QUESTION
Been scrolling though every question on StackOverflow and Youtube to find an answer. I'm deploying both WSGI and ASGI/websockets via Django channels on Heroku. It works locally, but it's been giving me trouble during production.
SetupHere's my procfile:
...ANSWER
Answered 2021-Jul-02 at 20:51It doesn't look like application
in routing.py
is doing anything. I see it specified in ASGI_APPLICATION
but, I believe, that's used by the development server (manage.py runserver
). In your daphne
command, you're serving API.asgi:application
which only defines the django ASGI app - the "http" connection handler.
What you need is to replace get_asgi_application()
with a ProtocolTypeRouter
which defines how each protocol is served - "http" goes to the django ASGI application and "websocket" goes to your consumer routes.
Take a look at the Deploying section in Channels documentation. Your asgi.py
could look something like this (I didn't include your consumer imports):
QUESTION
I am downloading Go on my Ubuntu 16.04 computer. I am following this tutorial and I can't progress from this part on youtube https://www.youtube.com/watch?v=YS4e4q9oBaU&t=1810s:
When I created that Main.go an error on VSC console shows up:
...ANSWER
Answered 2021-Feb-26 at 03:44I am guessing the error message comes from https://github.com/golang/go/blob/release-branch.go1.16/src/cmd/go/internal/modload/init.go#L207-L210
In the last line of your ~/.bashrc, you meant export GOPATH=$GOPATH:...
, not export GOPATH=$gopath:...
. Since $gopath is not set, your GOPATH would end up being :/home/santiagoquinteros/code
. The above code doesn't like it.
As others said, you don't need to set GOROOT
. With go1.16, the module mode is the default, so you probably don't need to set GOPATH
but live with the default GOPATH
which is $HOME/go
.
Many things have changed recently. I recommend newer sets of materials like https://golang.org/doc/#getting-started, https://learn.go.dev, https://play-with-go.dev/ , ...

ANSWER
Answered 2020-Apr-21 at 23:52A type assertion for map[string]interface{}
to map[string]string
will fail, because it is a type assertion, not type conversion. It only checks if the interface type is what you think it is, and in this case, it is not. You have to iterate the map[string]interface{}
, and type-assert the values:
