.
Basically, I want to farm out the realtime elements to a websocket api
server. FastAPI seems like a good framework to do this. But I'd like to be
able to use the traversal machinery in pyramid to hit those endpoints in my
mako templates. So my javascript for opening the websocket can use
the request.resource_url() pattern and I don't have to do a ton of work to
figure out where in the external API I should be connecting.
So for example if in my web app I'm at mywebsite.com/users/123456, then I
can have my websocket enpoint constructed by calling ${
request.resource_url(request.api, 'users', '123456') } and it would
generate a URL as api.mywebsite.com/api/v1/users/123456 where
"api.mywebsite.com/api/v1" is configured in the .ini file.
To make that work I'd create a resource factory that adds the api property
to the Root object with the value set in the .ini file.
The pyramid view would continue to provide the current values from a db
query, so there's a sane default to fall back on in case the websocket
can't connect. For authentication and authorization, I'd server the redis
instance I'm already using for server side sessions and just have the
FastAPI server check that session for whether or not the user is
authenticated/authorized or not.
I think it should be relatively easy to share the SQLAlchemy models between
the two frameworks as well.
Is this totally insane? Is there a better way to do this? Am I setting
myself for a world of pain that I'm not able to see right now? Just
wondering if anyone can offer any guidance before I buckle down and
implement this?
I realize some of this is totally out of scope for this mailing list, and
I"m not asking anyone to comment on whether this is a good idea from the
FastAPI end of things. Just pretend that all just works. I'm really just
curious about the Pyramid implementation.
thanks!
